Dear Mne users,

is there in MNE python a way to interactively plot
the raw data as in mne_browse_raw?

If I use raw.plot() is there a way to visualize the
intensity of the magnetic field?

I'm applying ICA to a raw dataset and I'm using this
reject dict
reject = dict(mag=4e-12, grad=4000e-13)

but ICA doesn't perform and I get this message

RuntimeError: No clean segment found. Please consider updating your
rejection thresholds

since I'm asking how inspect the raw data by MNE python to see how to set
the reject thresholds.

Thks!
best

Hi Annalisa,

If I use raw.plot() is there a way to visualize the
intensity of the magnetic field?

What do you mean? It should give you the MEG field amplitudes.

RuntimeError: No clean segment found. Please consider updating your

rejection thresholds

It means that your reject parameters are too strict. You want to make sure
that data segments contaminated by strong environmental magnetic fields are
ignored, but you don't want to reject ECG or EOG since these need to be
kept in order to find corresponding components.

Try dict(mag=5e-12, grad=5000e-13)

What is wrong with raw.plot()?
It should give you exactly what you want.

I hope this helps,
Denis
