However, there are many options to define your data and to change what parts of the analysis are run, and how they are run. You should look though the Command line options.
If you have any spaces in your file-path, please enclose it in quotation marks, otherwise cellfinder will interpret it as two inputs, separated by a space.
i.e. "/path/to/my data" not path/to/my data.
Retraining the machine learning network to classify cells
The deep learning network included with cellfinder to classify cells as real cells or artefacts was trained on a very specific dataset. You will very likely need to retrain this if the classification is incorrect on your data. See Training the network.
