Hi James,
you can also supply the value of nc_proc when you run xfb, like in:
xfbnc_proc 2
This example scales down the data twice. However, you can only scale the data
more down**
(or less up) than the command would have done without the argument *nc_proc*
So find the largest nc_proc in your series and apply them to all planes.
Goodluck,
Eiso

Dear James,
I think that is NC_proc parameter related scaling problem processed in TopSpin.
When you process your data in TopSpin, intensities will be relatively adjusted
based on NC_proc parameter.
1. You can open procs file with a text editor like wordpad, find ##$NC_proc=
and edit them to have all same values (e.g. -8). Then, run easy_bruk2ucsf.
2. Another way is just to run bruk2ucsf with NC_proc parameter on
terminal. Syntax: bruk2ucsf bruker-file ucsf-file opt: NC_proc
Best,
Woonghee

Starting from Topspin, I had a pseudo 3D experiment. I repeatedly used
xfb to get all my 2D planes. Then, when I use the bruk2ucsf utility from
the NMRFAM pulldown menu in nmrfam_sparky, I see command lines such as:
/[DataLocation]/102/2rr/101.uscsf|-8
/[DataLocation]/102/2rr/102.uscsf|-9
/[DataLocation]/102/2rr/103.uscsf|-8
etc. But sometimes, I have 34 slices and about 30 of them have the -8, and
then only 4 have the -9, and then -9 2D files are significantly higher in
intensity across the board for peaks I know should be the same height in
all of them. What does this final number mean and is there any way to
change it?
Thanks,
James
