[Freesurfer] bbregister and FLAIR

2014-05-23 Thread Kayle Sawyer
Hello,We have been examining the pial surface adjustment with FLAIR scans, and the improvement is quite dramatic. There are MANY areas where the pial surface was clearly wrong and has been substantially improved, considerably reducing (often eliminating) the need for manual pial corrections. I sugg

[Freesurfer] finding cluster peak vertices

2014-05-23 Thread Milde, Christopher
Dear Freesurfers, Is there a way to smooth already preprocessed functional images* (FEAT, FSL), which I coregistered to the reconstructed surfaces (reg feat2anat), on the cortical surface? Furthermore, I would be interested in finding the cluster peak vertex after smoothing the EPI on the reco

Hi Maia it's hard to say since I don't really know what steps worked in 5.3 or why vs. 5.1. I guess you could try starting from after the normalization in 5.1 and seeing if they go through the rest of recon-all Bruce On Tue, 20 May 2014, Maia Pujara wrote: Thanks for your response, Bruce.
