CSD, FDAT --> MAC MIMIC or CHEM 3D



 dear netters:
 please tell me how I can use the file in FDAT format (got from CSD ) as
 input file to MAC MIMIC or CHEM3D.It seems to me that I need to change
 some "heading" of the FDAT file in some way (use a text editor) in
 order
 to adjust the NEW environment in MAC MIMIC or CHEM3D....but I don't know
 the "skill" !   help,help!
 cheers
