T1 pseudo3D data
- Dear colleagues,
I collected a T1 pseudo3D experiment containing 10 delays specified in the vd list.
The data was collected using the loop set-up below.
goscnp ph31 cpd3:f3
3m st ivd
lo to 3 times nbl # number of delays in the vd list
3m ipp3 ipp4 ipp5 ipp8 ipp9 ipp31
lo to 4 times ns # number of scans
d1 mc #0 to 4
F2EA(igrad EA & ip5*2 & rpp3 rpp4 rpp5 rpp8 rpp9 rpp31, id10 & ip6*2 & ip8*2 & ip31*2)
To process the data I used the conversion macro below, in addition two alternative processing approaches that used either the COADD and QMIX functions. The problem I am experiencing manifests as large first order phase corrections and ultimately not properly phased planes. I believe that the planes are not been properly divided, since I have duplicate planes that have completely different intensities.
