... Thanks a lot for this comprehensive answer and these great suggestions.
Although there are scenarios where a CNV can affect gene expression on a genome-wide
scale (eg by modulating the expression of a coinciding transcription factor, which
in turn regulates distal genes), you rarely have the power t ...

... Dear edgeR-Team,
I have around 200 samples for which I have
1) CNV data, ie. a matrix X (regions x samples) in which a cell is either 2 (normal diploid), 0/1 (loss), or 3/4/5/... (gain),
2) RNA-seq data, ie. a matrix Y (genes x samples) storing the raw RNA-seq read counts.
Now I want to find for ...

... Not sure whether this is what you are aiming for with rtracklayer::liftOver, but I assume general consistency with the UCSC online liftOver (https://genome.ucsc.edu/cgi-bin/hgLiftOver) to be a desired feature for many users.
I can think of several good use cases, but to give you a specific one:

... Hi Ai Chen,
(1) perhaps you want to change the title of your post to something more precise such as:
"Error when using EnrichmentBrowser's sbea function with RNA-seq data"
(2) You maybe by accident also created another post

reporting on the same error t ...

... Hi Florian,
BTW: great work on the Gviz package, I found it to be the best among its kind and recommend it also to others!
Your suggestion to fill gaps in the bands df with gneg bands indeed resolved the error, however now the plot looks weird.
Please find the dataframe below. I used the code as ...

... Hi,
As other users encountered as well: There is no information available on cytobands for my organism.
Specifically, I'm plotting chr12 of bosTau6 giving me an empty ideogram, which is fine.
gen <- "bosTau6"
chr <- "chr12"
start <- 71959908
end <- 77206892
ideoTrack <- ...

... Hi,
you can use the 'volcano' function from the EnrichmentBrowser package in case you have your data in an ExpressionSet.
Otherwise you can just use these lines:
I assume <fcs> to be a vector of log2 fold changes and <ps> a vector of e.g. t-test derived p-values:
plot(x=fcs,
