Hmm, this is really odd, but in our deployment of BioPack these the sequences you are mentioning have been replaced with the following statement (or similar):
/* gnoesyChsqc_NC for Heterodimer Studies
has been temporarily removed
for pulse sequence revision
*/
I've found the following sequences in the library:
CNfiltocsy.c gnoesyChsqc_CNfilt.c
gChmqcnoesy_CNfilt.c gnoesyNhsqc_CNfilt.c
Also, according to the Varian/Agilent user library (you'll have to find the biopack page there and register first) the noesy-hsqc sequences were in Dec 2009.
