I have a set of 900k particles, which I extracted at 352px and downscaled to 196px. Pixel size 0.85A/px.
My 2D classification failes if I increase the number of classes. 300 still works, 400 fails. Downscaling further to 48px doesn’t solve the problem.
The micrographs are located at a mounted server.
Any idea what is causing the error and how to resovle it?
