Scripts for image processing are stored in the DigitalImageProcessing directory, and those for MEG data processing and data visualization are in the DataAnalysis directory.

Processing flow and the names of scripts used in each processing step are described in "ProcessingWorkflow.txt" in the DataAnalysis directory.
