mvpa2.misc.io.base.SensorLocations

class mvpa2.misc.io.base.SensorLocations(*args, **kwargs)

Base class for sensor location readers.

Each subclass should provide x, y, z coordinates via the pos_x, pos_y, and pos_z attrbibutes.

Axes should follow the following convention:

x-axis: left -> right y-axis: anterior -> posterior z-axis: superior -> inferior

Attributes

ncolumns	Returns the number of columns.
nrows	Returns the number of rows.
