class MNELIB::MNEMeasData

Measurement data container for MNE inverse and dipole-fit computations.

Replaces *mneMeasData / mneMeasDataRec from MNE-C mne_types.h. Holds channel information, coordinate transforms, projection operators, and one or more [MNEMeasDataSet](/docs/api/mne/mne-meas-data-set) epochs loaded from a FIFF evoked-response file.

Public Methods​

MNEMeasData()​

Constructs an empty measurement data container.

Refactored from mne_new_meas_data (mne_read_data.c).

~MNEMeasData()​

Destroys the measurement data and all owned data sets.

Refactored from mne_free_meas_data (mne_read_data.c).

adjust_baselines(bmin, bmax)​

Adjust baseline offset of the current data set.

Subtracts the mean over [bmin, bmax] from every channel and accumulates the offset in MNEMeasDataSet::baselines.

Refactored from mne_adjust_baselines (mne_apply_baselines.c).

Parameters:

  • bmin : float Baseline window start (seconds).

  • bmax : float Baseline window end (seconds).

Static Methods​

mne_read_meas_data_add(name, set, op, fwd, namesp, nnamesp, add_to)​

Read an evoked-response data set and append it to an existing container.

If add_to is nullptr a new MNEMeasData is created; otherwise the loaded epoch is appended to add_to's set list.

Refactored from mne_read_meas_data_add (mne_read_data.c).

Parameters:

  • name : const QString & Path to the FIFF measurement file.

  • set : int 1-based data-set index to load.

  • op : *MNEInverseOperator ** Inverse operator for consistency checks (may be nullptr).

  • fwd : *MNENamedMatrix ** Forward operator for consistency checks (may be nullptr).

  • namesp : const QStringList & Explicit channel name list (fallback if op and fwd are nullptr).

  • nnamesp : int Number of entries in namesp.

  • add_to : *MNEMeasData ** Existing container to append to, or nullptr to create a new one.

Returns:

  • *MNEMeasData ** — Pointer to the (new or existing) container, or nullptr on failure.

mne_read_meas_data(name, set, op, fwd, namesp, nnamesp)​

Read an evoked-response data set into a new container.

Convenience wrapper around mne_read_meas_data_add() with add_to = nullptr.

Parameters:

  • name : const QString & Path to the FIFF measurement file.

  • set : int 1-based data-set index to load.

  • op : *MNEInverseOperator ** Inverse operator for consistency checks (may be nullptr).

  • fwd : *MNENamedMatrix ** Forward operator for consistency checks (may be nullptr).

  • namesp : const QStringList & Explicit channel name list.

  • nnamesp : int Number of entries in namesp.

Returns:

  • *MNEMeasData ** — Pointer to the new container, or nullptr on failure.
