SFig1a-1: each column is one row of waveforms (serialized) in one waveform blocks in (black rectangles in SFig1a)
each waveform is 40 pts
SFig1a-2: for the bubble plots, rows are neurons, columns are features in the order of 2d coordinates X, Y, amplitude, firing rate. 
SFig1b: spatial bins (rows) by 15 days (1 to 15 left to right)
SFig1c-e: neurons (rows) by 15 days (1 to 15 left to right), empty entries not used
SFig1f_waveforms: each sheet is one unit's waveform in one day, from 6 channels (rows), each of 40 pts in length (columns), channels ordered from top left, top right to bottom left, bottom right. 
SFig1f-2:  2d coordinates X, Y, by 15 days (day1 to 15, up to down).
SFig1g-ISIdist: each row is one neuron. 
SFig1g-waveform-location: each row is one unit pair.
