I am interested in making a scan along an internal coordinates that is dihedral angle between planes I-J-K and K-L-M ("encoded coordinate type" 6 in FF manual, page 252). When I tried to make a scan along such a coordinate FF crashed without any specific error, just only this:
ADDRESS 0x094199BA HAS INITIATED PROGRAM ABORT BECAUSE OF FATAL ERROR(S)
The error for sure has to do with setting up that coordinate as when I replaced the coordinate by another one (a standard dihedral angle) I didn't get any error.
I wonder if someone has ever successfully used/defined coord 6? Could the problem relate to the use of DLC coordinates (I have in my input options DLC=.T. and AUTO=.T.), I mean, if DLC is compatible with that internal coordinate?
