I used BWA on a local galaxy installation (Ubuntu 12.10) to generate an alignment of my FastQ reads. Now I am trying to use GATK Unified Genotyper with my own reference sequence. The first time I ran it, I had forgotten to edit env.sh to show the path to the GATK .jar file. After I fixed that, the next time I tried to run it I got the error shown below. If I understand this correctly, it already tried to create a tmp file from the first run and now is unable to continue until I delete it. However, I cannot locate the file. 1) Am I correct in my understanding of the error? 2) How do I delete the file to clear the error? Thanks everyone!
