I developed this macro as a modification of the "arrange channels + stack to tiff" macro for a labmate of mine. It is fairly specific to her project, but a good backbone for further modification if need be. She needed to be able to take a stack of four channel, six slice z-stacked images and compress them halfway before performing dendrite selection and removing one of the channels. I set it up so she could do that and also retain the initial function of the macro. It might need some more troubleshooting, but it is definitely functional!
