how are you converting them?

Hi,
We are recently trying to get cortical thickness from freesurfer and
converting them to 32k. A problem we notice is that after converting
to 32k, all the cortical thickness values become negative. However,
when we load freesurfer thickness files in freeview, everything
appears normal. We wonder if merely inverting what we currently have
in 32k would be a good idea. Alternatively, we also calculated the
Euclidean distance of pial and white after they have been converted
into 32k space, which should be cortical thickness. However, when
comparing the inverted values and the "pial-white"values, we find that
there are some differences. In this case, has anyone ever had similar
issues and have suggestions on which one to trust?
Thanks!
Ariana
