Allego

Allego is the Radiens acquisition app: it controls the data acquisition system, records trials, and shows the recording as it happens, with signal-quality metrics per channel, probe- and brain-centered views, and spike sorting and PSTH computed in real time.

Allego provides instrument control for XDAQ ↗, Smartbox ↗ and SiNAPS, configuring the headstage chip's sampling rate and filters, the probe model and the channel map, and reads any other acquisition stream live, with no driver, as the recording is written by Intan, Open Ephys, SpikeGLX, TDT or Plexon systems. The real-time monitoring package, Vantage, is the reason to run it: live traces, per-channel signal quality, power spectra, stimulus-artifact removal at the rig, and at Pro live spectral analysis, live spike sorting and live PSTH, so a failed site, a poor reference or a loose connector is seen in the first minutes of a session, while the animal is still on the rig and the problem can be fixed.

A recording in Allego is a trial, one Record start-to-stop saved as one data file, with the subject, probe, headstage, sampling rate, filter settings and channel map written with it; GPIO ↗ signals from the DAQ are recorded as channels in the same trial. Starting, stopping and adjusting a recording is session control. Everything Allego does in the GUI can be scripted with RadiensPy and the Radiens CLI, and the files it writes open directly in Videre. Allego runs on Windows, macOS and Linux; the Standard edition is free.
