Thank you again Doug, I've tryed all the possibilities you said, but still not have a nii image, It says that it's reshaping to 6, but also when I change to another factor number it always says reshaping to 6, and the resultant nii image has still 163842 vertex so no program is able to read it, I'm working with FS version 5.0.
