[DOCKTESTERS] BWA-Mem update

Mon Apr 10 12:33:16 EDT 2017

Hi George,

We should be able to provide you with a final answer on this tomorrow by the latest :)
Would that be OK for you?

You could already download the relevant unaligned bam files as this will anyhow take some time.
Miguel and I have been running on donor DO51057 and you can find GNOS IDs for the unaligned files in the attached JSON file.
Get all of the bams defined under the “unaligned_bams” headers (there will be 2 of these headers in the JSON, one for the normal and one for the tumor).

The BWA-Mem docker is internally set to run on 8 cores, so using a large VM is unlikely to affect run-time.

Best wishes,
Jonas

Hi,

I would like to run the BWA-mem dockerized workflow in the Collaboratory environment, but I need some help in order to do this:

  *   A ready-to-run script or instructions
  *   The input files: single file or multiple files, whatever the script needs as an input
  *   The donor ID, preferably the same donor that was already used in order to prove the reproducibility of the results

I can start the workflow on a large VM in order to speed up the result.

Also, I'm currently running the DKFZ workflow on DO50398 because I've already ran Sanger on it, and I want to compare the run times for the two workflows on the same data set.

Thank you,
George

Thanks Jonas for this information.

I hope that someone here can provide us with some suggestion on what to try next. Perhaps the version issue that Jonas point out is the key.

I just want to add that, as I told Jonas earlier, my own tests using the new split BAM files also gave 3% mismatches.

Best regards

Miguel

Hi all,

A brief update on the BWA-Mem docker tests.
I prepared normal + tumor lane-level unaligned bams for DO503011 and ran the BWA-Mem workflow for normal and tumor seperately.
Doing the comparison however, I am still getting 3% of reads that are aligned differently (see below for a few examples).
However, when checking the headers of the original and newly mapped bam files (attached) I noticed that the original is mapped using a different version of BWA and SeqWare.
I’m hoping the mapping differences can be ascribed to this.

Is there a list available somewhere detailing which samples were mapped using which versions?
That way we could select a relevant test sample without having to sort through the headers of all different bams.

Best wishes,
Jonas
