TiDEomics 0.99.4
TiDEomics (Time-course Differential
Expression analysis of omics data) is an R package for
multi-group time-course omics analysis built on SummarizedExperiment,
especially for comparison of more than two conditions across time.
TiDEomics provides:
An integrated workflow from data processing to functional interpretation, on different omics data types in feature x sample matrix format, with handling of missing values.
An approach to separate time-dominant, group-dominant, and group-specific temporal effects through the combination of pairwise differential expression, variance decomposition, and co-expression module analysis (WGCNA).
A filtering strategy based on residual variance after mixed-model variance decomposition, prioritising features with structured differential expression over unexplained variation. In comparison, traditional filtering by total variance or coefficient of variation is less appropriate when biological variation across groups and time course is expected.
Existing packages on time-course omics analysis are available, typically
designed for transcriptomics data. Some packages are limited to two-group
comparisons (e.g. splineTimeR) or expect raw sequencing counts (e.g.
ImpulseDE2, TCseq). maSigPro supports multi-group time-course DE analysis
via polynomial regression, complementary to TiDEomics with fewer
assumptions about temporal trends. TiDEomics also integrates QC, filtering
and downstream functional enrichment within the same workflow.
TiDEomics incorporates Trendy (Bacher et al. 2018) which operates on single time
series to estimate breakpoints per group per feature,
and derived variance decomposition from PALMO (Vasaikar et al. 2023) and introduced
residual variance as a filtering criterion.
This tutorial demonstrates a basic workflow, explains key parameters, and gives practical tips.
Key features covered:
Preparing input: Create a SummarizedExperiment object with the data
matrix and sample annotation, with checks for correct formatting.
Quality control: Visualise value distributions and missingness patterns.
Normalisation, grouping and merging replicates: Normalise each feature to the starting time point when focused on changes from baseline. Transform the data for analyses that require single groups or single time series.
Sample relationships visualisation (correlation matrix, PCA, UMAP): Explore global structure and major sources of variance, check for batch effects, and identify features driving PCs.
Pairwise differential expression (by time or group): Identify DE features between pairs of time points within each group, and between pairs of groups at each time point.
Classification by feature property (randomness and overall fold change): Classify features into different categories (e.g., non-random vs. random, differentially expressed vs. stable) based on properties including trend significance and maximum fold change.
Segmented regression with Trendy: Estimate breakpoints for each feature in each group and summarise dynamic patterns.
Variance decomposition modified from PALMO: Quantify relative contributions
from Time, Group, and Residual, distinguish time or group-dependent
DE features and “noisy” features.
Module identification with WGCNA: Identify co-expression modules with different temporal and group-specific patterns.
Functional enrichment (gene ontology, drugs, etc.): Interpret biological meaning of identified DE features and modules.

#> TiDEomics expects:
data: log2-transformed data.frame
sample_ann: data.frame with columns:
Sample: sample names, match column names of dataGroup: experimental groupTime: numeric time pointReplicate: replicate ID (optional, auto-generated if absent)Batch: batch ID (optional)Subject: biological subject ID for repeated-measures designs
(optional, set via subject_col)Example: subset of GSE263759 data set published in Traxler et al. (2025).
log2(CPM + 1)TiDEomics expects log-transformed, normalised data as input. The core workflow
is compatible with any quantitative omics data in a feature x sample matrix.
Enrichment analysis (enrichGO_list, enrichGO_rank, enrichR_list,
enrich_msigdb) requires gene identifiers and is not applicable to non-gene
features (e.g., metabolites, lipids).
Batch correction should be applied before input if batch effects are present.
For the most common scenarios in transcriptomics and proteomics:
RNA-seq data should be normalised for sequencing depth and composition bias
before TiDEomics, e.g. with TMM. The tutorial uses log2(CPM + 1) for
simplicity. For pairwise differential expression, trend = TRUE can be used
to account for the mean-variance relationship. See below section on
pairwise differential expression for details.
MS-based proteomics data processing software may include normalisation when
producing protein x sample matrix. Depending on software and settings,
manual normalisation and log transformation may be required, e.g. median
normalisation. Missing values are accepted in most TiDEomics functions,
and a basic imputation function impute_groups() is provided.
We present the workflow as below sections, explaining the usage and parameters.

