DEEPLC and MS2PIP doesnt work with multiple variable modifications

[yannic-chen]

Description of the bug

I have problems using MHCquant with multiple variable modifications.

The whole pipeline works when not specifying any modifciations.
With multiple modifcations, the pipeline only works when not including DEEPLC and MS2PIP.

Command used and terminal output

sudo nextflow run nf-core/mhcquant --input 'samplesheet.tsv' --outdir OUTDIR_HLA1_PTM --fasta 'human_20365_conts_validated_conversion.fasta' --use_deeplc --use_ms2pip -profile docker -r 2.5.0 --digest_mass_range '500:2500' --activation_method CID --prec_charge '1:4' --fdr_threshold 0.01 --fdr_level psm_level_fdrs --number_mods 3 --precursor_mass_tolerance 15 --fragment_mass_tolerance 0.03 --num_hits 1 --peptide_min_length 7 --peptide_max_length 25 --variable_mods 'Oxidation (M),Acetyl (Protein N-term),Cysteinyl (C)'

Hi @yannic-chen!
Thanks for reporting this issue. I could also reproduce it locally with a small testset. That reminds me of including tests for multiple variable or fixed modifications.

There won't be a fix for the deeplc and ms2pip scripts in the next release, since we want to use MS2Rescore to handle all kinds of configurations. So I just merged a PR that removed the deeplc and ms2pip modules, and implemented an ms2rescore module. Could you try using the dev branch with -r dev? That worked for me. So I'll give you a quick outline how to use it :

You can call e.g. ms2pip and deeplc via a new cli flag --feature_generators deeplc,ms2pip,... no need for use_deeplc and use_ms2pip anymore. Further feature generators you can read up in the ms2rescore doc.

If you only want psm_level_fdr then you can also specify a new cli flag --rescoring_engine mokapot instead of percolator (default), to get a handy ms2rescore report in the multiqc folder. peptide_level_fdrs are currently only applicable with percolator, since ms2rescore+mokapot currently only reports psm-level-fdr estimates.

Let me know if that works for you as well!

Hi @jonasscheid,
Thank you for the quick reply. I have followed your instruction, which led me to the following error:

  numpy.core._exceptions._ArrayMemoryError: Unable to allocate 4.42 TiB for an array with shape (964370, 629314) and data type object

Work dir:
  /home/chyannic/YC/test_mhcquant/work/02/34682d0057994344f573816d3feed8

Tip: view the complete command output by changing to the process work dir and entering the command `cat .command.out`

 -- Check '.nextflow.log' file for details 

I used the following command:
sudo nextflow run nf-core/mhcquant --input samplesheet_HLA1.tsv --outdir OUTDIR_HLA1_PTM_featureGenerators --fasta human_20365_conts_validated_conversion.fasta -profile docker -r dev --feature_generators deeplc,ms2pip --rescoring_engine mokapot --digest_mass_range '500:2500' --activation_method CID --prec_charge '1:4' --fdr_threshold 0.01 --fdr_level psm_level_fdrs --number_mods 3 --precursor_mass_tolerance 15 --fragment_mass_tolerance 0.03 --num_hits 1 --peptide_min_length 7 --peptide_max_length 25 --variable_mods 'Oxidation (M),Acetyl (Protein N-term),Cysteinyl (C)' -resume

The --feature_generators for ms2pip is by default "ms2pip": {"model": "HCD", "ms2_tolerance": 0.02}. How could I change the model to, for example "CID"?

Thank you for the good work.

That is a big input file you have right there! Looks like you ran out of memory. By default the MS2RESCORE module uses process_high, see specs here. Thats sufficient for most requests. If you need to allocate more, you can provide a custom config file that can be given via -c <name>.config containing e.g.

process { withName: 'MS2RESCORE'{ memory = 5500.GB } }

Fingers crossed that your setup has these specs

That is default ms2rescore, but in mhcquant the default is overwritten to Immuno-HCD, see your error message:

--ms2_tolerance 0.06 --ms2pip_model Immuno-HCD --rescoring_engine mokapot --feature_generators deeplc,ms2pip

You can use the model names of ms2pip documented on their github repo

Let me know if that helped. You can also use our Slack channel if you want to discuss in more depth.

Thanks for the quick response.

The input were 12 files which are less than 40GB in total.

I have redone the analysis now with only 2 input files, which now gives me another error.

Is it expected to require around 100x the total filesize in RAM for ms2rescore?

PS: it seems like the Slack channel you linked require specific e-mail address extension to work.

urllib.error.HTTPError: HTTP Error 403: Forbidden

Do you run offline?

Is it expected to require around 100x the total filesize in RAM for ms2rescore?

Normally not. Do you mind sharing your little test dataset such that I can run some tests on it?
is

PS: Apologies, maybe that one helps https://nf-co.re/join

EDIT: Can reproduce your error. Is a docker-related issue. I'll update you as soon as I have a fix

Fixed in the 2.6.0dev version by #302
