Constructor & Destructor Documentation

◆ FiffEvoked() [1/3]

FiffEvoked::FiffEvoked ( )

Constructs a fiff evoked data.

Definition at line 60 of file fiff_evoked.cpp.

◆ FiffEvoked() [2/3]

FiffEvoked::FiffEvoked	(	QIODevice &	p_IODevice,
		QVariant	setno = 0,
		QPair< float, float >	t_baseline = defaultFloatPair,
		bool	proj = true,
		fiff_int_t	p_aspect_kind = FIFFV_ASPECT_AVERAGE )

Constructs fiff evoked data, by reading from a IO device.

Parameters

[in]	p_IODevice	IO device to read from the evoked data set.
[in]	setno	The set to pick. Dataset ID number (int) or comment/name (str). Optional if there isonly one data set in file.
[in]	t_baseline	The time interval to apply rescaling / baseline correction. If None do not apply it. If baseline is (a, b). the interval is between "a (s)" and "b (s)". If a is None the beginning of the data is used and if b is None then b is set to the end of the interval. If baseline is equal ot (None, None) all the time interval is used. If None, no correction is applied.
[in]	proj	Apply SSP projection vectors (optional, default = true).
[in]	p_aspect_kind	Either "FIFFV_ASPECT_AVERAGE" or "FIFFV_ASPECT_STD_ERR". The type of data to read. Only used if "setno" is a str.

Definition at line 72 of file fiff_evoked.cpp.

◆ FiffEvoked() [3/3]

FiffEvoked::FiffEvoked ( const FiffEvoked & p_FiffEvoked )

Copy constructor.

Parameters

[in] p_FiffEvoked Fiff evoked data which should be copied.

Definition at line 89 of file fiff_evoked.cpp.

◆ ~FiffEvoked()

FiffEvoked::~FiffEvoked ( )

Destroys the FiffEvoked.

Definition at line 106 of file fiff_evoked.cpp.

Member Function Documentation

◆ applyBaselineCorrection()

void FiffEvoked::applyBaselineCorrection ( QPair< float, float > & p_baseline )

Applies baseline correction to the evoked data.

Parameters

[in] p_baseline time definition of the baseline in seconds [from, to].

Definition at line 569 of file fiff_evoked.cpp.

◆ aspectKindToString()

QString FIFFLIB::FiffEvoked::aspectKindToString ( ) const

inline

Provides the python Evoked string formatted aspect_kind, which is stored in kind: "average" <-> FIFFV_ASPECT_AVERAGE, "standard_error" <-> FIFFV_ASPECT_STD_ERR or "unknown"

Returns: string formatted aspect_kind.

Definition at line 247 of file fiff_evoked.h.

◆ ch_names()

QStringList FIFFLIB::FiffEvoked::ch_names ( )

inline

Returns list of channel names stored in fiff info -> this is to stay consistent with python

Definition at line 240 of file fiff_evoked.h.

◆ clear()

void FiffEvoked::clear ( )

Initializes fiff evoked data.

Definition at line 113 of file fiff_evoked.cpp.

◆ isEmpty()

bool FIFFLIB::FiffEvoked::isEmpty ( ) const

inline

Returns whether FiffEvoked is empty.

Returns: true if is empty, false otherwise.

Definition at line 259 of file fiff_evoked.h.

◆ operator+=()

FiffEvoked & FiffEvoked::operator+= ( const Eigen::MatrixXd & newData )

Inputs a new data set and recalculates the average. This function also iterates the nave parameter by one.

Parameters

[in] newData the new data set which is to be added to the current average.

Returns: the updated FiffEvoked.

Definition at line 542 of file fiff_evoked.cpp.

◆ pick_channels()

FiffEvoked FiffEvoked::pick_channels	(	const QStringList &	include = defaultQStringList,
		const QStringList &	exclude = defaultQStringList ) const

fiff_pick_channels_evoked

MNE toolbox root function

Pick desired channels from evoked-response data

Parameters

[in]	include	- Channels to include (if empty, include all available).
[in]	exclude	- Channels to exclude (if empty, do not exclude any).

Returns: the desired fiff evoked data.

Definition at line 128 of file fiff_evoked.cpp.

◆ read()

bool FiffEvoked::read	(	QIODevice &	p_IODevice,
		FiffEvoked &	p_FiffEvoked,
		QVariant	setno = 0,

[in]	setno	the set to pick. Dataset ID number (int) or comment/name (str). Optional if there isonly one data set in file.
[in]	t_baseline	The time interval to apply rescaling / baseline correction. If None do not apply it. If baseline is (a, b). the interval is between "a (s)" and "b (s)". If a is None the beginning of the data is used and if b is None then b is set to the end of the interval. If baseline is equal ot (None, None) all the time interval is used. If None, no correction is applied.
[in]	proj	Apply SSP projection vectors (optional, default = true).