By default, TiDEomics generates a default color palette (scales::pal_hue())
based on the number of groups. A custom palette for each group can be set with
set_custom_palette(), which will be used in all subsequent plotting functions
where applicable.
plot_distribution(data_obj, facet_by = "Group")
#> Picking joint bandwidth of 1.3
#> Picking joint bandwidth of 1.31
#> Picking joint bandwidth of 1.3
#> Picking joint bandwidth of 1.32If distributions differ significantly, consider global normalisation (e.g., quantile, median) before using TiDEomics.
For data with missing values (e.g., proteomics), plot_ID() and
plot_missing() can be used to check missingness patterns.
normalise_to_start() subtracts the baseline value from each feature at
starting time point (referred to as time 0) or the first available time point
if the feature is missing at time 0.
Two modes are available for defining the baseline:
by_subject = FALSE (default): group-level baseline, mean of all samples at
starting time point in the group. This is used when no subject-level
information is available or when between-subject baseline differences are
of interest.
by_subject = TRUE: subject-level baseline, mean of all samples at starting
time point for each subject. This is used when subject-level information
is available and the focus is on subject-specific changes from baseline.
data_obj <- normalise_to_start(data_obj)
#> Normalising to group baseline at each feature's first non-NA time point.Both original and time-0 normalised data are stored in the
SummarizedExperiment object and downstream functions allow the user to specify
which to use for each analysis (assay = 1 or 'orig' for original,
assay = 2 or 'norm' for time-0 normalised).
Use original data when absolute abundance differences across groups are of interest (e.g., constitutively different baseline levels). Use time-0 normalised data when relative changes from baseline are of interest.
Use split_groups() to obtain group-specific SummarizedExperiment objects
and merge_replicates() to average replicates for analyses / visualisation
that require single time series for features, including
calc_feature_property(), run_Trendy(), plot_modules_v() and
plot_modules_h().
Correlation matrix can be plotted with plot_cor_matrix() to check sample
relationships and potential batch effects.
plot_cor_matrix(data_obj,
method = "spearman",
label_rep = TRUE, label_batch = TRUE,
cellwidth = 2, cellheight = 2
)High within-replicate correlation and clustering by Group or Time increase
confidence in data quality and downstream analysis. If batch effects are
present, consider batch correction before using TiDEomics.
There are multiple functions for PCA and UMAP:
Use plot_pca() to visualise sample relationships in 2D. Output loadings
can be used to identify features driving the principal components.
Use plot_pca_3D() to visualise sample relationships in 3D.
Use PCAtools::eigencorplot() to correlate PCs with Group and Time.
Use plot_umap() for UMAP and set seed for reproducibility.
Features with missing values (NA) are automatically excluded from PCA and
UMAP. Consider imputation (e.g., group-wise minimum imputation with
split_groups(), impute_groups() and merge_groups()) to include features
with missing values in PCA and UMAP.

DE_between_time():
Compare pairs of time points within each group.
Output: Nested lists of DE statistics tables, including all features or only significant features.
Use plot_DE_between_time() to summarise number of DE features per pair of
time points per group.
When a Subject column is provided via subject_col in create_input(),
DE_between_time() automatically uses a paired design via
limma::duplicateCorrelation(block = Subject).
DE_between_group():
Compare pairs of groups at each time point.
Output: Nested lists of DE statistics tables, including all features or only significant features.
Use plot_DE_between_group() to summarise number of DE features per pair of
groups with line plots.
Common parameters for both functions:
assay: index of assay to use (1 = original, 2 = time0-normalised if
available)
filter: minimal number of non-NA replicates for the feature to be included
in DE testing (e.g., filter = 1 means requiring features to have at least
1 non-NA value at both time points in the specific group, or in both groups
at the specific time point).
trend: passed to limma::eBayes(). Set to TRUE for RNA-seq
count-derived data to model the mean-variance trend.
FALSE (default) is usually appropriate for other types of data,
where the trend is typically weak.
The trend can be visualised with limma::plotSA() with elements of
$fit_list of both functions’ output.
Default thresholds for DE are p.adj < 0.05 and |log2FC| > 1.
plot_DE_between_time() and plot_DE_between_group() allow re-filtering
DE by setting new thresholds.
Please note that the example data only has two replicates per time point. More replicates are recommended for robust pairwise DE analysis.

