Hi Jen, Thank you! It worked on the original BWA, only when it is aligned to hg19 (failed when the alignment was to hg_g1k_v37. However, it doen't work on BAM or SAM files after sorting with Select Matching pattern: XT:A:U or after filtering the BWA results with Filter SAM on bitwise flag values. Is there any solution? Thanks, Lilach 2012/6/18 Jennifer Jackson <jen@bx.psu.edu>
Hello Lilach,
Please try running pileup on the original BWA output - (SAM is an OK
input with this tool) and let us know if you continue to have problems.
Hopefully this helps,
Jen Galaxy team

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 0 bytes 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, Lilach
The parameters are:
