sorry for being dense - but what then would be the best way to acheive better wm intensity? We get much better contrasts and better segmentation in fronto-temporal regions when we run mri_nu_correct.mni. But then we still need to fix topological errors. My understanding is that '-make all' fixes

Hi Ilana that won't work. I guess you could try copying nu2.mgz to nu.mgz and trying -make all (assuming you have a new enough version of recon-all) cheers Bruce On Tue, 4 May 2010, Ilana Hairston wrote: > Also re-sending my query - perhaps someone has experience with contrast > adjustments >

Hi there, We have been doing contrast correction using mri_nu_correct.mni (e.g., mri_nu_correct.mni --i FS090620ll/mri/orig/001.mgz --o FS090620ll/mri/orig/nu2.mgz --n 2). My question is, after subsequent corrections (control points, white matter) do we need to specify nu2.mgz as the target file fo
