Delay Differential Analysis Laboratory
Nonlinear time-series analysis for neurophysiology research. Fit delay differential equation models to sliding windows and reveal dynamical structure through Q-matrix coefficients.
This web demo runs the Single-Timeseries (ST) variant entirely in your browser using Web Workers. No data leaves your machine.
Web demo: CSV, TXT, TSV, EDF.
Desktop app: adds BrainVision, FIF, EEGLAB, XDF, NIfTI, and NWB.
The desktop app supports ST, CT, CD, DE, and SY variants with real-time streaming, preprocessing, and institutional collaboration.
The ST variant fits this third-order delay differential equation to each sliding window via least-squares, yielding coefficients c1, c2, c3 that characterize the local dynamics.
