Dear All
I'm trying to use the procedure described into this post : Constraint
warning with AMBER PDB file
First of all, I dumped the prmtop file into a psf file.
Then I modified the molecule name and changed the prmtop with the dumped psf
in the input file. Then, I tryed to run a QM/MM MD with constraints.
However I got this error:
*** Missing critical ForceField parameters! Abort.. ***
The prmtop file works well, then I think that I have to specify somithing
during the dumping procedure
Now I'm using this command:
&DUMP_PSF
&EACH
MD 1
&END EACH
FILENAME =aro.psf
&END DUMP_PSF
Can you help me?
Thanks
Jacopo
