Glossary
Terms used across this documentation and inside the application. Anywhere one of these appears in the docs, hovering it shows the definition.
| appcast | The XML feed that update frameworks read to learn whether a newer version exists. |
| baseline | A span used as reference, subtracted from each trial so that changes are measured relative to a resting level. |
| BIDS | Brain Imaging Data Structure. A convention for laying out neuroimaging datasets so that tools can find things without being told. |
| bipolar | A reference scheme where each channel is the difference between two neighbouring contacts, which suppresses signal common to both. |
| canvas | The surface in the builder where cards are placed and wired together. |
| CAR | Common average reference. Each channel has the average across all channels subtracted from it. |
| card | A single processing step on the canvas. A folder with a manifest declaring its ports and parameters, and an implementation. |
| CCEP | Cortico-cortical evoked potential. The response recorded at one site when another is electrically stimulated. |
| epoch | A segment of the recording cut around an event, so trials can be compared. |
| FDR | False discovery rate. The expected proportion of false positives among the results called significant. |
| FIR | Finite impulse response. A filter whose output depends only on a finite window of input samples, which makes its phase behaviour predictable. |
| gears | The view that opens a single card and shows the operations inside it, with every value resolved. |
| iEEG | Intracranial electroencephalography. Recording from electrodes placed inside the skull. |
| manifest | The JSON file that declares what a card is: its ports, its parameters, and how it runs. |
| MNE | MNE-Python, the reference implementation used to validate cards. |
| montage | The arrangement of electrodes and how each channel is referenced. |
| Nyquist | Half the sampling rate. No frequency above it can be represented, so no filter can pass one. |
| port | A typed connection point on a card. Inputs accept data, outputs produce it. |
| sEEG | Stereoelectroencephalography. Intracranial recording from depth electrodes inserted along trajectories. |
| slug | The short identifier of a marketplace entry, used in its address. |
| SOZ | Seizure onset zone. The region where seizures are judged to begin. |
| taps | The number of coefficients in a FIR filter. More taps give a sharper transition and a longer delay. |
| workflow | A saved graph of connected cards. The file is the pipeline: opening it reproduces the analysis. |
