simulation abort error when using "PostConvNucs" with chili

Hello everyone, when I try to simulate the spectrum of a two-electron spin system with S=1/2 with chili using the PostConvNucs option with the following code: clearvars Exp = struct('mwFreq',34.01078,... 'Range',[1204.4 1219.4],... 'nPoints',3000,... 'Harmonic',1,... 'ModAmp',0.05,... 'mwPhase',5*pi...

Re: globally fitting multiple spectra with esfit

Thanks with the code esfit('globalfit',[spec_X(:,2);spec_Q(:,2)]',Sys1,Vary1,Exp,SimOpt,FitOpt); esfit runs and open the GUI. But now I get the following error message when trying to start a fit in the GUI: Reference to non-existent field 'scale'. Error in globalfit (line 13) scale = Sys.scale; % cu...

globally fitting multiple spectra with esfit

Hello, when I try to start a fit using the example "globally fitting multiple spectra" in the Easyspin documentation with the following command esfit('globalfit',{spec_X(:,2),spec_Q(:,2)},Sys1,Vary1,Exp,SimOpt,FitOpt); , (where spec_x and spec_Q are matrices containing the B-values in the ...

same parameters - different simulation curves

If I run a typical simulation code with chilli in the new Easyspin version 5.2.5 I get a different simulation curve as with the slightly older version 5.1.12, despite the fact that the simulation parameters remain unchanged. As can be seen in the attached picture “simulation curves”, the signal inte...

Re: Problem simulation function chili with new EasySpin 5.2.

I use a machine with Windows 10 Pro (64 Bit) and Matlab R2016a. If I run the code with Opt.Verbosity = 2 I get the following output: >> Simulation single spin system component 1: 1 isotopologues -- slow motion regime simulation ---------------------------------- field sweep, mw frequency 9.429649 GH...

Problem simulation function chili with new EasySpin 5.2.4

Since I use the new Easyspin version 5.2.4, the error code: "Error using magint g tensor must be symmetric for this method." is always obtained when the following simulation code is executed: Exp = struct('mwFreq',9.429649,... 'CenterSweep',[336.05 9.9794],... 'nPoints',4096,... 'Harmonic'...
