can you send us the full command line and screen output of what you ran?On Mon, 5 Aug 2013, Mark Plantz wrote:
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.
cheers

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
flip angle
