Hi Sandro yes, you will find some dependence. Much as we would like it to be otherwise when you change resolution you change a bunch of other things typically (min TE, bandwidth, big SNR changes) that will cause changes in our measured volumes cheers Bruce On Sat, 11 Jul 2015, Sandro Marin

Hi Bruce, Thanks for your help. Yes, I would like to run recon-all on each one separately and then use all the output data irrespective of the original MRI voxel size. In other words, do the output values (i.e white matter volume) depend on the voxel size of the original MRI? Best, Sandro Message

Hi Sandro can you clarify what you mean? Do you want to run recon-all on each one separately? That would be fine. Or do you mean somehow average all the different res volumes into a single recon? cheers Bruce On Sat, 11 Jul 2015, Sandro Marini wrote: Dear FreeSurfer experts, we have col

Dear FreeSurfer experts, we have collected some data with different voxel size (from 0.78 to 0.94 mm iso). I would like to do an analysis of all these scans. Is it possible ? Should I use -cw256 option to make the sample uniform? Many thanks Best, Sandro __
