average

Purpose

This utility allows you to compute the mean and standard deviation of several images or several volumes. The result is stored in two files called[fn_root].med.xmp,[fn_root].sig.xmp (in the case of images) and[fn_root].med.vol,[fn_root].sig.vol (in the case of volumes). Notice that [fn_root] is the first part of the input sel filename

Usage

$ average -i [selfile in] ...

Parameters

• `` Compute the mean and standard deviation of a bunch of files, they can be either volumes or images
• `` The default is to apply the transformation stored in the header of 2D images. Use tjis to switch it off

Examples and Notes

Compute the mean and standard deviation of a selfile

$ average -i g0ta.sel

The result is stored ing0ta.med.xmp andg0ta.sig.xmp.
