Siemens: Where is the non water-suppressed spectra?

Hi,

For Siemens PRESS I’m trying to get the water reference spectra but don’t know where to find it. Is this stored in the same twix (.dat) or dicom file as the metabolite spectra?

In the exam card I don’t any option to save the reference.

also: Is a non water-suppressed spectra also acquired for csi, from the whole slab region? If so, is this used for referencing, or does the signal vary too much spatially?

Thank you,
Paul
