Dear Tsjerk, My system contains CG (Martini): POPC bilayer, 21 AA peptide, water and ions.
I realize that for all-atom the topology file should not contain details for water and ions. As a test while trying to understand and get familiarized with backward. As of now I am trying to convert CG peptide only to all-atom. I am using the following command: ./initram.sh -f protein.gro -p topol.top -from martini -po backmapped.top -to gromos54a7 (I obtained the topol.top file for the peptide by using: pdb2gmx -f peptide.pdb -o peptide.gro -p, selecting ff charmm and TIP3P water) The script is giving me the following error: Traceback (most recent call last): File "/shared/maylab/shivi/fhv/inverse_cg/try1/backward.py", line 644, in ? struc = Structure(options["-f"].value,strict=options["-strict"].value) File "/shared/maylab/shivi/fhv/inverse_cg/try1/backward.py", line 388, in __init__ if not all(chain): NameError: global name 'all' is not defined Could you please help.
