Re: [Freesurfer] Which T1 volume to use for coregistration with PET volume

2018-12-28 Thread Michael Sughrue 
External Email - Use Caution

Has anyone had success extracting surfaces of brains with obviously
abnormal surfacespost-surgical or very distorted cortices from tumor
etceven if the extraction is imperfect, is it possible to do with
freesurfer and get something imperfect but useable. typically this gets
hung up at the fix tesselation step.

if this isnt possible presently, any suggestions about how to create modify
the source code to create such a tool?

[Freesurfer] Which T1 volume to use for coregistration with PET volume

2018-12-28 Thread Matthieu Vanhoutte 
External Email - Use Caution

Dear Freesurfer’s experts,

I used mri_coreg command to coregister PET image onto T1 volume. Basically, 
this command coregister PET image onto orig.mgz volume (default target). 
However, I wonder if T1.mgz wouldn’t be a better target since it has been 
corrected for inhomogeneities and intensity normalized ?

Thanks for helping !

Best,
Matt
