Parse FieldTrip neighbors .mat file.
More information on these neighbor definitions can be found on the related FieldTrip documentation pages.
The file name. Example: ‘neuromag306mag’, ‘neuromag306planar’, ‘ctf275’, ‘biosemi64’, etc.
Channels to include. Slices and lists of integers will be interpreted as channel indices. In lists, channel type strings (e.g.,
['meg', 'eeg']) will pick channels of those types, channel name strings (e.g.,
['MEG0111', 'MEG2623']will pick the given channels. Can also be the string values “all” to pick all channels, or “data” to pick data channels. None (default) will pick all channels. Note that channels in
info['bads']will be included if their names or indices are explicitly provided. Picks Must match the template.
This function is closely related to
find_ch_adjacency(). If you don’t know the correct file for the neighbor definitions,
find_ch_adjacency()can compute the adjacency matrix from 2d sensor locations.
