Hello Evan
Very very thanks for your time and response. Actually, I did what you told and with other images, I have results I think the problem is for my dataset and maybe need an extra setting in SPM. I have this error:
Failed 'Segment'
Error using sqrtm (line 35)
Expected input to be finite.

The following modules did not run:
Failed: Segment

I attach my dataset and if you have time it is really of your kind to guide me. 
Again thanks and wish you best
