MNE users: is it possible to supply mne_simu with a complete, tabulated times course (time series with every time sample represented), instead of an expression? I wish to make a complicated set of interrelated (by correlation and/or coherence) time-courses that are not possible to specify with the expression method given.
I am not very familiar with that tool, but if you want to do very
specific simulations, the best way to do this would be using either the
MATLAB toolbox (in either MATLAB or octave) or MNE-Python. You can
simply read the forward solution and multiply the simulated data (adding
whatever noise you like from whichever sources you prefer). This will
give you the most control over all aspects of the simulations.
