Thanks for any help to this question(s)!

I am having a bit of trouble translating a cartesian interaction matrix into a spherical tensor, I have managed to do this by hand following the guide handed out by Ilya and using the tables of coefficients, but doing it in SpinDynamica leaves me a little bit lost. Are there any functions particularly suited to this operation, I didn't find anything in the usage examples but I might have missed them?

Cheers,

Johannes
