Running GATK, keep receiving errors.

[prs321]

I have tried to run GATK 2 different ways on the mason server. These are the two ways I tried, and I still keep getting errors.

1. java -jar GenomeAnalysisTK-2.6-4-g3e5ff60/GenomeAnalysisTK.jar --help

Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

2. java -Xmx2g -jar GenomeAnalysisTK-2.6-4-g3e5ff60/GenomeAnalysisTK.jar --help

#
Aborted (core dumped)




How do I get this to work? I also have tried from my local computer but it still doesnt seem to work. Here are some of the ways I tried it from my local computer.




1. java -Xmx2g -jar GenomeAnalysisTK-2.6-4-g3e5ff60/GenomeAnalysisTK.jar --help

I get the same error without the -Xmx2g thingy.

I think you're using the wrong version of java.

http://www.broadinstitute.org/gatk/g...rticle?id=2846

The bottom of that page gives details about the version of Java required and the error that is spit out when the version is wrong.

I should have noted before...

I am using the correct version of java.

I typed in java --version both on my local computer and the server. Both versions were above version 1.6.
