pVACseq related error

[SreeChai]

Hi
I ran the pipeline's latest version on a file on which it had run successfully over 5 yrs ago.
The steps unto the fusion peptide generation were completed,
this is the subsequent error:

Error executing process > 'pVACseq (Sample25)'

Caused by:
Process pVACseq (Sample25) terminated with an error exit status (1)

Command executed:

Command error:
INFO: Converting SIF file to temporary sandbox...
IEDB MHC I executable path doesn't exist /opt/iedb/mhc_i/src/predict_binding.py

the path for the script is /Tools/neoAg_nextNeoPi/resources/databases/iedb/mhc_i/predict_binding.py
Where do I have to update this?

thanks in advance
