Apply inverse operator to EpochsTFR.

epochs_tfrEpochsTFR object

Single trial, phase-amplitude (complex-valued), time-frequency epochs.

inverse_operatorlist of dict | dict

The inverse operator for each frequency or a single inverse operator to use for all frequencies.


The regularization parameter.

method“MNE” | “dSPM” | “sLORETA” | “eLORETA”

Use minimum norm, dSPM (default), sLORETA, or eLORETA.

labelLabel | None

Restricts the source estimates to a given label. If None, source estimates will be computed for the entire source space.


Number of averages used to regularize the solution. Set to 1 on single Epoch by default.

pick_oriNone | “normal” | “vector”


  • None

    Pooling is performed by taking the norm of loose/free orientations. In case of a fixed source space no norm is computed leading to signed source activity.

  • "normal"

    Only the normal to the cortical surface is kept. This is only implemented when working with loose orientations.

  • "vector"

    No pooling of the orientations is done, and the vector result will be returned in the form of a mne.VectorSourceEstimate object.


Return a generator object instead of a list. This allows iterating over the stcs without having to keep them all in memory.


If True, do not call prepare_inverse_operator().

method_paramsdict | None

Additional options for eLORETA. See Notes of apply_inverse().


Whether to use cortical patch statistics to define normal orientations for surfaces (default True).

Only used when the inverse is free orientation (loose=1.), not in surface orientation, and pick_ori='normal'.

verbosebool | str | int | None

Control verbosity of the logging output. If None, use the default verbosity level. See the logging documentation and mne.verbose() for details. Should only be passed as a keyword argument.

stcslist of list of (SourceEstimate | VectorSourceEstimate | VolSourceEstimate)

The source estimates for all frequencies (outside list) and for all epochs (inside list).
