How did you compute the average? If using mri_glmfit, it will store an rstd.mgh file with the stddev, you can load it like any other overlay.

Hello,

After computing the average thickness of an average subject (prior to Qdec), how can I estimate and get a map of standard deviations of the thickness measures across the subjects I've averaged.

Thanks,

Ines
