Hi,
In the ptraj hbond section of the AMBER 8 manual (top of page 212), it says:
"The default is no angle cutoff and a distance of 3.5 angstroms."
However, it looks like the actual defaults are 120 degrees and 3.0
Angstroms. I think the relevant lines are ptraj/actions.c 4726-4730:
/*
* distance and angle cutoff
*/
hbondInfo->distanceCutoff =
argumentStackKeyToFloat(argumentStackPointer, "distance", 3.0);
hbondInfo->angleCutoff =
argumentStackKeyToFloat(argumentStackPointer, "angle", 120.0);
And the output files agree with that when you use the details. I don't
have AMBER 9 to check the source code, but the AMBER 9 manual also
says "the default is no angle cutoff and a distance of 3.5 angstroms"
(this time on page 263).
What are the default values supposed to be?
Thanks,
-michael
