Hello,

Is there a quick guide for how to create the principal components/ops.wPCA from your own data? In the config files these lines are shown:

% options for initializing spikes from data		
ops.initialize      = 'fromData';    %'fromData' or 'no'		

% load predefined principal components (visualization only (Phy): used for features)		
% dd                  = load('PCspikes2.mat'); % you might want to recompute this from your own data		
% ops.wPCA            = dd.Wi(:,1:7);   % PCs 		

but I can't find any documentation that explains how to create your own dd.Wi (nor why it only slices the first 7 components).

Thanks!,
Dustin
