Electrophysiology software that meets you where you are.
Radiens is NeuroNexus's electrophysiology software. It makes it easy to see what's in your recordings and rely on what you find — ready to use out of the box, and open to Python and the command line when your work calls for it. One program from recording to result, on your own data, working with most recording systems.
Meets you where you are.
Most labs assemble recording, analysis, and automation from separate tools — and pay for it in glue code, lost history, and time spent on software instead of science. Radiens is one program across the whole job, and it adapts to you.
Ready to use, or scriptable
Turnkey out of the box, and open to Python and the command line when your work calls for it.
A first-year student or a power user
The same program serves someone on their first day and someone writing their own pipelines.
One rig or a whole lab
From a single setup to a lab full of them — one system to learn, train on, and standardize.
Your data, most systems, free to start
Runs on your own storage, reads most recording systems, and the Standard tier plus the Python and command-line tools are free.
Spend your time on the science, not the software.
Electrophysiology has a way of making you fight your software. The recordings are dense binary files you can't easily look inside. The tools don't talk to each other, so you write scripts to move data between them — and then you have to maintain those scripts. Every hour spent on that plumbing is an hour not spent on the biology. Radiens is built to take that work off your plate: one program that records, shows, and analyzes your data, ready to use when that is all you need and open to code when it isn't — so the software gets out of the way and the science comes forward.
The parts of Radiens
Allego
RecordingRecord your experiment and watch the signal as it happens. Allego keeps signal quality in view the whole time (Vantage™), so you can catch a problem and fix it while the session is still live — instead of discovering it afterward, when the session is already spent.
Live view of every channel, with a signal-quality readout (Vantage™)
Real-time spike sorting and peri-stimulus histograms
Works with NeuroNexus hardware, SiNAPS, and Neuropixels
Records up to 1,024+ channels
Videre
AnalysisTurn recordings into results. Videre opens data from most systems — live or after the fact — and shows dense recordings as clear visual views, so structure is easy to see. It does the standard analyses every lab needs, and hands off cleanly to your other tools.
Spike sorting and spike-train analysis, with quality metrics
LFP, spectral, and depth-resolved field analysis
Probe- and brain-registered views of dense recordings
Reads a recording on most systems as it is written — no driver
Export to the open NWB standard
Radiens Compute
The analysis engineThe engine behind Videre, RadiensPy, and the command-line tool. It runs the same analyses reproducibly against your own storage — on your workstation today, with on-demand cluster and GPU compute in development.
The same analyses, run reproducibly and re-derivably
Runs on your workstation, against your own storage — nothing uploaded
The engine RadiensPy and the command-line tool drive
On-demand cluster and GPU compute — in development
RadiensPy & the command-line tool
Python and the command line · freeWhen you want to automate, everything the apps do is available from Python and the command line — free, at every tier. Work a routine out in the app, then run it across many sessions with a short, readable script. The command-line tool returns structured output, so it fits into your pipelines and works with AI agents.
RadiensPy — a free Python client with the same capabilities as the apps
Command-line tool — structured output, runs headless, works with agents
Works alongside SpikeInterface, MNE, and your own code
Free at every tier

Frequently asked questions
What is Radiens?
Radiens is NeuroNexus's electrophysiology software. It records, displays, and analyzes spike, LFP, EEG, and ECoG data from most recording systems — one program from recording to result.
What are the parts of Radiens?
Radiens includes Allego for recording, Videre for analysis, the Radiens Compute engine behind them, the free RadiensPy Python client and command-line tool, and Radiens Web for checking in from a browser.
Do I need to know how to program to use Radiens?
No. Radiens works out of the box through its apps — a first-year student can record and analyze without writing any code. When you want to automate or scale up, the same capabilities are available in Python and from the command line, so the program grows with you.
Does Radiens work with my current tools and recording system?
Yes. Radiens reads data from most systems — Intan, SpikeGLX, Open Ephys, TDT, Plexon, and common EEG/ECoG formats — with no conversion step, reads and writes the open NWB standard, and works alongside open-source tools like SpikeInterface and MNE.
Is there a free version of Radiens?
Yes — the Radiens Standard tier is free and permanent, and RadiensPy and the command-line tool are free at every tier; the paid Pro tier adds professional analysis, and lab-wide features are a Radiens Services conversation.
