I only have one input. The last posting's orig.jpg was 001.mgz, and motioncor.jpg is orig.mgz. We usually run motioncor because it produces the orig.mgz which has been conformed. On Mon, Jun 3, 2013 at 2:41 PM, Bruce Fischl wrote: > what does the 001.mgz look like? Do you have more than one inpu

what does the 001.mgz look like? Do you have more than one input (otherwise you wouldn't need motion correction)? If so, you'll need to do this for each one On Mon, 3 Jun 2013, Erin Browning wrote: The orig.mgz is hyerintense (there's a screenshot of it in another post now). The AFNI file is i

try what I suggested and see if that helps On Mon, 3 Jun 2013, Erin Browning wrote: Here is an example of what AR2 looks like (without playing with niterations or anything like that to reduce the overall hypterintensity). The white matter line is much closer to the pial line than it should be.

Hi Erin that can happen if you lose too much dynamic range when "conforming". What does the orig.mgz look like? What voxel format is the afni file in (uchar? float?) mri_convert has a -ns 1 flag to turn off intensity scaling ("no scale"). If the brik was in float you could use something like (
