Hi Jack,

An alternative to import an MF4 file in MATLAB without using the "mdfRead" function from the Vehicle Network Toolbox is to use the "mdfreader" Python library, found at the following link: https://pypi.org/project/mdfreader/

Once you install both Python and this "mdfreader" library, you can call Python functionality of this library directly from MATLAB by adding the "py." prefix to the name of the Python function that you want to call. For example, to read an MF4 file:

mdfobj=py.mdfreader.Mdf('VehicleData.mf4')

Now this "mdfobj" object can be worked with using functions from the "mdfreader" library to get the required data from the MF4 file.

Kindly refer to the following links for more information:

Hope this helps!
