[chimerax-users] alpha-fold error

[Moustafa, Ibrahim M.]

Dear all,

  I am trying to use alpha fold in ChimeraX but I get the following error during computing multiple sequence alignmenet step:

--------------------------------------------------------
 TypeError

<ipython-input-1-a242dc837c9a><https://localhost:8080/#> in multiple_seq_align(dbs)
    247       for i, result in enumerate(db_results):
    248         from alphafold.data import parsers
--> 249         msa, deletion_matrix, target_names = parsers.parse_stockholm(result['sto'])
    250         e_values_dict = parsers.parse_e_values_from_tblout(result['tbl'])
    251         e_values = [e_values_dict[t.split('/')[0]] for t in target_names]



TypeError: cannot unpack non-iterable Msa object


---------------------------------------------------------

  I followed the instructions of ChimeraX tutorial. I was able to use it successfully before, but not sure why I keep getting this error.

  Any idea what could be wrong?

I use ChimeraX version 1.3 (09-08-2021)

  Thanks for help
   Ibrahim
