Functions that need to be extended for this to work ft_filetype ft_read_header, ft_read_data, ft_read_event ft_read_sens (by means of ft_read_header?) ft_senstype ft_chantype ft_chanunit Since NetMEG does not define new MEG acquisition systems but rather contains data from existing ones, it should be checked that ft_senstype detects the original acquisition system correctly. The checks for full compatibility could be done similar how the checks will have to be implemented for the Triux system (see bug #1356).

please note that part of the work has already started and that some support is already in place. However, the precise status at this moment is not clear, nor is the work that still needs to be done. One thing that for sure has to be done is to make a test script (or a bunch of them) that checks that the reading functions work as expected.

Should we consider also supporting NetMEG in the ft_write_data function, i.e. export data from MATLAB to NetMEG files?
