AMBER: Hybridization in leap

Dear Amber Community,

I am working in Amber7 on a ligand that requires me to form more than 4
bonds on atoms that do not normally have this many bonds. Leap crashes
when I try to read in a pdb file with the corresponding library file
already loaded (FATAL ERROR in chirality.c, line 115). I have found that
bugfix.2 for Amber7 is supposed to fix this. When I try to apply the
patch, following the directions on the amber site I get the message shown
Why can the patch not be applied? Somebody please point me in the right
direction (I don't know UNIX very well).

Best Regards,


/amber7/src/leap/src/leap/ patch -c amber.c bugfix.2
Hmm... Looks like a new-style context diff to me...
The text leading up to this was:
