Detailed Description

Fine calibration data for SSS.

A fine calibration file (.dat) contains one line per MEG sensor with: channel_number gain imbalance_x imbalance_y imbalance_z

Usage:

FineCalibration cal = FineCalibration::read("/path/to/sss_cal.dat");
cal.write("/path/to/output.dat");

Member Function Documentation

addEntry()

void UTILSLIB::FineCalibration::addEntry ( const FineCalEntry & entry )

inline

Add an entry.

Definition at line 132 of file fine_calibration.h.

entries()

const QList< FineCalEntry > & UTILSLIB::FineCalibration::entries ( ) const

inline

Get the calibration entries.

Definition at line 103 of file fine_calibration.h.

findEntry()

bool FineCalibration::findEntry	(	int	chNumber,
		FineCalEntry &	entry ) const

Find entry by channel number.

Parameters

[in]	chNumber	Channel number to find.
[out]	entry	Found entry (if any).

Returns

true if found.

Definition at line 110 of file fine_calibration.cpp.

gainVector()

VectorXd FineCalibration::gainVector

(

)

const

Build gain correction diagonal matrix for MEG channels.

Returns a diagonal matrix where each diagonal element is the gain factor for the corresponding MEG channel (in the order of m_entries).

Returns

Diagonal gain matrix (n_entries × n_entries).

Definition at line 123 of file fine_calibration.cpp.

imbalanceMatrix()

MatrixXd FineCalibration::imbalanceMatrix

(

)

const

Build imbalance matrix.

Returns a matrix of cross-talk imbalance vectors (n_entries × 3).

Definition at line 134 of file fine_calibration.cpp.

isEmpty()

bool UTILSLIB::FineCalibration::isEmpty ( ) const

inline

Check if empty.

Definition at line 115 of file fine_calibration.h.

read()

FineCalibration FineCalibration::read ( const QString & sPath )

static

Read a fine calibration file (.dat format).

Expected format: whitespace-separated columns per line: channel_number gain imbalance_x imbalance_y imbalance_z Lines starting with '#' are comments.

Parameters

[in]

sPath

Path to .dat file.

Returns

FineCalibration with loaded entries.

Definition at line 39 of file fine_calibration.cpp.

size()

int UTILSLIB::FineCalibration::size ( ) const

inline

Get the number of entries.

Definition at line 109 of file fine_calibration.h.

write()

bool FineCalibration::write

(

const QString &

sPath

)

const

Write fine calibration to a .dat file.

Parameters

[in]

sPath

Output file path.

Returns

true if successful.
