[gmx-users] orca question and LA

[Micha Ben Achim Kunze]

Hey there,

my last mail got stuck as it was a bit too large it seems. As I wrote 
earlier there should be NO coordinates in the infofile... It looks like 
you have a problem with gmx not preparing a correct .inp file which 
should include keywords from the infofile, the coordinates of the 
QMsubsystem and pointcharges (depending on the method you use). Are you 
sure everything is compiled correct and that you specified your virtual 
atoms correctly for your force field (and with correct 
positions/constrains)? Have a look if gmx actually creates an .inp file 
and if yes what it includes.

Again, you should go through Gerrit's tutorials, they should get you 
going. There are also instructions on how to set up LAs for different 
force fields.

Cheers,
Micha
