GenomeLocPArser error in SplitNCigarReads

efinlayefinlay IrelandMember ✭
in Ask the GATK team

I don't understand the error message I'm getting and googling it or trying different reference and input files haven't helped.

ERROR MESSAGE: Badly formed genome loc: Parameters to GenomeLocParser are incorrect:The stop position 0 is less than start 38566563 in contig 10

Is the error within the bam file I am trying to split reads within or the reference genome I am aligning to?

Is there any quality control or cleam up method to check if the problem lies within my bam infile? I couldn't find one but when I ran BamIndexStats on the index file of the bam I was trying to use as my infile the line about contig 10 was

10 length= 104305016 Aligned= 61 Unaligned= 3

When I look at the .fai index of my reference genome it has the line

10 104305016 4 60 61

The .dict file also has

@SQ SN:10 LN:104305016 UR:file:/home/bmoran/bin/ens70/Btau.UMD3.1.70.short.fa M5:4c1ab0477783816857a28762f7630deb

When both input and reference files are using the length 104305016 for chromosome 10 I don't understand where the start 38566563 comes from in the error.

Thank you for your help and please let me know if I should supply any more information

Emma

java -Xmx3g -jar /home/bmoran/bin/gatk3.1/GenomeAnalysisTK.jar

    Can you please try to run this with the latest version (3.2)? If the error persists it may be a bug, as someone else reported a similar issue recently. If so we'll need a snippet of data to reproduce the error (see http://www.broadinstitute.org/gatk/guide/?1894 for instructions).

    Hi, I get to see the same error with GenomeAnalysisTK-3.2-2 version as below.
    ERROR MESSAGE: Badly formed genome loc: Parameters to GenomeLocParser are incorrect:The stop position 0 is less than start 12042 in contig chr1

    When I tried using with GenomeAnalysisTK-nightly-2014-09-23-g971ff9b.tar.bz2 from the link Sheila has shared above, I don't get the aforesaid error. Since we are planning to use a stable version for our analysis, is it advisable to use GenomeAnalysisTK-nightly-2014-09-23-g971ff9b.tar.bz2 for our pipelines or should we wait for stable release in future. Kindly suggest. Thanks.

    Hi,

    As the nightly builds are a beta release, it is probably best to wait for the next stable release which should be in the next three weeks.

    Are you running on the same bam file from the previous comments where you already validated and fixed the mate information? You can try adding -fixNDN to your command above.

    @naresh4836 This error suggests that there are problems in your data. You should consider using a different aligner because the one you are using is producing malformed records.

    @naresh4836 It's possible to run another tool on malformed data without getting an error if that particular tool doesn't access the part of the data that is malformed. But this could mask issues that will pop up later in your analysis. Generally speaking it's safer to deal with problems up front. If your aligner is causing malformed data, you should either eliminate the malformed data, fix it or switch to a different aligner.

    Running picard ValidateSamFile on the BAM in question reports no errors. I've tried to identify the offending read but have only been able to reproduce the problem with a BAM file that contains at least two reads. Each of these on its own is fine. BAM files containing one of these (but not both) reads as well as some other reads also appear to be fine but if both reads are present I get the above error.

    I uploaded an archive with the relevant files (bugreport_humburg_20170522.tar.gz) to the ftp server.

    Another thing I noticed while looking at this is that for the reads that are split successfully, the MD tag is not adjusted accordingly. This leaves the BAM records in an inconsistent state.

    Hi @humburg, we are aware that the SplitNCigarReads tool as implemented in GATK 3.x is fairly buggy. We have reimplemented it in the soon-to-be released GATK4 and it's much better, so we won't make any improvements or fixes to the GATK 3.x version anymore. You're welcome to try out the GATK4 version; we'll have documentation coming out on it within the next couple of weeks. In the meantime, our apologies for the inconvenience.
