Hi,

when I'm running the DPP I get an error. I think it is because the command '.exec5886755893230759761' is removed from the temp folder while it is being used. I have tried with the '-keepIntermediates' option but the command is still being deleted.

Any suggestions to avoid it?

The error (I have the complete output if needed):

Is there any rule of thumb for allocating memory through "bsub" for running DataProcessingPipeline per bam file or per number of reads ?

Thanks

Dear all , I am using Queue and DataProcessingPipeline.scala ( from https://github.com/broadgsa/gatk/blob/master/public/scala/qscript/org/broadinstitute/sting/queue/qscripts/DataProcessingPipeline.scala ) to process my bam file . The input is a sample level bam file which has been processed by BWA aligned , Samtools sampe and Picard merge and duplicate removed . The output bam file (~200GB/sample ) is much larger than the input bam file (~80GB/sample ) . I want to know what information was added into the bam file ? Thanks a lot .My Queue version is Queue-2.1-10 . My script :

java \ -Xmx4g \ -Djava.io.tmpdir=../tmp/ \ -jar ./Queue-2.1-10/Queue.jar \ -S ./DataProcessingPipeline.scala \ -i input.bam \ -R /db/human_g1k_v37.fasta \ -D /db//dbSnp_b137.vcf \ -run

I had a question that, while it might be more appropriate for a BWA or seqanswers audience, I noticed something in the GATK's "Data Processing Pipeline" under "Methods and Workflows" that made me wonder. The pipeline is described here and there's a nice flowchart as well: http://www.broadinstitute.org/gatk/guide/topic?name=methods-and-workflows#41

The process describes a BAM of reads that are either not aligned or aligned by some process you don't want to use, so the first step seems to be Picard's RevertSam and then a realignment with BWA. I'm wondering why the process described by this GATK document splits it into per-lane BAM files. There doesn't seem to be any process done at the per-lane level other than BWA alignment. I have two guesses.. the first was to allow more parallelization at that step.

But my second guess is that perhaps BWA doesn't play nice with read groups when reading reads from BAM input files. If that is true, that would explain why I'm having trouble with BAM (a single sample, multiple lanes, merged into one file) -> BWA -> realigned-BAM -> GATK (either UnifiedGenotyper or RealignerTargetCreator, etc)--somewhere along the way, read groups are getting lost. So my guess is that the above-described pipeline splits it per-lane so it can manually respecify read groups all over again to BWA?

Is that other people's experience as well?

Also, the Methods and Workflows page describes a Queue script, but there's no link or anything to the actual Queue script. Anyone know where to find it?
