I have installed RNA-SeQC on our cluster and have been trying to run a number of jobs for RNA-SeQC (version 1.18) on 5-6 Gb BAM files of human RNA-seq data.
Info about the BAM files: human paired-end sequences, aligned to hg38 build genome using STAR, read groups added, sorted and indexed.
The command file for RNA-SeQC is generally:
/share/apps/jdk1.7.0_71/bin/java -Xmx60g -jar /user/tools/RNA-SeQC/RNA-SeQC_v1.1.8.jar \ -bwa /user/bwa-0.7.10/bwa -BWArRNA \ /user/ref_genome/hg38_ucsc/Homo_sapiens/UCSC/hg38/Sequence/WholeGenomeFasta/rRNA.gtf -t \ /user/ref_genome/hg38_ucsc/Homo_sapiens/UCSC/hg38/Annotation/Archives/archive-2015-08-14-08-18-15/Genes/genes.gtf -r \ /user/ref_genome/hg38_ucsc/Homo_sapiens/UCSC/hg38/Sequence/WholeGenomeFasta/genome.fa -s \ /user/bam/bam_samples.txt -o /user/bam/RNA-SeQC
The bam_samples.txt only includes one BAM now as I was having the same error with many so I am trying to get it sorted just to work with one for now.
From the output it looks like the job is working fine to a certain stage and then I am getting memory errors. I have given the cluster job memory ranging from 16Gb to 128Gb with no luck at all.
The error I am getting is:

Apologies for the length of the post but I wanted to get as much useful information in place.
If anyone has any suggestions or advice it would be greatly appreciated!
