Hi - I'm not sure which FLAME option you are running, but if you are running the full FLAME then: no, that equation is not used; the DOF will be estimated empirically from the shape of the posterior density function of the fitted parameters.

Cheers.

In looking through the source code for flameo, it looks like degrees of freedom is calculated using:

tdofs[t](px,py,pz) = ntpts - nevs;

So, in the model I sent earlier, ntpts=32 and nevs=11, which I think explains the degrees of freedom problem.
