[DOCKTESTERS] Thanks!

Hi Keiran,

Can you please comment on this, i.e., comparison between alignment done lane by lane v.s. done with all lanes mixed?

Basically, we are trying to prepare input BAMs for testing PCAWG BWA MEM workflow. The starting point is the aligned BAM because we don't have the unaligned lane BAM any more. The key point here is: should input BAM organized by lanes, one lane one BAM? Or just one BAM containing all lanes?

Thanks,
Junjun

Hi Junjun

About the unaligned BAM files, in fact I do have them for the two test I've ran. I could put them available for George but I think he could just as well produce them on site, since he might have to do that anyway. But we can always explore that option, though right now I don't know of a simple way to move these files around.

About the number of lanes let me just say good grief! This is the first time I hear about it. So if I understand you correctly I need to:

1- Download the metadata for the BAM file
2- Determine the read_groups
3- Split the BAM file according to these read_groups
4- Unalign these BAM files and produce header files with different lanes
5- Run BWA-Mem
6- Compare collectively the reads from these BAM files with the original BAM

Could you please confirm that this is the case? Is this consistent with the 3% mismatches? A similar percentage was found in the HCC1143, could this be the reason for that as well? Also I asked Keiran about these headers and he said there where OK. If you could please confirm that I need to do this extended process I'd be grateful, because its quite involved and there are concepts here I'm not familiar with.

Regards

Miguel

Hi Miguel,

I thought you kept the unaligned sequence you prepared for the testing.

Following your link about preparing unaligned input, I found this: https://github.com/mikisvaz/PCAWG-Docker-Test/blob/master/bin/prepare_unaligned.sh#L16-L35, which actually could explain the high mismatch rate.

When BWA MEM workflow runs, the alignments are done one lane level BAM at a time, then merge the aligned BAM later: https://github.com/ICGC-TCGA-PanCancer/Seqware-BWA-Workflow/blob/develop/src/main/java/com/github/seqware/WorkflowClient.java#L201

I see the script prepare_unaligned.sh always generates one read group (i.e., lane) for normal or tumour, no matter how many read groups (lanes) in the aligned BAMs. This has big impact on the alignment result when lanes are aligned independently comparing aligned altogether.

The PCAWG Sequence Submission SOP has a step to prepare unaligned BAM, but it only works when the input is single lane BAM file:  https://wiki.oicr.on.ca/display/PANCANCER/PCAWG+%28a.k.a.+PCAP+or+PAWG%29+Sequence+Submission+SOP+-+v1.0#PCAWG(a.k.a.PCAPorPAWG)SequenceSubmissionSOP-v1.0-a)FollowthisifyoustartfromsinglelaneBAMfiles

So, I think in order to perform testing alignment workflow properly, we will need to prepare lane level unaligned BAM (one lane one BAM) as inputs. For example, this aligned BAM: https://gtrepo-ebi.annailabs.com/cghub/metadata/analysisFull/c9fa1c22-6432-4851-af67-30f4b4812c63, it has 7 read groups (search for read_group). It needs to be converted to 7 individual lane level BAM files.

Not sure whether it's the best way to do BAM splitting, but here is someone's Python code to do it: https://gist.github.com/seandavi/2014542

Hope this helps,
Junjun

Hi George,

The analigned BAM files are not available as far as I know, rather you must unalign the final BAM files, the normal ones you get from ICGC or GNOS. This process is also in my scripts, as you see here:

https://github.com/mikisvaz/PCAWG-Docker-Test/blob/master/bin/run_batch.sh#L32

About the steps in the workflows, I don't know them myself. I think you'll need to ask the developers, and not all workflows use the same underlying workflow enactment tool. Not an easy answer

Junjun told me this would provide value to the testing process, so I would like to kick off a test of the BWA_mem docker.
Can somebody provide some quick instructions and the location of the unaligned BAM files that were used already?