logFC_thres = 0.5, adjP_thres = 0.05, label = TRUE)calc_feature_property() computes per-feature properties:
P_trend: calculated with randtests::bartels.rank.test(), testing for
non-randomness of the time profile (i.e., whether the feature shows a
significant overall trend across time points).
Max_FC: maximum fold change across time points, calculated as the
difference between the feature’s maximum and minimum abundance across time
points. This captures the overall magnitude of change across the time
course, regardless of the specific time points at which changes occur.
Max_FC_time: the difference between time points with maximum and minimum
abundance, providing information about the direction (up or down) and
duration of changing.
Exp_threshold: user-set value threshold for a feature to be considered
expressed in a sample. This can be used to filter features based on
expression level, e.g. setting threshold = 0 means that only
values > 0 (log2(CPM + 1) > 0, i.e. CPM > 0 in the tutorial dataset) are
considered expressed. The default is NULL, which means all non-NA
values are considered expressed.
T_total, T_exp and Exp_ratio: number of total time points, number of
expressed time points with values > Exp_threshold (or non-NA values if
threshold = NULL), and proportion of expressed time points (T_exp /
T_total).
Rho_time: Spearman correlation with time (positive = up, negative = down).
Requires at least 3 expressed time points.
Peak_ratio: proportion of time points that are local maxima (0 = monotonic,
higher = more oscillatory).
Log2_CV: log2(1 + SD / |mean|), coefficient of variation for relative
temporal variability.
AUC: area under the time-0-normalised curve from assay 2. Positive =
net increase from baseline, negative = net decrease. NA if assay 2 is not
available (run normalise_to_start() first).
The property values can be used to classify features into different categories
(e.g., non-random vs. random, differentially expressed vs. stable) for
downstream analysis and interpretation. For example, features with
P_trend < 0.05 and Max_FC >= 1 can be candidates for non-randomly
overall-changing DE features.
Note:
When replicates are present, the input should be the mean of replicates at
each time point, output of merge_replicates().
The function is set to require at least 3 values > threshold to
calculate P_trend.

run_Trendy fits segmented linear models to the time course for each feature
to estimate breakpoints with Trendy package (Bacher et al. 2018), see
Trendy
for details.
Notes:
The function requires complete input (no NA). When data contains missing
values (e.g. proteomics), use impute_groups() to impute (default: group
minimum; pass fun = function(x) min(x) / 2 for half-minimum,
fun = median for median imputation, etc.), or restrict to features with
complete data.
If feature is not specified, the function will run on all features
filtered by expression / missing rate, which requires running
calc_feature_property() before impute_groups().
Number of time points needed = [# segments] x [minimum number of samples in a segment]. For example, when # segments = 2 (maxK = 1) and minNumInSeg = 2, at least 4 time points are needed.

Variance of each feature is decomposed by linear mixed models (LMM) into
contributions from Group, Subject (when present), Time, Residual, and
optionally Group:Time (or Subject:Time) interaction, which captures
group-specific temporal patterns. This helps to identify time-dependent
features, group-dependent features, and “noisy” features with high residual
variance.
Interpreting the components:
High Time: time-dependent features, dynamic along time course consistently
across groups. Good candidates for run_Trendy() or other time-focused
analysis.
High Group: group-dependent features, stable along time but differentially
expressed between groups. May be baseline biological markers.
High Subject (when present): features with baseline differences between
individuals, biologically meaningful in patient studies.
High Residual: unexplained variation, consider excluding for
downstream analysis.
The function decomp_variance() is inspired by PALMO::lmeVariance()(Vasaikar et al. 2023).
Group and Time are always included (auto-skipped if only 1 group or time point
present). Subject is included when present in colData. Set
interaction = TRUE to add Group:Time (or Subject:Time with Subject) as a
variance component capturing group-specific temporal patterns. Sufficient
replicates per combination are required for stable estimates.

The following is a brief demonstration of how to prepare input and run WGCNA with TiDEomics functions.
Filtering strategies:
Features with too many missing values will be automatically removed with
WGCNA::goodGenes() included in the prepare_WGCNA() function, and can
also be pre-filtered with the calculated feature property (output of
calc_feature_property() and summarise_feature_property()).
Residual variance can be used to exclude noisy features.
It is not recommended to filter by differential expression before WGCNA, see WGCNA FAQ.

dplyr::pull(Feature)
data_obj_wgcna <- data_obj[filter_wgcna, ]Prepare data format and choose power:
prepare_WGCNA() prepares the input for WGCNA and helps to choose the
soft-thresholding power. Check the scale-free topology fit indices to confirm
that the chosen power is appropriate.
Reasonable powers are less than 15 for unsigned or signed hybrid networks, and less than 30 for signed networks, to reach scale-free topology fit index > 0.8, and mean connectivity (mean.k) not too high (in the hundreds or above). See WGCNA FAQ for details.

