Filter and inspect a recording

This takes a recording from raw to a processed file.

1. Open it. File → Open file… or Open folder… (SpikeGLX, raw .bin + .meta, NWB Zarr and more). The first open of a long file builds its pyramid in the background; you can scroll meanwhile.
2. Find what you need. In Explore, zoom out with Ctrl+wheel, and use a heatmap to see all channels. Double-click it to bring a channel up as traces.
3. Clean it. Click the view, then in the Inspector use Add op under processing. A common start for extracellular data is Filter → IIR → Spikes · band-pass 300–6000 Hz, then Reference → CMR.
4. Compare. Turn an op off to see the signal without it.
5. Keep it. In the Inspector, Write processed recording saves the chain to a float32 Zarr file, with its spec beside it, so the file says how it was made.

Run the same thing outside the app

The operations of a view are pipeline spec nodes. So what you tuned here also runs from dspk run or dspk.pipeline.run, on a whole folder of recordings.

See the graph

Open the Pipeline workspace: your view is a chain on the canvas. From here you can branch it, write several outputs, or make the chain a recipe.
