Detailed Description

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.).

Constructor & Destructor Documentation

◆ MNEMeasDataSet()

MNEMeasDataSet::MNEMeasDataSet ( )

Constructs an empty measurement data set.

Refactored from mne_new_meas_data_set (mne_read_data.c).

Definition at line 59 of file mne_meas_data_set.cpp.

◆ ~MNEMeasDataSet()

MNEMeasDataSet::~MNEMeasDataSet ( )

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

Refactored from mne_free_meas_data_set (mne_read_data.c).

Definition at line 71 of file mne_meas_data_set.cpp.

Member Function Documentation

◆ getValuesAtTime()

int MNEMeasDataSet::getValuesAtTime	(	float	time,
		float	integ,
		int	nch,
		bool	use_abs,
		float *	value ) const

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

[in]	time	Target time point (seconds).
[in]	integ	Integration window width (seconds).
[in]	nch	Number of channels to pick.
[in]	use_abs	If true, take absolute values before averaging.
[out]	value	Output array of picked values (nch elements).

Returns: 0 on success, -1 on error.

Definition at line 77 of file mne_meas_data_set.cpp.

◆ getValuesFromChannelData()

int MNEMeasDataSet::getValuesFromChannelData	(	float	time,
		float	integ,
		float **	data,
		int	nsamp,
		int	nch,
		float	tmin,
		float	sfreq,
		bool	use_abs,
		float *	value )

static

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

[in]	time	Target time point (seconds).
[in]	integ	Integration window width (seconds).
[in]	data	Data matrix (channel-by-time layout).
[in]	nsamp	Number of time samples.
[in]	nch	Number of channels.
[in]	tmin	Time of first sample (seconds).
[in]	sfreq	Sampling frequency (Hz).
[in]	use_abs	If true, take absolute values before averaging.
[out]	value	Output array of picked values (nch elements).

Returns: 0 on success, -1 on error.
