The Varian gHSQC data I have seen is echo-antiecho. If you process it as
you would for States, you will get mirror images.
You can read some details about how the data are organized and how the
processing is done on our web site.

and for echo-antiecho data:

> Subject: F1 detection for Varian's gHSQC sequence
Hi everybody,
Does anyone know the F1 quad detection method used in Varian's gHSQC
pulse sequence? Specifically, I would like to make sure that my
SpinWorks software can process it properly, but the sample data that I
have processes with an F1 mirror image problem. The standard Varian
HSQC sequence (which
uses gradients) uses the standard States method, as does gTOCSY. The
gHSQC sequence, however, seems different. The "phase" parameter in the
procpar file is 1 5, as opposed to 1 2 for a
normal States data set.
Does anyone know what is going on here?
Thanks in advance!
