Hello, When I run featquery on a cope image from a block design study, I get time series data that looks like this: 12855.1 12788.5 12775.5 12696.3 12722.7 12678 12904.1 12788 12626.8 12779.7 12671.4 12874.4 13034.7 13095.4 etc. How can I convert these numbers to percent signal change? Thanks, Jodi
