SpikeInterface-GUI: efficient and versatile spike sorting visualization and curation

Extracellular electrophysiology is a key technique in neuroscience, but the scale and diversity of the produced data make it difficult to visualize. Additionally the rapid development of new spike sorting algorithms creates a significant challenge for researchers trying to assess and compare these tools. In this paper we introduce SpikeInterface-GUI, a flexible visualization tool tightly integrated with SpikeInterface, designed to display raw ephys data and information about spike sorted units. Researchers can utilize the GUI to curate output by labeling, merging and splitting units, and use a plugin system to create their own bespoke data visualizations. There are two backends, including a web-based backend designed to support deployment on a web-server or centralized workstation. When set up, this allows global collaborations to easily share and compare results on a web browser without having to install any software.
