Detailed Description

Pure I/O helpers that load MNE data files and return results.

These static methods have zero coupling to the widget layer. BrainView calls them to obtain data and then wires the results into its own model / surface map / member state.

loadDipoles()

InvEcdSet DISP3DLIB::DataLoader::loadDipoles ( const QString & dipPath )

static

Load dipole set from a .dip file.

Parameters

[in]

dipPath

Path to the dipole file.

Returns

The loaded InvEcdSet (may be empty on failure).

Definition at line 312 of file dataloader.cpp.

loadEvoked()

FiffEvoked DISP3DLIB::DataLoader::loadEvoked ( const QString & evokedPath, int aveIndex = 0 )

static

Load an FiffEvoked from a FIF file.

Parameters

[in]	evokedPath	Path to the FIF file.
[in]	aveIndex	Set index to load.

Returns

The loaded FiffEvoked (may be empty on failure).

Definition at line 363 of file dataloader.cpp.

loadHeadToMriTransform()

bool DISP3DLIB::DataLoader::loadHeadToMriTransform ( const QString & transPath, FIFFLIB::FiffCoordTrans & trans )

static

Load the Head ↔ MRI transformation from a FIF file and normalise it to Head → MRI orientation. Other transforms in the file are ignored.

Parameters

[in]	transPath	Path to the FIF file.
[out]	trans	The resulting transform (Head → MRI).

Returns

true on success; false if the file holds no Head ↔ MRI transform.

Definition at line 353 of file dataloader.cpp.

loadHelmetSurface()

std::shared_ptr< BrainSurface > DISP3DLIB::DataLoader::loadHelmetSurface ( const QString & helmetFilePath, const QMatrix4x4 & devHeadTrans = QMatrix4x4(), bool applyTrans = false )

static

Load a standalone MEG helmet surface from a BEM FIF file.

Parameters

[in]	helmetFilePath	Path to the helmet BEM FIF file.
[in]	devHeadTrans	Device-to-Head transformation matrix (identity if none).
[in]	applyTrans	Whether to apply the dev→head transform.

Returns

Shared pointer to the loaded BrainSurface, or nullptr on failure.

Definition at line 259 of file dataloader.cpp.

loadSensors()

DataLoader::SensorLoadResult DISP3DLIB::DataLoader::loadSensors ( const QString & fifPath, const QString & megHelmetOverridePath = {} )

static

Load sensor channels, digitizer points and MEG helmet from a FIF file.

Parameters

[in]	fifPath	Path to the FIF file.
[in]	megHelmetOverridePath	Optional override for the helmet surface file.

Returns

Populated SensorLoadResult.

Definition at line 46 of file dataloader.cpp.

loadSourceSpace()

MNESourceSpaces DISP3DLIB::DataLoader::loadSourceSpace ( const QString & fwdPath )

static

Load source space from a forward-solution FIF file.

Parameters

[in]

fwdPath

Path to the FIF file with source space.

Returns

The loaded source space (may be empty on failure).

Definition at line 323 of file dataloader.cpp.

probeEvokedSets()

QStringList DISP3DLIB::DataLoader::probeEvokedSets ( const QString & evokedPath )

static

Probe a FIF file for the available evoked data sets.

Parameters

[in]

evokedPath

Path to the FIF file.

Returns

List of human-readable labels for each set.
