Dear Freesurfer community,

Just a simple question : is there a command-line that allows averaging voxel values from different time frames, transforming dynamic 4D volume into a static 3D volume ? mri_convert allows to skip some early frames (--nskip) or drop some at the end (--ndrop), but I don't see any option for averaging.

Thanks for your help,

Best,
