Hi,
you are right! The Talairach ccordinates change. Unfortunately, the centroid coordinate of my data are outside the cluster. Do you have any suggestions about that?
Is this group data? Or otherwise on fsaverage? Or on the subject's surface? How are you determining that the centroid is outside of the cluster? It should give you a vertex number for the centroid (I think). I opted not to use the centroid by default for this reason. This can happen because the centroid is irregular.
I also tried your version of the script. The following message appeared:
mri_surfcluster: error while loading shared libraries: libnetcdf.so.6: cannot open shared object file: No such file or directory
I gave you a version for CentOS. Zeke, what do we do for the ubuntu distribution?
Since I use Ubuntu it is not so simple to switch from my current version libnetcdf.so.7 back to libnetcdf.so.6. Do you know a workaround?
Respectfully yours pfannmoe

I'm not sure, when I run it it results in different xyz. What version are you using?
I've put a copy of my version (for linux) here ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mri_surfcluster

Hi,
I am trying to compute centroid coordinates of maps for functional activation obtained from fsfast with mri_surfcluster. The command is:
mri_surfcluster --in /.../sig.nii.gz --thmin 3 --thmax infinity--sign pos --subject subjid --hemi rh --surf white --annot aparc --frame 0 --minarea 0 --sum ./tabular_surfcluster.txt -- centroid
Unfortunately, the centroid option has no effect. Results in tabular_surfcluster.txt with and without centroid option are identical. What am I doing wrong?
Respectfully yours
