For some reason, when I run that command, I get the following output:

Input volume  is : seg_mov
Output volume is : seg_mov_2

There are no errors, but when I check "mri_info" of the output file, the TR, TE, etc. values are still non-zero. Any ideas what could cause that to happen?

Thanks!

yes, I think so

thank you. Would the command simply be something like this: mri_modify -tr 0 -te 0 -ti 0 -fa 0 <input.mgz> <output.mgz> ?

      Hi Mark

      the formatting got messed up so I can't parse your table. You can get around this using mri_modify, and just setting
      everything to 0. As for the effects, look at the images and see what you think.

            Hello freesurfers,
                I currently have a series of images with various TR,TE,TI,FA values. I
            would like to use mri_ca_train to create a .gca atlas based on these
            segmented volumes. Unfortunately, they all have slightly different control
            parameters (TR,TE,TI,FA). Is there any way around this problem, or would it
            be best to break the subjects into multiple groups with the same control
            parameters?

            Here are the various parameters: [each row is a subject]

            TR
            TE
            TI
