I have added a get_posterior_covariance function to the image recon object. There is now an additional parameter passed to create an image recon object - lambda_R. I have checked the outputs on the ball squeezing dataset and the images and timeseries match exactly without spatial basis functions. The magnitude images should be unchanged from all prior results but t-statistics are updated due to the update to posterior covariance. I am getting some differences in the output with spatial bases for both magnitude and t-stat so I am still working on debugging that issue.
