[DOCKTESTERS] BWA-Mem update

Thu Mar 23 05:58:49 EDT 2017

Hi,

Sorry if this is in your confluence page but I'm unable to access (could be as I'm outside OICR or that the default for your space is owner only).

Can you confirm if the CaVEMan calling was base on the BAM file that the original data was generated with or a one mapped with the new/recent mapping flow?

Also, the key information for determining if a call change is erroneous:

1. Is the variant is marked 'PASSED'.
2. What are the probabilities attached to the VCF record (should be in the info field)?

As previously stated we do expect a small variance in the results for the data processed at the beginning of the project and those at the end as well as some minor changes introduced when the normal-panel was moved from a web-service to a local file.

Regards,

Keiran

I finished one of the dockerized Sanger tests and upon verification there were just a few differences, but I'm not sure if they are normal or not.

Results:

Comparison for DO50398 using Sanger

---

Common: 171325

Extra: 3

    - Example: 14:20031258:G,8:43827158:A,X:61711363:C

Missing: 13

    - Example: 10:106963148:T,17:64794691:G,1:82709263:T

Because I'm a infrastructure architect my main reason for the test was to monitor resource utilization, so I wrote a wiki detailing my observations:

https://wiki.oicr.on.ca/display/~gmihaiescu/Dockerized+Sanger+workflow

I have there more Docker tests running, two of them run Sanger against the same donor (but using Vms with 8 cores because I want to see if the run time and resource utilization are constant), and a third test that is running DKFZ.

Cheers,
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
