Thanks,

 Hello,

 This email is directed mainly to Alan, who created Acpype.

 I've noticed that Acpype has assigned dihedral constants as 0.65084 for
 many dihedrals of the form X -c3-n4-X, X -c3-c3-X, and others, in my
 generated GROMACS .itp files.  These dihedrals have values of 1.400 in the
 amber 99sb .dat file, which should have instead given 1.4*4.184 = 5.858 for
 the result.

 Most other dihedrals I've checked have behaved normally and their values
 correspond to what would be expected - except for dihedrals with values of
 0.65084 in the .itp files.

 Any ideas about what's going on?

 Thanks for your time.

 Kyle Greenway
