Details

SIGNAL_TYPES has the following options: 'LFP', 'Spike', 'EKG', 'Audio', 'Photodiode', or 'Unknown'. As of 'raveio' 0.0.6, only 'LFP' (see LFP_electrode) signal type is supported.

LOCATION_TYPES is a list of the electrode location types: 'iEEG' (this includes the next two), 'sEEG' (stereo), 'ECoG' (surface), 'EEG' (scalp), 'Others'. See field 'location' in RAVEAbstarctElectrode

MNI305_to_MNI152 is a 4-by-4 matrix converting 'MNI305' coordinates to 'MNI152' space. The difference of these two spaces is: 'MNI305' is an average of 305 human subjects, while 'MNI152' is the average of 152 people. These two coordinates differs slightly. While most of the 'MNI' coordinates reported by 'RAVE' and 'FreeSurfer' are in the 'MNI305' space, many other programs are expecting 'MNI152' coordinates.
