Hi Gang,

I had to increase my range to -2000 2000 before the covariance matrix game values that weren't hitting the boundary. But how would i now interpret this? Should I maybe consider going back and re-extracting the time series for my ROIs, perhaps leaving in the trend or scaling to 1 max 2?

I did try, also, to use the correlation matrix, and the final output matrix from 1dSEM seems interpretable. I've pasted it below. Would this seem reasonable. Thanks a lot for the help.
