David, thank you for your quick response. My replies are within the message

The following error message appears:

" icc -c -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -m64 -O2 -DBINTRAJ

> I think I was unclear in my question. Both tutorial A4 and the Users'
Manual do have examples of torsional restraints, but these examples are on
the angle measurement itself - not for the J-coupling. If I want to
include the Karplus equation coefficients do I simply add a line including
the rjcoef1 -> rjcoef3 variables?

Thank you!
