Hello users
I am using gromacs 3.3 with 43a1 force field.
My question is that if i run a simulation say for 50ns , Then if i
carried out another md after this one than its time should start from
ahead of 50 and not again from the beginning. but in my case everytime
the time starts from the beginning.
It's doing this because you're telling it to do this. :-)
I know its a very basic question which i should not ask from the
intelligentsia but this is irritating me from quiet a long time.
so please tell me if this is a usual behaviour or some mistake is there
in the input file
You're using grompp for restarts, which is fine, but you need to be
aware that there are heaps of input file options, some of which have
default values. See section 7.3.3 of the manual. Easier than reworking
your .mdp file all the time is to use tpbconv for restarts, as Alan
suggested. See man tpbconv.
After every run i am using the output gro file as an input for the next run
Hopefully it's not the only input! You only need a structure file for
the atom names (or so)... everything else comes from trajectory and
energy files.
