[gmx-users] Question on running gmx trjconv without 2 prompts

[Lei Qian]

Dear users,

Could I ask: how to run gmx trjconv without 2 prompts?
I select 'Protein' to center, and 'System' to output.

I put indexes of 'Protein' and 'System' into 1 .ndx file, add -n
Protein_System.ndx to gmx trjconv command, however, Gromacs cannot do the
selection automatically and asked me to choose from 'Protein' or 'System'.
Thanks!
Lei
