Dear Doug, I'm very thankful for your helpful comments! I will check the feat2surf script and apply it to map FSL-data in individual and common space (preconditions: existing FEATdir with non-smoothed EPI's and applied reg-feat2anat). I will make use of the -projfrac 0.5 to sample in the middle of the cortical ribbon (to account for drain vessel effects).
According to the intended distance measures, relative measures between peak voxels are also fine. So, maybe mris_pmake is still a good option... Greets, Chris Christopher Milde, M.Sc. Biol.

I'm guessing it will *work* on the sphere in that it will return a path, but the distances between vertices have no relationship to anatomy. It might fail on a flat map because it is a patch. doug On 03/20/2014 10:43 AM, Milde, Christopher wrote: > > Dear Surfers, > > At moment I'm dealing with a huge dataset, preprocessed (with and > without smoothing) and statistically analyzed in FSL FEAT. > > I used the reg-feat2anat to project functional EPI on inflated MPRAGE > (recon-all). > > Because *I'm interested in measuring Euclidian distances between peak > voxels*, I want to project *FEAT EPI-data on cortical flat maps > (mris_flatten) or spherical surfaces*. > > èIs it possible to project FEAT-data on flat_maps? > > èDoes mris_pmake* works equally fine on different projections of the > EPI to ANATOMY (sphere, flat map) to measure peak/vertex distances? > > *https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2011-April/017 > 866.html > <https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2011-April/0178 > 66.html> > > I'm a quite Surfer-newby.
