Identifying top expressing genes per cluster in single-cell RNA-seq data requires running analysis after Seurat clustering to highlight characteristic genes for each cell population across all cells.

Pathway enrichment for top cluster genes interprets cluster-level gene signatures to provide a preliminary overview of functional signatures and broad cell-type composition prior to T/B cell filtering.

Yes, you can perform pathway enrichment using KEGG and MSigDB databases to analyze Seurat cluster markers, generating visualizations like bar and dot plots to interpret the functional signatures.

You need a pre-selection overview of all cell populations when you want to assess broad cell-type composition and quality before applying downstream filters like T/B cell selection in your single-cell analysis.

The best way to visualize functional signatures of cell clusters before T/B cell selection is to identify top expressing genes per cluster and generate enrichment bar or dot plots from databases like KEGG and MSigDB.
