Hi all,

I want to to perform Gene Ontology (GO) Enrichment of Genes Expressed in specific clusters and I am following this tutorial but in the output I cannot find which genes are associated per terms. How do I find them?

Also (more theoretical question) is it correct to perform GO in a subset of cluster (eg. all cluster expressing a specific marker regardless the cell type)?

Thank you very much!

To find the genes associated with the gene ontology term, I would look up the exact GO term in this dataset (https://www.gsea-msigdb.org/gsea/index.jsp). That's usually how I do it. If you want a pathway analysis pathway with good visualizations, look into SCPA (https://jackbibby1.github.io/SCPA/).

For your second question, I'm not sure what you're asking. Are you asking about the validity of performing pathway analysis in one of your clusters, with a comparison between two conditions? Or do you want to perform pathway analysis on ANY cell expressing your gene of interest?

thank you very much! (I have missed the reply for some reason)

I am asking what it is the best practice for pathway analysis in scRNAseq when you have an integrated dataset? Do I have to do it for each cluster? for the whole dataset or can I do it for all cells expressing X genes (eg. Sox2+ cells which corresponds to maybe a couple of clusters)?
