Yes, I was looking into this as well. Though I was puzzled how my NOESY is
treated. I have got a gnoesyNhsqc experiment (in Varian terminology), that
is an HSQC step goes after noe transfer. Thus I have selected an
H_H[N].NOESY. My understanding is that the transfer should be set to
Hx->Hn->N->Hn, but there is no such an option in the Edit Experiment Types
table, is there?

Well, I guess I could go this way. Thank you.
