I'm beginner charmm program.
I generated a POPC only with CHARMM-GUI membrane builder and downloaded the setup files.
Now I am trying to understand the procedure to modify the input files.
As first step, charmm -i step3_packing.inp
It occurs error, I don't know why this error occurring so
I can't solve this problem.
Am I supposed to set the parameters in the step3_nlipids_lower.prm file?
set nchl1bot = 0 (:original) -> set nchl1bot = 1
How can I solve this error?
(And I attach error code)
