SeongwookChoi/PACT_CSF: v1.0 — PACT-based CSF analysis and quantification

This release provides the MATLAB code used for the quantitative analysis in the manuscript "Photoacoustic computed tomography monitors cerebrospinal fluid dynamics and glymphatic function." The repository includes: • NNMF-based blind spectral unmixing for multispectral photoacoustic volumes • ROI-based quantification of spinal cord and cisterna magna signals using percentile-based metrics • Normalization and plotting scripts used to generate the published figures The code reproduces the data-processing and quantification pipeline used for Figures 1–3 of the manuscript. This release is intended to serve as the stable, citable version of the analysis code for archival via Zenodo. Subsequent development or extensions will be tracked in later releases.
