Convert Axion data

Data generated from an Axion Biosystems MEA will be saved in the .raw format. Unfortunately, it is not possible to open this format in Python. For the MEA-library to analyse these files, they must first be converted to the hdf5 format. The only way to do so, is to read the .raw files in MATLAB using the AxionFileLoader. This repository must first be downloaded and added to the MATLAB path.

For the file conversion, a script is available in the github repository. This script will read the raw voltage data from the file, and save them in a new hdf5 file. After this, the hdf5 file can be analysed by MEAlytics. For this script to work, the AxionFileLoader must be installed in MATLAB.

After the conversion has been completed, these files are not compressed yet, and might take up a lot of storage space. Hdf5 files can be compressed using the GUI (see Compress/Rechunk files) or using h5repack
