Show a brain's slice. "rest_sliceviewer" can be opened more than one instance like MRIcro, and supports multi-slice, overlay and so on. by Xiao-Wei Song
Usage: hFig =rest_sliceviewer('ShowImage', AFilename, CallBack);
rest_sliceviewer('Delete', AFigHandle);
Detailed usage is the code file "rest_sliceviewer.m"

I indeed did not find the 'imresize_old' and 'imresize' files. Could you please find a solution? Thank you!
