when you overlay the ?h.curv file on the inflated surface does it look
correct? Are there both red and green regions?

Yup. That looks fine.

and if you click on the gyri do you get negative values?

p.s. sorry, the mean and Gaussian curvatures displayed in
mris_anatomical_stats are absolute value. I forgot this, sorry. The
integrate Gaussian curvature is actually a topological invariant, so
doesn't tell you much about the surface. Do you really need signed mean
curvaature averaged over a r

Not that I know of.

Dear fellow FreeSurfers,
does anybody know how to account for interleaved slice acquisition of
functionals in fs-fast? Basically all my scans were taken interleaved

No, I don't need signed values necessarily.
So just to double-check then, higher mean curvature for averaged across a gyral
ROI label would mean the gyrus has a more steeply peaked appearance, whereas
high values for a sulcal label would, conversely, mean the sulcus resembles a

pretty much, although if you have saddle points the mean curvature can
disappear (since one direction has positive and the other negative
curvature)

Try using stc-sess (it is a front-end for fsl's slicetimer).
