Answer: A: Genome database and transcription database have different lengths
... You are correct, CAGEfightR is complaining that the two genomes (obtained via seqinfo()/seqlengths() ) are not identical. I have seen a couple of people having similar problems, so CAGEfightR is probably currently a bit too strict in enforcing this. We will probably remove this error in future versi ...

Comment: C: CAGEFightR to get CTSS from CAGE error
... This could be an issue with the BigWig-input files. CAGEfightR assumes all ranges in the BigWig is exactly 1, i.e. a single count for each single basepair (traditional CTSS format). This could be checked using something like this: `gr <- import(bw_file)` `table(width(gr))` ...

Comment: C: Adding a legend to a GeneRegionTrack?
... The use case was manually setting colors of items on a GeneRegionTrack, for example colouring by strand. I figured a somewhat hacky workaround: You can use an OverlayTrack, to put a DataTrack with no data but a legend on top of a GeneRegionTrack. You have to do some fiddling to make sure the feature ...

Adding a legend to a GeneRegionTrack?
... Quick Gviz question: For a DataTrack, there is an option to add a legend via setting legend=TRUE I'm using the feature argument in GeneRegionTrack to color different features. Is there a way to add a legend to the track indicating what the colors mean? Simply supplying legend=TRUE does not work. ...

What's the recommended way to overwrite the seqinfo of a GRanges?
... I'm having some difficulties when using rtracklayer to import BigWig-files: import.bed includes the genome argument, which correctly sets the seqinfo on the resulting GRanges. However, import.bw does not have a similar argument; The resulting GRanges will have the seqinfo stored in the BigWigFile. ...

Comment: C: Correct use of Nested/Stage-wise testing with limma/stageR for 3-group design.
... Thanks for the detailed comment! I don't think the the two-stage approach you suggest would be entirely appropriate here, as the two timepoints have a very different number of pairwise differences (more than twice as many difference between sites on the segment time point). Would it still be correc ...

Correct use of Nested/Stage-wise testing with limma/stageR for 3-group design.
... I'm analysing an RNA-Seq dataset with the following study design: Three locations (e.g. A, B, C) at two different times (e.g. time 1 and 2), everything in triplicates. I'm interested in finding DE genes within each time point: A1 vs B1, A1 vs C1, B1 vs C1, and similarly for the second time point. I ...

Best way of creating a large RleMatrix
... What's the preferred way of creating a large RleMatrix? The documentation page ?RleMatrix only covers how make an RleMatrix from a single Rle (which doesn't work for very large RleMatrix objects) First creating a normal matrix and then coercing to RleMatrix, requires keeping the original matrix in ...
