Re: The same Stev operator, different assignment forms, different simulation results in easyspin-6.0.0-dev.29

Thanks; I found that this Stev operator seems to have different descriptions in different versions. There are several versions that do not support some old assignment formats. For example, the new version does not seem to support aF items anymore. Should we use the format in the developer version? W...

Re: Five nucleus spin system

From the perspective of A, the first four magnetic core splittings can be completely ignored. (Even if you work hard to figure it out, the X-band will be completely buried by the splittings of Co) .It is a simple mononuclear Co compound. So I deleted the calculation parameter items other than -Co an...

Re: exporting data from esfit

I recommend baseline processing of the original data first. You can try MATLAB's ready-made detrend function.

esfit does not support parallel simulation

I turned on the MALTAB quad-core parallel computing command, but from the Windows task manager, MATLAB is indeed quad-core, but the easyspin esfit function still seems to run on a single core. I hope that in the subsequent updated version of easyspin, parallel simulation of functions with complex c...

Re: esfit errors occur when the abscissa of the raw data tested by Bruker's instrument is Gaussian

1.Thank you very much for your warm reply! Very good suggestion! The fitting result is perfect. Code: clear, clf, clc; close all; % Import Data [b,spc,par] = eprload('OH_4.DSC'); eprsave('OH4',b/10,spc); [b,spc,par] = eprload('OH4.DSC'); plot(b,spc); axis tight; % Exp Exp.mwFreq = 9.616532; Exp.Rang...

Re: esfit errors occur when the abscissa of the raw data tested by Bruker's instrument is Gaussian

[b,spc,par] = eprload('OH_4.DSC'); eprsave('OH4',b./10,spc); %save as mT [b,spc,par] = eprload('OH4.DSC'); % reload data plot(b,spc);% mT axis tight; but, This is too much toss. Can developers slightly change the esfit function? Automatically identify the horizontal axis of the data, and then automa...

esfit errors occur when the abscissa of the raw data tested by Bruker's instrument is Gaussian

The horizontal axis of my Brooke raw test data is Gauss. When I use esfit to simply simulate EPR parameters, error is reported directly. What is the corrective solution? Convert Gauss to mT? code: clear, clf, clc; close all; [b,spc,par] = eprload('OH_4.DTA'); plot(b,spc);% Gauss axis tight; Exp.mwFr...

Re: The optimization method does not support tcorr exchange systems

Thank you for your answer and look forward to adding this feature in the later update of easyspin!
good luck!
