[gmx-users] how to use gmx rdf to compute the RDF between the COMs of molecules (more than 3)

2016-03-14 Thread LIANG Xujun
Dear GROMACS users, Recently, I am trying to compute the RDF between the COMs of five molecules using gmx rdf. The detailed command I wrote is as follows: gmx rdf -f *.xtc -s *.tpr -n *.ndx -b * -e * -rdf mol_com -norm -o rdf.xvg I've made an index file of a group formed by the five

Dear Eric. I am now also calculating the angle between normal vector of plane 1 and com vector of plane 1 and plane 2. I also use the following command you used in the mail (with small modifications). gmx gangle -f file.trr -s file.tpr -n file.ndx -g1 plane -group1 'z 0 to 1 and group

Dear GROMACS users, I am now using gromacs 5.0.4 to calculate the angle between the normal vector of a plane 1 and the COM (center of mass) vector of plane 1 and plane 2, I used the following command: gmx gangle -f *.xtc -s *.tpr -n *.ndx -g1 plane -group1 plane 1 (I tried to use this command

of a plane Hi, Can't you get the angle you want by subtracting the one you have from 90? Mark On 15/04/2015 5:58 pm, LIANG Xujun xujun.li...@cea.fr wrote: Dear GROMACS users, I am now using gromacs 5.0.4 to calculate the angle between the normal vector of a plane 1 and the COM (center

Hello all, I have one question: I would like to compute the angle between the normal vector of plane 1 and the com vector of plane 1 and plane 2 using gmx_mpi gangle (version 5.0.4). The command is as follows: gmx_mpi gangle -f xtc -s tpr -n ndx -g1 plane -group1 -g2 vector
