I'm using the PureCN package to calculate GC-normalized coverage, but I'm receiving the following error below (bottom of page).

After execution is halted, a compressed bed-type text file is produced that has intervals for each of the chromosomes:

chr1:925918-926037 2150 25 1 0.880952380952381

chr1:931005-931124 3449 41 1 0.871875

Can someone help me troubleshoot what the problem is and how to fix the error?

Looks like there are still some issues with the interval files. Can you share the command line and output of both IntervalFile.R and Coverage.R?

The interval file command was:

Rscript IntervalFile.R \
--infile Exome_v1_hg38_Probes_Standard_REMOVE_five.bed \
--fasta GRCh38.d1.vd1.fa \
--outfile ref_check_output/baits_hg38_intervals_hg38probes_grch38.d1.vdl.txt \

Weird. That’s a new one. Can you share the input BED file? Via github issue or email.

But removing the overlaps as mentioned in the warning should fix it. It should do it automatically, but I guess some intervals are repeated multiple times and merged only once.

ADD REPLYlink modified 4 weeks ago • written 4 weeks ago by markus.riester500

Yes, definitely, can I get the email account to send the BED file to? Also, just to be clear, is that the probes BED file?
