[Freesurfer] freeview of freesurfer 7.1 incompatible with merged overlays

External Email - Use Caution Hello Freesurfer experts, I recently upgraded to Freesurfer 7.1. Many nice changes so thanks for that. I often work with merged gifti files and the previous stable version of Freesurfer/Freeview (6.0) had no issue with them. Now, Freeview can view

Re: [Freesurfer] extracting clusters for each timepoints for longitudinal analyses

External Email - Use Caution Thanks Doug. I ran multiple comparisons to get the clusters. However, I want to extract the clusters values for the individual timepoints. The paired t-test does a paired-difference (timepoint1 - timepoint2) and I presume the significant clusters come

did you run the correction for multiple comparisons to get your clusters? If so, then there should be a table with a row for each subject and a column for each cluster. On 6/16/2020 11:03 AM, miracle ozzoude wrote: External Email - Use Caution Hello, I ran a pet longitudinal paired
