Dear Bruce and FS experts
 
I'm sending attached 2 images, 1) one with the original subject, without any transformation (just from NIfTY format to mgz format), and 2) the T1.mgz created during the recon-all step, note that the original image has the background with a higher intensity, could be the background the problem to the recon-all? is there any way to put the background to zero? 

 
Best
Gabriel

I guess the intensity from my original image is not good, how can i fix it to make the recon-all?