Use run_WGCNA() with the output of prepare_WGCNA(), and visualise the
resulting modules with plot_WGCNA().
run_WGCNA() is a wrapper of WGCNA::blockwiseModules(), which runs the WGCNA

classification), use enrichGO_list() and plot with plot_GO().
Optionally, use simplify = TRUE with enrichGO_list() to simplify the GO
results by removing redundant terms (default: FALSE).

Enrichment can also be performed against the Molecular Signatures Database
(MSigDB) via enrich_msigdb(),
which queries the gene sets with msigdbr::msigdbr()
and runs a hypergeometric test across
user-selected collections (Hallmark, GO, etc.) or specific gene sets.

be performed with enrichR_list(), which wraps enrichR::enrichr().
Available databases can be checked with enrichR::listEnrichrDbs().
enrichGO_list(), enrich_msigdb() and enrichR_list() all
return a named list of data.frames (one per category for enrichGO_list,
one for enrich_msigdb(), one per database for enrichR_list()) with
Cluster and Description columns, compatible with plot_modules_h().
Enriched terms can be added to the module profile plot with
plot_modules_h(), which is similar to plot_modules_v() above but
horizontally aligned with annotation of the modules with their top enriched
GO terms. The plotting function is adapted from ClusterGVis
package (Zhang et al. 2026).

enrichR databases) can be displayed side-by-side
by passing a vector to enrich_category. Features of interest can
be marked on the heatmap or shown as an annotation column via
mark_features and enrich_category = "Hub features". The
enrich_p_threshold parameter controls per-category p-value colour-coding
of enrichment terms; set to NA for “Hub features”, which use auto-assigned
colours instead.
Hub features can be extracted by WGCNA module membership (the correlation of
the feature with the corresponding module eigengene) with extract_hubs()

TiDEomics uses SummarizedExperiment as the central data container. It keeps the feature x sample matrices, sample annotation, and feature metadata synchronized during normalisation, splitting, and filtering. The use of multiple assays within the same object also allows original (“orig”) and baseline-normalized (“norm”) data to remain linked throughout the workflow.
As SummarizedExperiment is a standard Bioconductor container, TiDEomics data can be passed to other Bioconductor tools for further custom analysis and visualisation. For example, iSEE interactive SummarizedExperiment browser can be used to explore the data in an interactive Shiny app.
prepare_tide() output can be converted to a
DeeDeeExperiment
object for formatted summary. The nested DE and enrichment
results can be flattened with flatten_DE() or flatten_enrich() before
passing to the DeeDeeExperiment constructor.

#> Returning only the original object.TiDEomics supports two experimental designs, auto-detected from the sample annotation:
create_input(data, sample_ann)
– each sample is independent. LMM uses (1|Group) + (1|Time). DE uses
unpaired designs.create_input(data, sample_ann, subject_col = "PatientID") – same
subjects tracked across time points. LMM adds (1|Subject).
DE_between_time() uses paired design via limma::duplicateCorrelation().
normalise_to_start(by_subject = TRUE) subtracts each subject’s own
baseline. merge_replicates() and plot_trend() compute statistics across
subjects.Users can ask different biological questions and use different functions in TiDEomics to answer them. For example:
Which features change over time in each sample group? -> DE_between_time(),
calc_feature_property(), run_Trendy().
Which features differ between groups at the same time point? ->
DE_between_group() (For starting time point, use assay = 1; for later
time points, use assay = 1 for original input data, or use assay = 2 for
change-from-baseline).
What is the temporal pattern for individual features? -> run_Trendy() +
summarise_Trendy() + extract_segment_trends().
Which features are noisy vs biologically driven? -> decomp_variance() +
plot_variance(), noisiness can be represented by Residual variance.
What co-expression modules are present and what are their temporal profiles?
-> prepare_WGCNA() + run_WGCNA() + plot_modules_v() or
plot_modules_h().
What biological processes are associated with the genes of interest (e.g.
co-expression modules, differentially expressed genes in each sample
group)? -> enrichGO_list() + plot_GO().
What biological processes are associated with the genes ranked by their
property (e.g. time or group contributed variance)? -> enrichGO_rank().
How to normalise the data? -> normalise_to_start() to focus on changes
from baseline; apply global normalisation (quantile, median) and batch
correction when appropriate, before create_input().
How to handle missing values? -> impute_groups() for run_Trendy.
plot_pca() and plot_umap() automatically exclude features with missing
values. prepare_WGCNA() filter out features with too many missing values.
