Training mvTCR on a single modality

[rahilgholami]

Thanks for this interesting tool!

As a unimodal baseline, I'm trying to train mvTCR using only RNA data and I set params_experiment = {'model_name': 'rna'}. Then when I run the run_model_selection line I get the following error KeyError: 'alpha_seq'. It seems the model is expecting TCR data which isn’t present in my dataset. I thought training on a single modality would work, as described in your paper.

Am I missing something in the setup? I would really appreciate any help.
Thank you!

Best wishes,
Rahil

Hi and thanks for your interest in mvTCR.

Could you try adding empty/dummy arrays named alpha_seq, beta_seq, alpha_len, beta_len to your adata.obsm field.
It should be an issue in the dataloader not checking for that case. The RNA only model wont use the tcr data.

Cheers
