BiocParallel errors when running regionMat()

[rosshandler]

Hello,

Thank you for making this tool. I would like to use derfinder starting from a set of bam files. I have loaded the files using load coverage and it ran without problems:

lC <- loadCoverage(
files=files,
chr="chr21",
cutoff = NULL,
filter = "one",
chrlen = NULL,
output = NULL,
bai = NULL
)

I then tried to run regionMat without any parallel specification but still I get an error referring to BiocParallel:

regionMat <- regionMatrix(
fullCov=lC,
cutoff = 5,
L = rep(500,length(files)),
totalMapped = 8e+07,
targetSize = 8e+07,
runFilter = TRUE,
returnBP = TRUE
)

By using totalMapped equal to targetSize, regionMatrix() assumes that you have normalized the data already in fullCoverage(), loadCoverage() or filterData().

Are you familiar with this error? If there is other info I should provide, please let me know.

All the best,
Ivan

Hi again, I have a brief update. If I run the function loadCoverage with filtered > 0. Then I have a different error, but at the same place:

It does not change whether I change any of this parameters.

regionMat <- regionMatrix(
fullCov=lC,
cutoff = 5,
L = 500,
totalMapped = 8e+07,
targetSize = 8e+07,
runFilter = TRUE,
returnBP = TRUE
)
