I am a very new user of VMD/MDFF. I tried to reproduce the simple
example in the mdff tutorial by using the windows version (vmd 1.9.1cuda
and namd2.9b2 under windows vista and also windows 7).
I found two problems:
1) location of the output files. Some files can be redirected to a
desired directory, but others cannot (i.e. mdff_template.namd). Where is
stored that information? is a symbolic link? How can I get that
information in a file in my directory of work?
2) When running namd2 (%namd2 adk-step1.namd > adk-step1.log)(pag 13 of
the tutorial) I got the following error: "Charm++ fatal error:
FATAL ERROR: Grid force potential file incorrectly formatted". I
followed the tutorial step by step. I am attaching the log file.

Can I have some help? Sorry if these questions are too basic.
