Hi Rachel,

It appears that your nifti has RGB datatype (128). Freesurfer doesn't support that yet.

Best,

Hi Rachel

Is RGB the correct type for the file? What kind of data do you expect it to be?

Cheers Bruce

External Email - Use Caution I see, thank you!

Do you know of a way I can convert it to a file type that is supported? Or what an alternative file type might be?

Thank you again! Rachel
