ssg_databrowse2d

PURPOSE ^

SSG_DATABROWSE2D Feature projection GUI in 2D (work in progress).

SYNOPSIS ^

function ssg_databrowse2d(spikes, assigns, show)

DESCRIPTION ^

 SSG_DATABROWSE2D  Feature projection GUI in 2D (work in progress).
     SSG_DATABROWSE(SPIKES) creates a 2-D databrowse figure.  Call with a
     spike sorting object SPIKES and an optional assignments vector whose length
     corresponds to the number of waveforms in the SPIKES structure.  If no
     assignments vector is specified, the function chooses the first of 
     {final, local, or none} clustering depending on which have been computed.
     Once the figure appears, you can:
         Click on the axis labels to change features.
         Click on a data point to bring the associated cluster to the front.
         Double-click outside of the axes to make a density snapshot of the current view.
