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 ...

Comment: C: Best way of creating a large RleMatrix
... Thank you! Does the new constructor affect how the chunks are structured? If you construct an RleMatrix from a DataFrame of Rle's, is the RleMatrix then chunked by column? ...

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 ...

Comment: C: DelayedArray seeds: SolidRleArraySeed vs ChunkedRleArraySeed vs DataFrame of Rle
... Thanks for the detailed response! I'm considering updating the CAGEfightR-package from using dgCMatrix to using DelayedArray instead (giving the new addition of parallel processing and quick summaries from DelayedMatrixStats, particularly rowsum). Using RleMatrix seems like the obvious choice for re ...

Comment: C: DelayedArray seeds: SolidRleArraySeed vs ChunkedRleArraySeed vs DataFrame of Rle
... Thank you for the detailed explanation. A few follow up question: - Why is it beneficial to store the data as a single Rle in SolidRleArraySeed? Doesn't that limit to the total size of the matrix since it spans all columns? - If you chunk a ChunkedRleArray seed by column, how is that different from ...

DelayedArray seeds: SolidRleArraySeed vs ChunkedRleArraySeed vs DataFrame of Rle's
... After reading the vignette for DelayedMatrixStats, I'm confused about the mention of two types of RleArray seeds: SolidRleArraySeed & ChunkedRleArraySeed What's the difference between these two seeds and a simple DataFrame of Rle's as seed? Are there perfomance/memory differences between them? ...
