Hi Raag, Chimera is not really efficient with big files (many atoms), but you can try a few of these: 1) run on a machine with lots of ram 2) avoid as many atoms as possible 3) match as few atoms as possible 4) avoid rendering the file 5) if you want to have it rendered, disable smart display (Chimera pref > New Molecules > Smart Initial Display) Ad 4) Write a command line chimera script (run with "chimera --nogui script.cmd"), for example: -----script.cmd------ open file1.gro file2.pdb match #0:res #1:res write format pdb relative 1 0 aligned.pdb --------------------- Best, ------------------------------------------------------ Dr. Matej Repic Ecole Polytechnique Fédérale de Lausanne Laboratory of Computational Chemistry and Biochemistry SB - ISIC LCBC BCH 4108 CH - 1015 Lausanne ------------------------------------------------------ On 10/9/15, 08:54, "chimera-users-bounces@cgl.ucsf.edu on behalf of Raag Saluja" <chimera-users-bounces@cgl.ucsf.edu on behalf of saluja.raag@gmail.com> wrote:
Hi!
Chimera crashes when I try to open a .gro file (created through GROMACS).
I wanted to open the .gro file and then superimpose it on a .pdb file.
Can you please guide? Thank you!
Regards, Raag
