Hi Gromacs users ,
as per the link given on gromacs website...
Introduction to Molecular Dynamics Simulations and
Analysis<http://nmr.chem.uu.nl/%7Etsjerk/course/molmod/>- Tutorial for
performing and analyzing simulations of proteins. Includes
examples of many of the gromacs analysis tools and addresses a number of
issues that are commonly raised on the GROMACS user list. This tutorial
uses GROMACS version 3.3.1 (Tsjerk A. Wassenaar).
editconf -f protein-EM-vacuum.pdb -o protein-PBC.gro -bt dodecahedron -d
1.0
mdp file parameter are as follow ,
coulombtype = Reaction-Field
rcoulomb = 1.4
epsilon_rf = 78
epsilon_r = 1
vdw-type = Cut-off
rvdw = 1.4
so my query is ..
As mention in manual ...
(Page no 14 manual 4.5.4 I am using the Gromacs 4.5.4 )
*This means that the length of each box vector must exceed the length of
the macromolecule in the
direction of that edge plus two times the cut-off radius Rc *.
*In the tutorial -d 1.0 is less than 1.4 .*..
I noticed that manual version and tutorial gromacs version are different
...
But it raise a lot of confusion for new users like me..
1. Is the -d .. should be equal or more than cutt off ???
or
Is the -d .. should be equal or more than cutt-off??
