AW: [gmx-users] Implicit Solvent

2010-01-21 Thread Hans HEINDL
Hola Deisy, I have used the implicit solvent which is built into mdrun-openmm. It works well: but there are some setbacks: 1. As far as I know it has only been tested with the amber 99 forcefield port for mdrun-openmm. (see http://chemistry.csulb.edu/ffamber/ ) and there is no easy way to do a pos

[gmx-users] define a new covalent bond in gromacs

2010-01-05 Thread Hans HEINDL
distance of the two atoms. (This was Peter Eastmans idea from Standford) How could we do that and where would be the best place to define (I presume the *.top file) the bond and where should the bond length and spring constant be defined? Thanks in advance Hans HEINDL University of Westminster
