class MNELIB::MNEProjItem

A single SSP (Signal-Space Projection) item.

MNEProjItem holds one linear projection operator consisting of a set of projection vectors (stored as an MNENamedMatrix), together with metadata such as the projection kind, a human-readable description, and flags indicating whether the item is currently active and which channel types (MEG / EEG) it covers.

Projection items are aggregated by MNEProjOp to form the complete SSP operator that is applied during inverse computations and dipole fitting.

Public Methods​

MNEProjItem()​

Default constructor.

Initialises all flags to their default values (active = true, kind = FIFFV_PROJ_ITEM_NONE, no MEG/EEG channels).

MNEProjItem(other)​

Copy constructor.

Deep-copies the projection vectors (unique_ptr member).

operator=(other)​

Copy assignment operator.

Deep-copies the projection vectors (unique_ptr member).

MNEProjItem()​

Move constructor (defaulted).

operator=()​

Move assignment operator (defaulted).

~MNEProjItem()​

Destructor.

affect(list, nlist)​

Test whether this projection item affects any of the listed channels.

Iterates over list and checks if any channel name matches a column in the projection vectors that contains at least one non-zero entry.

Parameters:

  • list : const QStringList & Channel names to test against.

  • nlist : int Number of channel names in list.

Returns:

  • int — true (non-zero) if this item affects at least one channel, false (0) otherwise.
