how to find mean image of 100 (.tif) in a various subfolders

Hi All,

This is the path:

path = 'F:\Toshiba\Results\100 Tests\6%\120D, 1B\';

There are 100 subfolders inside 120D 1B that are labelled: '120D, 1B001','120D, 1B002'. Until...'120D, 1B100'.

Inside each folder, for example inside '120D, 1B001' there are .tif images. I only want to get the mean image of: '0001000007.tif' the next image is called: '0002000007'.(in folder:'120D, 1B002')

How can I do this?

Please help! Thanks in advance. :)
