Hello. I am a student and I am using this program to count alpha radiation tracks on LR-115 detectors. I’ve encountered a few problems. First, my image is RGB and I need to make it Grayscale. The function does not work and it shows an error that says this picture is already Greyscale. But it is not. Since my .tiff file is bigger than the limit I’ll attach a Google drive link. I didn’t find any image sharing websites to suport .tif files. https://drive.google.com/open?id=0B1RgcKjWCEvSeFFaY083VFlTYms
The second problem that I’ve encountered is that I can not substract background so that it will be like this: https://drive.google.com/open?id=0B1RgcKjWCEvSYVlOYXRhTUFKbG8 . Also a google drive link.
Note: the second file is processed file of the first file using ImageJ.
Thank you in advance!
