A named list of data frames containing feature-level annotations (e.g., gene symbols, CpG IDs, metabolite names). Each entry corresponds to the row metadata of one omics assay.
Format
A named list with the following components:
- Gene Expression
Feature metadata for transcriptomics.
- Methylation
Feature metadata for CpG probes.
- Metabolomics
Feature metadata for metabolites.
