Descr iption: This scr ipt allows the user to load 3-D TIFF images, such as those derived from confocal or 2-photon microscopy, into the MATLAB workspace for analysis of colocalization between two images in 3-D. It includes a function <getstacks> that is used for loading the images using the Windows file browser via <uigetfile>. -Descr iption: This scr ipt allows the user to load 3-D TIFF images, such as those derived from confocal or 2-photon microscopy, into the MATLAB workspace for analysis of colocalization between two images in 3-D.
