# GATK 2.7.4 -mbq and HaplotypeCaller

USAPosts: 12Member

Dear GATK Team,

I am trying to run HaplotypeCaller using GATK 2.7.4. I am getting the following error message:
ERROR: Argument with name 'mbq' isn't defined.

Here is my command line:
java -jar path_to_GATK/GenomeAnalysisTK.jar -T HaplotypeCaller -R path_to_reference.fasta -I reduced_01.bam -I reduced_02.bam -o combined_calls.vcf -stand_call_conf 30 -stand_emit_conf 30 -mbq 30

I am not sure what I am doing wrong. The algorithm is currently running as I just eliminated the -mbq parameter.

Regards,
Max

That's odd; I checked the code, that argument was present with the same name in version 2.7. Try using the long name --min_base_quality_score and see if that goes through. But there's no reason why this shouldn't work that I can think of.

Hi,

I've just tried to run it with the long name, but the result is the same. I am running the program on a computer cluster, maybe I need to report this to the admin.

Thanks for your help,
Max

Max, maybe try this with the latest version and see if the issue persists, just in case there was something off in the 2.7 version you're using.

Thanks, I've just done it using v. 3.1.1 and got the same error.

If you have a local machine available, you can try running on that and see if it's environment dependent...

... Thanks to the both of you. Just read Alex's answer. Sorry to have wasted your time, I read the script several times and still missed the typo.

Kind Regards,
Max
