I feel silly, but I have to ask for help. I try to Import>Image Sequence, and all the file names in the folder are grayed out, even the .tifs. What could be the matter? Can I resave these images (using Mac Preview, for instance) in a different format to make them ImageJ-friendly? Help me please someone!
You need to choose the folder, not the contained image files!
All images in the chosen folder will open as an image stack.
Wow that was fast. Duh. Thanks!
