External Email - Use Caution Hello FreeSurfer Experts,
Now I have a custom annotation file (only the cortical surface). May I ask how could I use it to extract the mean time series from the fsfast-preprocessed fMRI data? I have tried to transform this annotation file into anatomical volume first: mri_aparc2aseg --s fsaverage --annot test --o test.mgz It seems I cannot do it to the left and right surface respectively, right? How should use this .mgz file next? Any suggestions would be appreciated. Best wishes, Zhi Li
