We have been trying to use the MRI wound healing macro to analyze scratch assay images. We have tried to follow the instructions on the help section of the macro. When we run the macro the tool bar displays the macro commands and the image flashes like it is processing. At the end an empty ROI manager opens but no results table and no overlay with the "found edges" outlines. Could someone please help us figure out what is going wrong? I tried to attach a tiff to this message but it was too big.
