Process all file in a folder by function

Hi, i write a function which process a image file : main(filename) where "filename" indicates the image to be process. I would like to process all the images in the folder "tot16", i would use this function <http://www.mathworks.com/matlabcentral/fileexchange/25316-auto-process-all-files-in-sub-folders&watching=25316> but not working. I write the function call :

PathRunner('/Users/XXXX/Documents/MATLAB/Thesis' , '/tot16' ,@main , flag , '*.raw' )

where :

• /Users/XXXX/Documents/MATLAB/Thesis is the directory where is the function @main
• /tot16 is the directory which contain all image files

Please explain, what "not working" exactly means.

The file type parameter must be given to the function as a cell array of strings, even when you are only passing in a single file type string.

{'*.raw'}
