Plotting/visualizing .spikes files into Matlab

[pauliehage]

Hello,

Im interested in the spike sorting feature of Open Ephys for upcoming neuro phys experiments -

Currently, Ive been able to setup a practice signal chain of the following:
File read (cortex file) > Bandpass (300-6000hz) > Spike Sorter to get the hang of using the OpenEphys software.

Im able to successfully set some arbitrary thresholds and record the signal - to then load the '.spikes' file of a particular channel into matlab.

Problem: Im attempting to visualize/analyze/plot the spike data and have no idea how to proceed. Upon loading the data, a 30x40x2 array is created. Im unsure how to perceive the contents of this array, what the values correspond to, and how to plot them in a manner that allows me to see the spikes as well as any other data that is usually acquired via the spike sorter.

Any information/elaboration/tutorial would be tremendous as I am a beginner attempting to learn this software.

Thank you very much.
