Hello,
More specification is required (i.e. 15N-hsqc or 13C-hsqc, gNhsqc gChsqc,
respectively) and if it's using the Rance-Kay (on brukers known as
echo-antiecho) style of fid acquisition/sorting.
The 15N-hsqcs (gNhsqc) all use the sensitivity-enhanced acquisition
method while it is an option in the gChsqc sequence. There are several
macros available to resort the data before processing. NMRpipe for example has
the resorting built in to the FID conversion from varian to nmrpipe format.
