Beginner's guide to Fiji/ImageJ:
Excellent guide to Fiji available here written by Cameron Nowell. Includes how to setup Fiji, opening images, adjusting brightness/contrast, scale bars, colour channels, opening different image formats, simple analysis (e.g. intensity measurements and cell counting), batch processing, and more complicated analysis. Also available here as a PDF.

Self paced worksheets for learning image analysis in Fiji
The aim of this course is not to teach python, but to give you an idea of how it can be used for image analysis.
To get started:
-

-
Experienced Python users: Set up a virtual or conda environment with Python 3.9. Within the environment please
install napariLink opens in a new windowLink opens in a new window (I use ​python -m pip install napari[all], check the instructions for your operating system if you have issues). I use jupyter notebooks but you can use your favourite IDE instead. After activating the environment, please check you can run the SetupCheck.py script (or SetupCheck.ipynb if using jupyter notebook) from the attached .zip folder.
You should get a Napari window that opens and looks like the picture SetupCheck.png.
Attempt the CAMDU Challenge in Fiji or Python:
Consolidate your skills by trying them out on this challenge. Download the
data set provided. The data set contains six microscopy images (.tif files), each with three channels: in the first, you have a a GFP-tagged protein of interest, which forms foci; on the second a cytoplasmic marker; and on the third a brightfield image of the cells.
You can try to write a code to do one or all of the following:
- Identify the cell boundaries (channel two only, use only the most in focus plane)
- Detect the foci (channel one only, use a maximum projection)
- Count the foci in specific cells - combining the first two codes
- Create a code to batch process all the files in the data set.
