what different brain images do you mean? You can view them with the surfaces via: tkmedit norm.mgz lh.white -segmentation aparc+aseg.mgz or tkmedit norm.mgz lh.white -segmentation aparc2009s+aseg.mgz the tools will be part of FS 5.2 when it comes out in the next month or so. If you really

Hi Spanier definitely don't invoke recon-all with the FLAIR image. We have some tools in 5.2 for this, but you would call it as a postprocessing step with a different command line in any case. Instead, you can use bbregister to register the flair to the surfaces and resample it. cheers Bruce
