+The raw data in Axona format was compressed using 7-zip. It includes one folder per animal with position (.pos), one eeg per tetrode (.egfx), setup file (.set) and logfiles related to car speeds and timestamps (.log). Tetrodes are 1-4 and egf correspond to hippocampal data, while terrodes 5-8 (egf2) and 9-12 (egf3) correspond to entorhinal tetrodes. Filenames contain the date and trial number with the format YYMMDDTT.x.
