Comment: C: What is the proper way to modify mcols of a GRanges inside a GRangesList?
... As of today, I do not manage to reproduce the examples above.  After running example("GRangesList") to create a grl object with "score" and "GC" mcols, here is what I get: > grl[,"newColumn"] <- "new value" Error in `[<-`(`*tmp*`, , "newColumn", value = "new value") : replacement value ...

Circular plot of transcript models with ggbio.
... Hello, ggbio is great to plot transcript models, and great to plot features on circular genomes, but I could not find a way to plot transcript models on a circular genome. Is it unsupported at the moment ? Thanks a lot for this brilliant package. ! Charles ...

Comment: C: bplapply slow to decide number of cores
... Indeed the speed has a lot to do with the session. I tried the bplapply command in a fresh session and it took 0.6 s.  Then I loaded GenomicRanges and it took 1.4 s, then I added SummarizedExperiment, MultiAssayExperiment and rtracklayer,  and the elapsed time rose to 2.0, 2.3 and 2.8 s respectively ...

bplapply slow to decide number of cores
... I am surprised that bplapply() takes a few seconds to detect the number of available cores, while multicoreWorkers() or MulticoreParam() are fast when they run by themselves: > system.time(BiocParallel::bplapply(1:1e2 , function(x) order(rnorm(n=1e3)), BPPARAM = MulticoreParam())) user syst ...

Comment: C: Generic functions for DataFrames of Rle objects ?
... Thanks a lot Hervé! It took me some time to understand the obvious, but the DelayedArray wrappers are exactly what I needed. Would you recommend to I wrap in DelayedArrays just before performing matrix-like operations, or to use the DelayedArray class as the base class for the assays in the Summari ...

Comment: C: CAGEr BAM files size issue
... Hi Hervé and Magda, thanks for the report and the guidance. getCTSS() loads the BAM files with Rsamtools::ScanBam, and then extracts the qualities from the returned object, in which they are stored as a PhredQuality object. For each read, an average quality is calculated, and that requires the Phr ...

Generic functions for DataFrames of Rle objects ?
... Dear BioC developers and community, I am using more and more DataFrames of Rle values, typically for transcriptome expression data, and I end up writing more and more functions that take a DataFrame, lapply a function that unpack the Rle, apply a second function, repack the Rle and convert the resu ...
