Hello,
Currently, I'm collecting more NMR data so I haven't had much time to analyze
the data.
Usually, I extract the raw peak heights at each CPMG Hz for each residue
(assignments saved in my ccpnmr project) so I don't have a peaklist for my
CPMG data. The same is done for my fast time scale dynamics (T1/T2/NOE).
So I was wondering if there was a way to set up the files in a tabular format
by hand? (an example of such a table would be very helpful). I was hoping if
there was some way to fit my dispersion data just on a per residue basis,
similar to how another NMR program, NESSY, takes in data.
Thank you for your time and patience, as an undergrad a lot of the
information and navigation is quite overwhelming so its great to have some
help!
Regards,
Sam

Hi Sam,
I was wondering if you still had problems with the loading of peak
heights for relaxation dispersion in relax? It should be pretty
flexible and handle most formats you throw at relax. If you have a
peak list format that is not supported, it would be appreciated if you
could create a support request (https://gna.org/support/?group=relax,
https://gna.org/support/?func=additem&group=relax). If you attach a
truncated peak list to the request, slightly randomised if you would
like to keep the data private, then that file could be used to quickly
implement support for the format.
Cheers,
Edward

Hi Sam.
Try to have a look on the wiki:

Maybe you can figure out something.
If you need more help.
Make a suppert request
https://gna.org/support/?group=relax
Upload an example peak list for each CPMG frq.
Make a file, listing filename for peaklist and corresponding CPMG frq.
You need to determine the error of your experiments.
If you have peak heights which are replicate/triplicate, then this is fine.
Or else you need to measure RMSD of the noise in the spectrum.
What is also:
Relaxation dispersion CPMG constant time delay T (in s).
The NMR field strength of the spectrum. (750 MHz ?)
Best

Hello all,
I am an undergrad that is new to the field of NMR and I was hoping to get
some basic help in setting up my data for analysis.
For my CPMG relaxation dispersion experiments, I usually process my data
through NMR pipe and then extract the peak heights through ccpnmr with each
plane as the CPMG frequency. In the end for each residue, I get the peak
height at various CPMG frequencies.
However, I'm not sure how to format my table or know what software I can
use to format my data so that I can input it into relax. If anyone has any
help, I'd greatly appreciate it since I'm very new to the field and all the
analysis that comes with it.
Regards,
Sam
