Re: Relaxation curve fitting
Dear Edward and Troels, Thank you very much for your suggestions. Now the intensities.agr file can be opened and displayed by qtgrace on my computer. Regards, Mengjun Citat af Edward d'Auvergne : Hi, The qtgrace program seems a bit buggy. I have tested it on a Windows 7 VM, and see the same problem. Opening the file by clicking on the 'File->Open' menu results in a white screen. But double clicking on the file and opening it in qtgrace shows the file. You can make the graphs appear again in the blank screen as they are just hidden! - Click on the 'Edit->Explorer' menu item. - The 'Graph G0, type=XY' item is grey because it is hidden. Right click it. - In the popup menu click on 'Show'. You will now see the graphs. For this bug there is nothing I can do as it is in qtgrace and not relax. I am now trying to replicate the relax grace.view user function failure. Regards, Edward On 4 March 2014 20:59, wrote: Hi Edward, Thank you for your suggestions.

You should always keep your data files separate from the software files. Mixing the files together is quite dangerous and might result in program files or directories being overwritten by data and results files.

Re: Relaxation curve fitting
Hi Mengjun, the rx.out file contains the fit parameters of all the spins. The results and save files can be loaded into relax again to manipulate the stuff further and e.g. write the values again into another file. To display the intensity you either use the provided grace files, or you do it like me and read the out files and your original intensitiy files with your "other" program for plotting. I do this in R, mainly because I used R for fitting before I learned about the existence of relax. For this to work, you'll also have to write out the initial intensity I(0), e.g. by typing: > value.write(param='i0', file='i0.out', force=True) If you want, and know how to write R, I can provide you with my scripts.

Re: Relaxation curve fitting
Dear Mengjun. Let me extend the previous explanation. Use the GUI to load results.bz2 file. Then use the User function: Value write, to write a text file with the desired results. These are just flat text files as: rx.out and can include intensities instead, of normalized intensities. Use these files to plot in any program. Or use the User function: Grace write, to make grace files.

Relaxation curve fitting
Hi Edward, I have tried to use relax_fit.py to extract R1 data, I have got 3 files: rx.out file (R1 values), rx.save.bz2 file, and results.bz2 file, as Xmgrace is not available on my computer, I want to display the intensity decay curves in others software, so how to extract the raw data from the output (results.bz2) of relax_fit.py? It seems rx.save.bz2 file is same to results.bz2 file. Thank you very much.

Re: relaxation curve fitting
Hi Romel,
The problem is that unfortunately the 'inv' model is simply not
implemented yet. This is the model for the very old-school inversion
recovery type R1 experiments whereby the magnetisation returns to the
Boltzmann equilibrium. I'm guessing you should be using the 'exp'
model instead. This is the standard 2 parameter exponential fit
whereby the magnetisation goes to zero. This is the standard nowadays
as it is considered far more accurate for the extraction of the rates
(simply by having one less parameter to fit).
If you have collected the old-school data, there is a relax branch
created by Sébastien Morin for handling this experiment type. This is
the 'inversion-recovery' branch located at
http://svn.gna.org/viewcvs/relax/branches/inversion-recovery/.
However this branch is not complete and will require someone willing
to dive into C code to complete it (see
http://www.mail-archive.com/relax-devel@gna.org/msg03353.html). Note
that if someone does know C, completing this will require about 50
lines of code changed in the maths_fns/relax_fit.c and
maths_fns/exponential.c files (my rough guess anyway). It should be
incredibly trivial for someone with C knowledge. Anyway, I hope some
of this info helps.
Regards,
Edward
