Hi everyone.. is it possible to analyse our data saved as JPEG in ImageJ? I did tumourspheres culture under hypoxic condition and have to take the pictures of my spheres in multiple 6 well plates, which usually took quite a lot of time and I try as much as possible to minimise the time the plates are outside due to the hypoxic condition. So usually I saved my picture in JPEG without the TIF format. I knew that usually analyses are usually done on TIF-formated picture but just wondering if anyone have the experience to analyse ImageJ data using JPEG image? And how do we measure, say the diameter or area of our cells using ImageJ?
