#### ☞ Got a problem?

1. Search using the upper-right search box, e.g. using the error message.
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.

#### ☞ 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.

GATK version 4.beta.3 (i.e. the third beta release) is out. See the GATK4 beta page for download and details.

# do later versions of GATK (1.5+) warn when Indelrealigner ends prematurely?

Hi,

Apologies if this has been reported but I can't find it in the forum.

We're in the process of upgrading to GATK v2 but have been using v1.5 and have just noticed a few cases where IndelRealigner suddenly ended without warning or any report of an error. See example below where it ended with only ~50% of the BAM file processed. I'm wondering if it's a memory issue if multiple samples were being run concurrently. But more importantly with no alert it makes it tricky for us to identify when this happens. Is this something that's been fixed in later versions e.g. GATK 2.1 i.e. will Indelrealigner report an error when it finishes but the sample has not been processed to completion?

Hi Maria,

If the tool encounters an error that causes it to fail, it should always produce an error message. This sounds like there may be something wrong with your file -- can you check that there are reads throughout and that the contiguous are properly sorted?
