[gmx-users] Energy minimization of an UNKNOWN molecule.

2014-11-02 Thread Kalyanashis Jana
Dear all, I am trying to run a gromacs simulation using an .itp file of an unknown molecule ( non protein and DNA). I don't want to put the .itp file in a forcefield folder and I would like put it in my working directory. Can you please tell me, what is procedure to finish the energy minimization?

Thank you so much... I have tried to run the grompp step according to you. But it is showing "Fatal error: Syntax error - File A-T.itp, line 7 Last line read: '[ atomtypes ] ' Invalid order for directive atomtypes" I have attached the .itp file and .top file. Please kindly tell me, what to do now..
