Running cellfinder

cellfinder runs with a single command, with various arguments that are detailed in Command line options. To analyse the example data, the flags we need are:
-s The primary signal channel: test_brain/ch00
-b The secondary autofluorescence channel (or background): test_brain/ch01
-o The output directory :  test_brain/output
--orientation The data orientation: psl
-v The voxel spacing in the same order as the data orientation (psl): 5 2 2 
--atlas The atlas we want to use: allen_mouse_10um
If your machine has less than 32GB of RAM, you should use the allen_mouse_25um atlas either way, as registration with the high-resolution atlas requires about 30GB for this image.
Putting this all together into a single command gives:
1
cellfinder -s test_brain/ch00 -b test_brain/ch01 -o test_brain/output -v 5 2 2 --orientation psl --atlas allen_mouse_10um
Copied!
This command will take quite a long time (anywhere from 2-10 hours) to run, depending on:
The speed of the disk the data is stored on
The CPU speed and number of cores
The GPU you have
You'll know cellfinder has finished when you see something like this:
2020-10-14 00:07:20 AM - INFO - MainProcess main.py:86 - Finished. Total time taken: 3:22:42
If you just want to check that everything is working, we can speed everything up by:
Only analysing part of the brain using the flags: --start-plane 1500 --end-plane 1550
Using a lower-resolution atlas, using the flag: --atlas allen_mouse_25um
1
cellfinder -s test_brain/ch00 -b test_brain/ch01 -o test_brain/output -v 5 2 2 --orientation psl --atlas allen_mouse_25um --start-plane 1500 --end-plane 1550
Copied!
If your machine has less than 32GB of RAM, you should use the allen_mouse_25um atlas either way, as registration with the high-resolution atlas requires about 30GB for this image.
If the cell classification step takes a (very) long time, it may not be using the GPU. If you have an NVIDIA GPU, see Speeding up cellfinder to make sure that your GPU is set up properly.
Once cellfinder has run, you can go onto Visualising the results​
