eelbrain.pipeline.RawSource

class eelbrain.pipeline.RawSource(sysname=None, rename_channels=None, montage=None, adjacency=None, **kwargs)

Raw data source

Parameters:

• sysname (str) – Used to determine sensor positions (not needed for KIT files, or when a montage is specified).

• rename_channels (dict) – The names the montage uses for channels in the data, as a {data_name: montage_name} dictionary. The montage is renamed accordingly before it is applied, so that channel names in the data (as defined by the BIDS dataset) are never modified. If adjacency is a builtin adjacency name, its channels are renamed in the same way. Useful when the data uses a naming convention different from a standard montage.

• montage (str | mne.channels.DigMontage) – Montage that is applied to raw data to set sensor positions (see mne.io.Raw.set_montage()), as a standard montage name (see mne.channels.make_standard_montage()) or mne.channels.DigMontage instance.

• adjacency (str | list[tuple[str, str]] | Path) –

  Adjacency between sensors. Can be specified as:

  • 'auto' to use mne.channels.find_ch_adjacency()

  • Pre-defined adjacency (one of mne.channels.get_builtin_ch_adjacencies())

  • Path to load adjacency from a file

  • "none" for no connections

  • "grid" for grid connections

  • list of connections (e.g., [('OZ', 'O1'), ('OZ', 'O2'), ...])

  • numpy.ndarray of int, shape (n_edges, 2), to specify connections in terms of indices. Each row should specify one connection [i, j] with i < j. If the array’s dtype is uint32, property checks are disabled to improve efficiency.

  If unspecified, it is inferred from sysname if possible. When using rename_channels, only a builtin adjacency name is translated to data channel names; an adjacency specified as a file or as an explicit list of connections must already use the channel names in the data (edges with unknown channel names are silently dropped).
