SFig19b1,19b2: unit-by-unit adjacency matrix element values ordered as in SFig19b 
SFig19b1 (unmasked adjacency matrix) is too large to be saved as .csv files, it will be uploaded to the data repository.
SFig19d: waveform of the 6 units (sheets) labelled as in SFig19d. 
SFig19j: standard hierarchical clustering tree output in the format of matlab function linkage() output Z varibale.  "(m – 1)-by-3 matrix, where m is the number of observations in the original data. Columns 1 and 2 of Z contain cluster indices linked in pairs to form a binary tree. Z(I,3) contains the linkage distance between the two clusters merged in row Z(I,:)." https://www.mathworks.com/help/stats/linkage.html
