Got a problem?

1. Search using the upper-right search box, e.g. using the error message.
2. Try the latest version of tools.
3. Include tool and Java versions.
4. Tell us whether you are following GATK Best Practices.
5. Include relevant details, e.g. platform, DNA- or RNA-Seq, WES (+capture kit) or WGS (PCR-free or PCR+), paired- or single-end, read length, expected average coverage, somatic data, etc.
6. For tool errors, include the error stacktrace as well as the exact command.
7. For format issues, include the result of running ValidateSamFile for BAMs or ValidateVariants for VCFs.
8. For weird results, include an illustrative example, e.g. attach IGV screenshots according to Article#5484.
9. For a seeming variant that is uncalled, include results of following Article#1235.

Did we ask for a bug report?

Then follow instructions in Article#1894.

Formatting tip!

Wrap blocks of code, error messages and BAM/VCF snippets--especially content with hashes (#)--with lines with three backticks ( ``` ) each to make a code block as demonstrated here.

Is GATK DMF-compatible?

Our cluster migrates files to tape on a schedule by file-size, which means this can happen anytime before or during a GATK program call (e.g. when the file has not been touched during a long program run). It seems to me that GATK (UnifiedGenotyper, v1.5-30-g27e7e17) is not checking if files are partial but continues with binary zeroes instead of valid data when it tries to read from the offline file.
(If it were a C program, they would be looking for "open" system calls which use either of the O_NONBLOCK or O_NDELAY flags.)

GATK does not seem to throw a warning/error and the resulting file (vcf) look OK at first glance except that the DMF system seems to think that the used (offline) file was being treated suspiciously and the overall runtime is inflated.

Thanks for your comment.
