Thank you for your response. Yes my input to `trjconv -s` has my system in such way that I can make all my desired calculations (as far as I can see in VMD). Sincerely Max. > On Jan 25, 2019, at 22:11, Mark Abraham wrote: > > Hi, > > What property do you want to make true? Does your

Finally, I visualized the data in the output file of -otilt (tilt_TMC1CA.xvg) using xmgrace with the command: xmgrace -nxy tilt_TMC1CA.xvg I read again the documentation of gmx helixorient and if I understood well, the values of the tilt angle of the helix axis to the membrane plan are

Hi, Roland, Thank you for your response. If the GT2 GPU won't give much acceleration, I'm not sure that it's worth to fix the timing issue in beignet, since it's deprecated. Not much sense in trying to make a deprecated driver work so an ineffective GPU can be used. I'll be testing a GTX 1050Ti

Re: [gmx-users] "Too many LINCS warnings" in a minimization after solvation with coarse-grained waters

Dear All, (hope this message can be put under the original thread) I solved this problem. The reason is, I was trying to fill the system with water then minimise it, which is not good. The better way is, prepare a waterbox that is even larger than the system box. Then minimise that water

pdb2gmx isn't acceptable for any molecule. Only for proteins and DNA-RNA. β-cyclodextrin is present in atb.uq.edu.au in many variants for force field G54A7FF Or it is quit simple to build β-CD with glycan builder and modeller from charrm-gui.org (7 times connect α glucose with 1-4 link). One

Hi. I know you can compute distances of mass center's of two atom groups using `g_dist` command. But I cannot find command that does the same in Gromacs version 5.* I know `gmx distance`, but it calculates pairwise distances in one selection. And `gmx pairdist` which calculates only min or max
