Chikaterasu Martini version

Bash script to automate setup of multiple identical MD simulations. MD parameters are for the martini 2.2 forcefield.

Usage

  1. Prepare the topology using the martinize python2.7 script (see folder martinize-script).
  2. Prepare the coarse-grained protein structure file in ./gromacs/coord/
  3. Run: ./chikaterasu-martini 1 [This will test if topology can be generated correctly in gromacs]
  4. Run: ./chikaterasu-martini 2 [This will test if solvation worked fine]
  5. Run: ./chikaterasu-martini 3 [This will test if counterions were correctly added (not yet implemented)]
  6. Run: ./chikaterasu-martini 4 [This will test if a short equilibration MD trajectory can be obtained in gromacs]
  7. Run: ./chikaterasu-martini 0 [This will assume everything so far went well and go to the actual production MD run]

MD parameters are adjusted by editing the gromacs .mdp files in the chika_mdp directory.
