Inversion recovery in v3.5

Hi,
I was checking the 3.5 pre-release and was really curious about the the new dynamics module. First of all, thanks a lot for all your efforts you put into all the projects.

I tested T1, T2, and T1rho and all works well, but I ran into issues with inversion recovery experiments. Somehow there is never a fit. I found the fields in the fitting tab where you might give some initial guess for the fitted values, but I didn’t manage to unlock/edit them.

I know it’s a pre-release but I was curious. Or does the IR require some sort of normalisation beforehand?

Thanks!
Alex
