Dear Justin,

Thank you very much. I followed the same spirit and add forcefield.doc.
However, it did not work until changing all ffPACE_1.5.rtp .ddb .....etc
files into aminoacids.rpt .ddb ..... GROMACS seems to recognize only the
name "aminoacids". Also, don't forget to change the ffPACE1.5.itp to
*forcefield.itp* instead of aminoacids.itp.

Regards,
Simon
