#include <mne/mne_meas_data_set.h>

class MNELIB::MNEMeasDataSet

Single measurement epoch or average within MNEMeasData.

Replaces *mneMeasDataSet / mneMeasDataSetRec from MNE-C mne_types.h. Holds the measured data matrix, optional projector / whitened / filtered copies, baseline values, and per-epoch metadata (number of averages, time range, etc.).

Public Methods​

MNEMeasDataSet()​

Constructs an empty measurement data set.

Refactored from mne_new_meas_data_set (mne_read_data.c).

~MNEMeasDataSet()​

Destroys the measurement data set and frees all owned C-style arrays.

Refactored from mne_free_meas_data_set (mne_read_data.c).

getValuesAtTime(time, integ, nch, use_abs, value)​

Pick signal values at a specified time point using linear interpolation.

Reads from the data matrix (time-by-time layout: data[sample][channel]) and writes interpolated values into the output array.

Refactored: mne_get_values_from_data (mne_get_values.c)

Parameters:

  • time : float Target time point (seconds).

  • integ : float Integration window width (seconds).

  • nch : int Number of channels to pick.

  • use_abs : bool If true, take absolute values before averaging.

  • value : *float ** Output array of picked values (nch elements).

Returns:

  • int — 0 on success, -1 on error.

Static Methods​

getValuesFromChannelData(time, integ, data, nsamp, nch, tmin, sfreq, use_abs, value)​

Pick signal values at a specified time point using linear interpolation (channel-major layout).

Reads from a channel-by-time data matrix (data[channel][sample]).

Refactored: mne_get_values_from_data_ch (mne_get_values.c)

Parameters:

  • time : float Target time point (seconds).

  • integ : float Integration window width (seconds).

  • data : *float *** Data matrix (channel-by-time layout).

  • nsamp : int Number of time samples.

  • nch : int Number of channels.

  • tmin : float Time of first sample (seconds).

  • sfreq : float Sampling frequency (Hz).

  • use_abs : bool If true, take absolute values before averaging.

  • value : *float ** Output array of picked values (nch elements).

Returns:

  • int — 0 on success, -1 on error.
