Good morning,

I am starting with CG in Gromacs using Votca, is it possible to use 
Charmm36-forcefield instead of OPLSA?

I have created a system of 8 asphaltenes in heptane, I have already run it in 
atomistic without any problem. Now I have created .xml files of heptane and 
Asphaltene, I have run the code

csg_map --top topol.tpr --trj confout.gro --cg "heptane.xml;a08.xml" --out 
conf_cg.gro  for mapping but I recieve as error: molecule 1:a08:C does not 
exist, I don't understand why because I have already declarated a08 in topology 
and everywhere. Maybe I am not doing well different steps for coarse grain, 
could anyone explain me?

Kind regards
Plácido
