Ok. So the first is the input and the second is the output, correct? So I'll have a different file for each out put? Is it possible to have a table with the different measures after the threshold?
Thank you very much and I apologize for the naive questions...

What you call the output label is up to you. What you call the input label is more important - it has to be a file that actually exists.

Ah ok! Sorry... In both places?

It's .thresh.label, not .threshold.label.

Hi Anastasia! The command in the recon-all.log is this one: mri_label2label --srcsubject fsaverage --srclabel >

And I tried substituing BAxxx.label by BAxxx.thresh.label like this: mri_label2label --srcsubject fsaverage --srclabel
/home/user/visao/Freesurfer/fsaverage/label/lh.BA1.threshold.label > --trgsubject SUSANAFERREIRA --trglabel ./lh.BA1.thresolh.label --hemi lh --regmethod surface
gave an error : SUBJECTS_DIR /home/user/visao/Freesurfer/

Thus, I substitued only in the second BAxxx.label and it
worked. I > thought that was it, but then the values were the same. I'm sorry, I'm not sure what is missing.
Thank you! Andreia

Hi Andreia - What you're rerunning is using BAxxx.label instead of
BAxxx.thresh.label. So of course the results will be the same as before you copied over the BAxxx.thresh.label files, b/c these new
