GROMACS version: 2019.2
GROMACS modification: No
I am trying to create a Gromacs index using
gmx make_ndx -f …/inici/AAAKTPVIV_HLA_A_02_01.pdb -o index.ndx
and I want to include chains A and C to the index
I just tried to do it using the following commands
but it fails all the time
Found 0 atoms with chain identifier A (idem for C)
Group is empty
Of course, I checked that my PDB has chains A and C (it also has B)
Can any want tell me how to deal with it?
Thanks in advance!
