Hello Nick. Bruce said you can give me the latest Freesurfer version. Actually, as I already mentioned, I have a problem with negative cortical thickness and it bothered me very much.. but it's fixed in the most recent version of mris_make_surfaces and mris_thickness. Freesurfer wiki homepage doesn't contain fixed version.. I know you are very busy, but May I receive a fixed version from you as soon as possible?

Thank you.

Sincerely, EK

Hi Bruce. Thank you for your reply. But I still wonder because I used the most recent version ' freesurfer-Linux-centos4-stable-pub-v4.5.0'. Did you mean future released version 5.0 ? Please let me know right place that obtain the 'mris_make_surfaces' and 'mris_thickness' files. The released note page does not contain this files at now...

Sincerely, EK.

Hi EK,

this was a bug I fixed a little while ago. The negative thicknesses should all be in non-cortical regions, but it's fixed in the most recent version of mris_make_surfaces and mris_thickness. The negative value should all be 0

cheers, Bruce

Dear all I performed recon-all -s subjectID -qcache and obtained thickness data which was normalized to fsaverage template. I'd like to extract thickness value of the '-rh(or lh).thickness.fwhm0.fsaverage.mgh' file in each subjects, so it was transformed to the ascii file format. However, the thickness data obtained from the ascii file did have some negative values. !!! Interestingly, the thickness value that was not normalized to the fsaverage did not have negative values so I was very confused.. Please let me know how can I treat the negative value.

I really THANK YOU for your reply.
