plotting multiple data tracks with the same y-axis limit using Gviz
... I am using Gviz to plot H3K27Ac and RNAPII ChIP-seq data for two experimental conditions, Wt and KO: WT_H3K27Ac <- DataTrack(range = '/path/to/WT-H3K27Ac.bw', type = "histogram", window = -1, name = "WT H3K27Ac", genome = "GRCh38", col.histogram = "black", fill.histogram = "black") KO_H3K27Ac &l ...

ntop parameter in plotPCA(). DESeq2
... Given that the PCA plot is likely to change somewhat depending on the number of genes you decide to specify with the ntop parameter, are there any recommendations on how to best set this value besides arbitrarily setting it at the default of 500/1000? Could including all genes have a negative effect ...

Blocking factors for differential binding analysis with DiffBind
... I have performed ChIP-seq for multiple transcription factors on samples from multiple patients. All ChIPs for each patient where sequenced on different sequencing runs (i.e. TF1, TF2, TF3 for patient 1 was on one flowcell and  TF1, TF2, TF3 for patient 2 was on a separate flowcell etc). I am looking ...

Changing box plot font sizes for axes and labels in DiffBind
... I have been trying to change font sizes for my box plots in DiffBind: dba.plotBox(x, th = 0.05, pars = list(cex.axis=1.5, cex.main=2, cex.lab=1.5)) I have also tried the following variation: dba.plotBox(x, th = 0.05, cex.axis=1.5, cex.main=2, cex.lab=1.5) I assumed that these arguments would b ...

Comment: C: ensDbFromGtf error from gtf file downloaded from GENCODE.
... I missed that, thanks for the catch! Deleting the .AnnotationHub folder cleared the cache and did the trick. I ran ensembldb using both the EnsDb I made from the Ensembl GRCh38 .gtf annotation file (v90) and the one I downloaded through AnnotationHub and both worked well. The only point I would mak ...

Comment: C: DEXSeq-Error in FUN(X[[i]], ...) : subscript out of bounds
... Hi Alejandro, It turns out it was likely the GENCODE gtf file. Switched to the mouse annotation file on Ensembl and it worked well. It is still odd to me considering the count files were created using the GENCODE gtf so I thought it would still result with the same number of lines but I guess not. ...

DEXSeq-Error in FUN(X[[i]], ...) : subscript out of bounds
... I am trying to use DEXSeq to analyze a mouse paired-end stranded RNA-seq data (poly-A RNA capture). I Aligned the reads using STAR and obtained the reference genome and annotation file (which I collapsed with dexseq_prepare_annotation.py) from GENCODE (release m11). I used HTSeq to count exons (usin ...
