Dear Antonio,

“-norm3diters“ are the iterations of mri_normalize, whereas “-nuiterations” refers to the number of cycles of mri_nu_correct.mni. I suppose they both work in v6. If not you can simply create a file with expert options.

Hope this helps!

Best, Falk

Hi,

I have a question regarding -nuiterations and -norm3diters. I would like to get a feel for the options available for fine-tuning the intensity normalization in FreeSurfer 6.0.

I've seen mention of -nuiterations on some posts. Is this still an option in FreeSurfer 6.0?

The reason I ask is because under the "Expert Preferences" section of recon-all -help there's only mention of "-norm3diters". However, further down, under the second "Expert Preferences" section, there's a description of -nuiterations as well as -norm3diters.

Thanks!
