[Chimera-users] Problem during Residue interaction network generation

Try using trjconv with the -skip option to write out a much smaller trajectory file (20 frames or less, see: gmx trjconv — GROMACS 2018.3 documentation <http://manual.gromacs.org/documentation/2018.3/onlinehelp/gmx-trjconv.html>). Is that slow or fast? If it’s slow, the file should be small enough that you can mail it to me directly (not the list!) along with your topology file, and then maybe I can reproduce the issue. Also, what version of Cytoscape are you using?

Do exactly what you were doing before, but instead of using your trajectory, use the attached multi-MODEL PDB file for the trajectory (when you start the MD Movie tool, choose “PDB” as the trajectory format and “single file” within that format). Does computing a residue interaction network using that trajectory also get hung up?

After this step, when I click "apply" for displaying the interaction network in Cytoscape, it often shows "Importing Residue Network from Chimera", sometimes "getting data for attribute secondarystructure" and sometimes "getting data for attribute ishelix". Even after I wait for half a day, the message continues to show and I am not able to work on Cytoscape.
