inputget error on alphafold structures

[shaharsu]

Hi,

I have a pqr file generated from an alphafold2 pdb. I am trying to generate an input file with the following command:

python3 /opt/spack/opt/spack/linux-rhel8-icelake/gcc-11.2.0/apbs-3.4.1-xj5ly7rbs6vfdrxfabur5cgzdox6szek/share/apbs/tools/manip/inputgen.py --method=auto tmp/tmp-elec/AF2.pqr

The command exits with the following error:

Forcing a sequential calculation

The same command works fine for pdb's obtained directly from the pdb website (e.g. 1UBQ). I'm attaching the initial AF2 pdb and the resulting pqr file.

Sorry - guess upload didn't work before - here it is.

Ha, was JUST about to ask. Thanks! I'll have a look as soon as I can.

Thanks very much,
