EasySpin forum

Hi all,

I have recently had to update my easyspin to version 6.
However, since then I have not been able to run any simulation. I changed the syntax according to the new esfit one and the esfit least square fitting window opens up.
Whenever I press "start fitting" everything seems to freeze and nothing happens. I am having the same issue on two different machines (mac and windows) and I cannot even run old files that I could simulate with older easyspin.
Is it a bug or am I doing something wrong?

Thank you

Luciano

I suggest trying to run of the fitting examples from examples/fitting and see if those work.