Also, do we have somewhere the steps involved in each workflow, so I can get an idea of how far they are while running?
For example, s58_cgpPindel_pin2vcf_95 is three steps from finish, or 50 steps from finish…

Thank you,
George

Hi Miguel,

I've started the test by running "bin/run_test.sh Sanger DO50398", so I guess with just one workflow running it should complete faster than two weeks.

I think it still should take a long time. My scripts will run one workflow after another.

Because I'm running in Collaboratory I've changed the "get_icgc_donor.sh" script to use a docker container that has the icgc client inside and pull data from Collaboratory. There is no "bam.bas" file downloaded, just a ".bam" and a ".bam.bai" files, not sure if this is an issue.

I wondered the same thing first time I did this, but this file is produced by the pipeline. There was some problem with this that was dealt with by the developers and updated in the docker. So I think you won't have a problem

By looking at the "bin/compare_result_type.sh" it looks like it's using the gnos client to pull down the existing VCF files for comparison reasons, but I think we store those files in Collaboratory as well, so I'll work with Junjun to adapt the script for this.

Let me know if you need any help

I think I initially tried to run the DKFZ workflow, but it complained about having to run Delly first, so I abandoned this for now.

Yes, if you look at the run_batch.sh you will see that when using DKFZ it will always run Delly first. Delly prepares some files the the  DKFZ file needs, namely related to copy number I believe.

I'll set up a new VM and run the "run_batch.sh" on the DO52140 donor.

Remember that you will need to add the relevant has-keys for the different files in the etc/donor_files.csv. Its a bit tedious right now. You need to go to the ICGC DCC and find these codes manually for the files you need. Ask me if you need help. Once you have all you can run all the workflows for that donor and evaluate results.

Hi George,

The Sanger workflow is very lengthy, it takes about two weeks in my tests.

About correctness, my scripts also cover that part, if you are not using them they might still help you to clarify how we do it. The idea is to take each of the output files produced: SNV_MNV, Indel, SV, and CNV, for both germline and somatic and compare it with the result uploaded to GNOS (not all pipelines produce all files). This is the relevant part in the run_batch.sh script:

https://github.com/mikisvaz/PCAWG-Docker-Test/blob/master/bin/run_batch.sh#L42-L46

The bin/compare_result_type.sh script will take care of downloading the correct file from GNOS and running the comparison. The comparison itself is simple since all files are VCFs, it consists in taking out the variants in terms of chromosome, position, reference and alternative allele and measuring the overlaps.

https://github.com/mikisvaz/PCAWG-Docker-Test/blob/master/bin/compare_result_type.sh

About which donors to test, DO52140 is one Jonas and I have both tested and could be interesting to get a third opinion. Also, any other donor could be interesting to see if something new comes up. I'm not sure which options is best.

Hi,

I've started Sanger on DO50398 and it's been running for more than 24 hours, currently at "Workflow step succeeded: s58_bbAllele_merge_59"

I just started a second run on a different VM on same donor, just to compare run times.
The VM used has 8 cores, 48 GB of RAM and 1.1 TB disk and I'll send some monitoring graphs when it finishes the workflow, but I have no idea how to check its correctness.

Give me a list of donors and what workflows you want me to run and I'll try to schedule them tomorrow.

Hi George,

Yup, I've been running the PCAWG dockers mainly using Miguel's set of scripts.
Give them a go and if you run into issues, just let us know!

Hi Junjun,

I think Jonas has been using my scripts to run some of the tests, maybe George could try them as well, it should be very easy for him to try the Sanger, Delly+DKFZ, BWA-Mem, and the BiasFilter.

https://github.com/mikisvaz/PCAWG-Docker-Test

He would just need to update the tokens for DACO access and the scripts will take care of downloading the BAM files, running the workflows and evaluating the result.

The documentation there is reasonably updated, but if this sounds good then perhaps he could contact me and I could walk him through the details.

Best regards

Miguel
