Valentina,

confirm that all three images are the same voxel size (height,width,depth).

you can do this using mri_info, for example:

mri_info 001.mgz

will output:

Volume information for 001.mgz type: MGH dimensions: 256 x 256 x 128 voxel sizes: 1.0000, 1.0000, 1.3300 ...

and for my 002.mgz, the voxel sizes are the same (and the 003.mgz would also need to be the same). unfortunately, freesurfer does not tell you if your three input volumes differ in size (at least not in the current stable3).

Hi, I'm trying to run -autorcon1 of a subject who has 3 mgz images but always came out an error about the motion correction. So I tried run the step using just 1 image and it has gone fine! Have you any suggestion about the reason? The images look good!

Thanks Valentina

Hi Valentina,

We're going to need some more information in order to be able to help figure out the problem. Please refer to the following webpage to see the things we need to know.

Hi Valentina,

Have you tried the following command?

recon-all -motioncor -s <subjectid>
