You can use mri_segstats on the surface. You can either use the --label option or, if you have a lot of labels, you can merge them into an annotation with mris_label2annot and then use the --annot option to extract from all at once (values are extracted from each region separately; this just might save some time/typing).

Hi,

Last year, I have been working for four months with David Salat and so, I have learnt a lot, including the dt_recon command.

From David, I also learnt to use mri_segstats command in order to get minimum p-values for each label in my volume.

However, now I have performed cortical thickness analyses. Based on the results on the inflated surface, I created labels and deprojected them to native space, to get the statistics.

Now, I also would like to have the minimum p-value of each label in the cortical thickness analyses. However, the mri_segstats command is not suitable for surfaces.

Do you have any idea how I can extract these minimim p-values?

Thank you very much.

Best

Heidi.
