In freeview, you can use :overlay_color=colorscale,settings maybe Ruopeng can weigh in on exactly what to set them to to get the colorwheel Are you also looking to have freeview snap pictures for you? On 7/18/19 11:57 AM, Matthieu VANHOUTTE wrote: > External Email - Use Caution > Sorry not to be

When you run mri_surfcluster, save an output cluster number (--ocn) output, then feed that into mri_segstats. On 7/18/19 11:44 AM, Mark Wagshul wrote: > > External Email - Use Caution > > Hi.  I have a question about cluster size determination within Freesurfer. > > We are running linear

Hi Cristian it's not so much the difference in voxel size as it is the thickness and anisotropy of your FLAIR voxels. You would be much better off getting 1mm iso which would have comparable SNR to what you have now. You can try it, but the 3.5mm slice thickness will probably mess stuff up
