Many DESeq2 P values are 0 thus preventing generation of a rank list for GSEA
... Hi Everyone, In my DESeq2 reuslts files, the smallest 100 P-values are 0 (as the smallest floating point value in R is 2.225074e-308). I am wondering if there is any way to discern the unrounded values of these P-values as they are needed in order for me to produce a rank list for gene set enrichm ...

Older Microarray probes not matching Ensembl genes
... Hello, I have some old microarray data from a zebrafish experiment done years ago. The probes are Agilent G2519f. When i input a small subset of probes into Biomart on ensembl to get genes, over half of these probes do not seem to be representing a gene. Is there some way to update the probes to t ...

Comment: C: Tophat2 Accepted hits Visualization and HT-seq Count not agreeing
... Yeah, I notice that also. But I also see reads aligning to exons, therefore stranded = reverse should be giving some counts correct? Unless all these reads are being labelled as ambiguous due to overlapping another gene on the other strand? ...

Comment: C: Tophat2 Accepted hits Visualization and HT-seq Count not agreeing
... In tablet, how can I tell which strand a read pair is mapping to? The odd thing is that for other genes on the reverse strand, HT-seq count seems to be counting them. ...

Tophat2 Accepted hits Visualization and HT-seq Count not agreeing
... Hi all, I seem to be have problems with Tophat2 or HT-seq counts. I am visualizing the tophat BAM file using Tablet. The trouble is, there seems to be reads aligning to this specific gene (spi-c, zebrafish, reverse strand) however HT-seq counts (using stranded = reverse) is counting 0 reads for th ...
