ChannelSubset

Select a subset of channels to retain.

Different indexing schemes are supported, including regularly spaced indices, random subset, and spatially equidistant subset. Version 0.5.0

indexing

Indexing scheme. Regular uses regularly spaced indexes (i.e., channel 1, 3, 5, etc), equidistant uses channels that are maximally evenly spaced in 3d (requires channel positions to be set), and random uses a pseudo-random subset of channels. Depending on how the headset channels are ordered, regular can give less even results than random in unlucky cases.
