Yes NITRC Anticorrelated Component Analysis MATLAB MATLAB code to compute the two most anticorrelated patterns in a multivariate dataset. This technique was first applied to identify competing neuronal networks from the spontaneous activity of brain neural circuits in: Nathan X. Kodama, Tianyi Feng, James Ullett, Hillel J. Chiel, Siddharth S. Sivakumar, and Roberto F. Galán (2018). Anti-correlated cortical networks arise from spontaneous neuronal dynamics at slow timescales.
