Hi Navnett,


gmx select will be your friend.


At the bottom of

http://manual.gromacs.org/documentation/current/onlinehelp/selections.html

you'll find some example commands. Something along the lines of

   gmx select -select 'name CA and resid > 149 and resid < 211'

should work.


It's a very powerful syntax and I figured for me it was very much worth the effort reading through that documentation.


Best,

Chrsitian
