[gmx-users] Get some specific frames of traj

[Shima Arasteh]

I tried the tpr file for -s, but doesn't make difference. 


g_select -s npt_6.gro -f md_0_1.trr -select 'resname SOL and within 0.01 
of (3.6, 3.6, 6.3)' -seltype res_com -selrpos res_com -os

Would you please give me suggestions? I found some resemble commands in mailing list but didn't find the problem with my command.

Thanks in advance.


Sincerely,
Shima

g_select -select 'help all' provides a huge amount of information.  Have you 
tried passing a .tpr file to -s instead?  Are your units right?  It would seem 
your box is very big.
