mne.read_epochs_fieldtrip(fname, info, data_name='data', trialinfo_column=0)[source]

Load epoched data from a FieldTrip preprocessing structure.

This function expects to find epoched data in the structure data_name is pointing at.


Only epochs with the same amount of channels and samples are supported!


FieldTrip does not normally store the original information concerning channel location, orientation, type etc. It is therefore highly recommended to provide the info field. This can be obtained by reading the original raw data file with MNE functions (without preload). The returned object contains the necessary info field.

fname: str

Path and filename of the .mat file containing the data.

info: dict or None

The info dict of the raw data file corresponding to the data to import. If this is set to None, limited information is extracted from the FieldTrip structure.

data_name: str

Name of heading dict/ variable name under which the data was originally saved in MATLAB.

trialinfo_column: int

Column of the trialinfo matrix to use for the event codes

epochs: instance of EpochsArray

An EpochsArray containing the loaded data.
