... Thanks for your reply. I thought this could be related to the functions of "survival" package, that's why I posted here. I posted in CV and Biostars just now as well. Hopefully will hear something back. ...

... Hello BC community, I'm analyzing TCGA data to investigate the effects of lncRNAs on survival. Among other things, I wanted to calculate a univariate CoxPH model for each gene to find genes whose expression levels have a significant correlation with survival outcome. I realize that I'm not testing ...

... Thanks for your message, but I'm not sure if it resolves my question. I can visualize the results as a data frame or in the form of a graph, but the results inherently don't show which gene sets are enriched in one vs the other phenotype. What I'm looking for is something equivalent to positive and ...

... Sorry, it took me a while to respond. I'm attaching a csv file with the gene ranking. I don't think it is the same as the initial analysis I posted in this thread, but the same issue persists here as well.  https://nofile.io/f/3Skt1b8xqZ1/neutrophil_ranked_genes.csv ...

... I think might have an idea... The sc-rnaseq data type doesn't really feature a high dynamic range of measurements. Unlike counts obtained from a bulk RNAseq, individual cells often register a few copies of a transcript. Therefore, it isn't uncommon to find expression values of 1-3 per gene per cell. ...

... Hello,   I'm analyzing enrichment scores of MSigDB gene list in the subsets of my single cell rnaseq data. I'm using S2N metric implemented in GSEA (I just wrote a function to perform this for me and feed it into fgsea). I got everything to work but I'm trying to ensure what I see is actually real ...

... I've been playing with GSEA analyses in the last couple of days by using my single cell rnaseq data. I automated sample subsetting, gene ranking (S2N method, but can be replaced by other metrics), performing GSEA (using fgsea package) and reporting the top hits. If you are still interested in this t ...

... Dear BC community,   I have performed gene set enrichment analysis by using clusterprofiler package. I prepared a gene list by using package vignettes and got everything working, but I'm having a bit of a hard time interpreting the results. I read pretty much all the questions and the vignettes ab ...

... I actually figured out the problem. There was a mistake in my code while resulting in erroneous output. I can now confirm that regardless of the input matrix size, as long as the column annotations (ie ref vs samp are done properly, GAGE gives the same output. Hopefully, this might help somebody ...
