... Hi,
I am learning maftools, a R package, to analyze some mutation data but I am really confused about the percentage of top 10 mutated gene in plotmafSummary result when reading your delicate vignette. I made a screenshot and show it as the follows:

... Yeah, it is true that the result would change no matter what seed you set. But try to set the nPerm = 10000 instead of 1000 by default, and that would quite stable just like you set a seed! ...

... Hi there,
In the output of GISTIC2.0 algorithm for copy number analysis, there is a generated heatmap Segmented Copy Number (raw_copy_number.pdf and raw_copy_number.png).
The png file is shown as the following:

... Hi there,
I am using CHAMP to perform differential methylation analysis, including DMP and DMR.
Regarding DMR, I used DMRcate algorithm and I am a little bit confused about the result.
In the derived table of DMRcate embedded in CHAMP, I got a column of overlapping.promoters.
For example:
...

C: How single sample GSEA works
... No, this parameter was just like it was. OMG it is really confusing...
Maybe I should just calculate the average value for each signature and at least that would be more interpretable. ...

... Hi there,
I have some mouse rna-seq data and would like to do some functional enrichment analysis, but I do not have such robust signatures designed just for mouse, such as MSigDB.
Thus, I wonder is it logical to convert mouse gene to human gene, and perform the typical downstream analysis just li ...

C: How single sample GSEA works
... Sorry the code is another test, the 'actual' score was calculated by ssgsea method. The heatmap showed the expression of all genes included in the first pathway, which show in the scoremap.
I used specific gene list corresponding to a pathway to make a signature.
In the meta.sig, there are 23 pathw ...

Comment:
C: How single sample GSEA works
... Thanks, the meta.sig is a list contains 23 metabolism related pathways. Each element in the list is a vector of genes corresponding to the specific pathway.
I am not asking the order because the order is fixed either in the heatmap or scoremap. I just wonder why the enrichment score would be totally ...
