PPI_correlation_demo

This script is to show the correlations between PPI terms (psychophysiological interaction) cauclated from two methods. One with deconvolution and the other without deconvoution. We show that the PPI correlations is a function task design frequency. This script has been used to generate Figure 1 in our paper titled "Psychophysiological Interactions in a Visual Checkerboard Task: Reproducibility, Reliability, and the Effects of Deconvolution".
