Videre

Videre is the Radiens analysis app: it opens a recording in place, from any supported format and with no conversion, plays it back in linked views (raw traces, probe-centered and brain-centered heatmaps) and runs spike sorting, PSTH, spectral analysis and spatial-temporal field analysis on it, and each result keeps its provenance.

Videre reads the vendor formats of Intan, SpikeGLX, Open Ephys, TDT and Plexon, Kilosort and Phy outputs, and NWB, which it also writes, so data recorded on any system and sorted with any pipeline are analyzed in one place without a translation step. Signal and quality metrics are computed continuously across a file, and the probe model, native for NeuroNexus, SiNAPS and Neuropixels probes and built with the model builder for others, places every channel on the electrode and in the brain, which is what makes the heatmap views and current-source density possible. Filtering, re-referencing, downsampling and slicing are transforms applied to a dataset, singly or in bulk, as reusable protocols; the result keeps its unique ID and provenance list, and analyses run on version-pinned open-source pipelines, so a figure can be re-derived from the recording it came from.

Videre is the second half of one act of seeing: what Allego shows live, Videre examines after the fact over the same data, and a trial recorded in Allego opens in Videre as it is. Everything in the GUI can be scripted with RadiensPy, and study-scale jobs run through Radiens Compute from a workstation to an on-demand cluster. Videre runs on Windows, macOS and Linux; the Standard edition is free.
