Hi,
I have a general question about pathway analysis in scRNAseq. I'm under the impression that scientists pick pathways relevant to their study from the list of GO terms and present those in a manuscript, but I also read that sometimes people pick the relevant pathways only generated from either upregulated or downregulated DEGs and present these. I'm not sure which way is more accurate or reliable, or is there any specific rule to follow regarding picking the pathways?
