[gmx-users] about stretch protein using gromacs 4.0 umbrella options

[mhviet at ifpan.edu.pl]

Hi all,
  I am trying to stretch protein using gromacs 4.0 umbrella options.
(please see mdp file in attachment).
 This is quite large 136 amino acids protein which I want to stretch
completely using sets of mdp files with 250000 numbers of steps.  To
perform these simulations I have to be able to continue my MD simulation
after each successful run. Could you give me advice which options I
should add or change to perform these simulations in a correct way.

Thanks a lot in advance
