Before trying to troubleshoot, cellfinder can be slow. Even on a very good desktop computer, a full analysis of a labelled mouse brain with many thousands of cells can take between 4-12 hours.
Annoying advice, but a bigger, better computer will likely speed up cellfinder. See system requirements
If your data is on a "normal" spinning hard drive, and you have a solid-state drive (SSD) available, putting your data on there will likely speed things up.
If your data is on a network drive (microscopy facility server, institutional file storage etc.), consider moving it to your local machine first.
If you're using a compute cluster, there is likely to be a specific fast data storage area for this, maybe called "Scratch". Ask your sysadmins for help
These steps may be slow if cellfinder is not properly using the GPU. If you have followed the instructions in setting up your GPU, you may need to check that everything is configured properly:
Open a terminal (or Anaconda Prompt):
Check that tensorflow can use the GPU
import tensorflow as tftf.test.is_gpu_available()
If you see something like this, then all is well.

Then your GPU is not properly configured. If you have followed everything in setting up your GPU, please go speak to whoever administers your machine. If you're still stuck get in touch, but there is a limited amount we can do to help configure your system.
