= Name =
mri_xvolavg - averages multiple volumes (including 4D volumes)

= Synopsis =
mri_xvolavg --vol <invol1> --vol <invol2> [-vol <invol3> ...] --out <outvol>

= Arguments =
== Required Flagged Arguments ==
|| --vol <invol1> --vol <invol2> [-vol <invol3> ...] || input volumes ||

== Optional Flagged Arguments ==
|| --vol_type  || input volume format ||
|| --out_type  || output volume format ||

= Outputs =
|| <outvol> || output volume ||

= Description =
[[mri_xvolavg]] averages multiple volumes together (including 4D volumes). mri_xvolavg accepts all input types as mri_convert (see mri_convert --help  for more information). There is another program called mri_average which has similar functionality.
[[mri_average]] can align the input volumes and force them to conform to the COR format. However, it cannot process volumes with multiple frames.

= Examples =
== Example 1 ==
mri_xvolavg --vol f --vol g --outvol out
