I am new to Gromacs. I have generated pdb and psf for my system. And I want to convert it to .top file. I have tried "topo writegmxtop" in vmd using "topo writegmxtop my.top [list parameterfile1.prm]". The angles and dihedrals are correct, but the "type" column in atoms directive is same as the "atom" column (I mean C1, C2 are the labels for the "atom", but it should be same label as the one in the forcefiled in the "type" column ,but it is not in my case). The atom type is already in my psf file and there is no errors and warnings during the conversion.
Then tried Parmed with following commands:
import parmed as pmd
But my linux system is stuck (mouse is locked and changed to cross-shape,no error messages are reported). And there is no output after 1 hour(I have about 10000 atoms). And I am able to run the tests in the test folder before I used above commands.
My questions are :
(1)Is it a right results from VMD?
(2)What is wrong with my usage of Parmed?
(3)Is there other tool to convert psf to top?
Can any one help me out?
