The second step is to convert the Bruker-/Varian-style data into NMRPipe
format. On the second page of the MDD wizard edit a FID_SP.COM
script for BRUK2PIPE/VAR2PIPE conversion just as you would
do for a regular spectrum. Most parameters should be read correctly
already, but double check the acquisition mode for the indirect dimensions
as these are often difficult to get right in an NUS experiment. Make
sure that
- Input file is ./SER.SP or ./FID.SP
(or the name you gave in Step 1).
- Double check the number of points in the indirect dimensions. You
should use the values for complete spectrum. E.g., if you are recoding
30% of 300 x 50 data points, you should still use 300 and 50 for
the corresponding dimensions in -yT and -zT fields. Change the -yN
and -zN fields to corresponding number of real points (in this case
600 and 100).
- Double check the acquision modes. The automatic parameter readout
sometimes places Echo-AntiEcho detection mode into a wrong dimension.
Apparently, with a newer version of TOPSPIN (2.0) there might
be some trouble with the DECIM filter when converting. You
might need to install the most recent version of NMRPIPE program.
Save the conversion script and perform the conversion by pressing
the corresponding buttons. Then move to the next step.
