[gmx-users] martinize.py: option for partly have elastic network on partly in the protein

[shivangi nangia]

Dear gmx-users,

I wish to coarse grain a  peptide, while keeping only the N-terminal
flexible (elastic network off) and rest protein elastic on.

Is there any option/flag to selectively pick residues on which I do not
want elastic network on.

Kindly suggest.

Thanks in advance,
sxn
