Hi,
I am trying to do variants call with "generate pileup".
My steps where:
1. BWA
2. select only lines with the pattern Matching pattern: XT:A:U
3. SAM-to-BAM

4. then I tried to use "Generate pileup from BAM dataset"
However, it does not work, and I get the error message:

114: Generate pileup on data 97: converted pileup An error occurred running this job: Samtools Version: 0.1.16 (r963:234)
Error running Samtools pileup tool
Floating point exception

Did I do anything wrong, or is it a bug?
The parameters are copied below.

Thanks,
