Hey experts,
Thank you very much for your advice!
So I guess my best guess would be to use recon-all with -nuintensitycor-3T and add an expert option file for "-b 20" and "-n 5". These flags belong to the "mri_normalize" binary?
Best regards Thomas

Hi Michael
that's a good thought. Let me talk to Nick, and see if we should default to it and have a 1.5T flag instead

Yes, that flag still works in 5.1.
Bruce, think these parameters could be default in 5.2? It's a long extra flag (that is, I imagine, someone arcane knowledge) for what has to be the overwhelmingly modal field strength these days.
Sorry to hijack, but this would be nice!
Cheers, Michael

I recently noticed that they help us with a very similar problem...
Also, I recall that for FS v5.0 there was a flag -nuintensitycor-3T for "optimal parameters for nu_correct for 3T scans" (as described in release notes for v5.0.)
Bruce, the -nuintensitycor-3T is still available in v5.1 right? If yes, then we could combine the options the two set of options and run recon-all with "-b 20 -n 5 and -nuintensitycor-3T" for the 3T scans? Would this be reasonable or does this combination not recommended ?
Thanks Mehul

As you can see from the picture, the autorecon does not work properly (for WM/Pial surfs) with my files: Especially in the temporal lobes. I am working with the SPGR files of a 3T GE Machine. Is there any way to optimize the autorecon results for SPGRs? (Except the lavish application of CPs.) Best regards Thomas
