Hi Ben, Which version of Java are you using (from the command line: java -version)? Also, McV is pretty much IDV with some additions, so if IDV runs, than McV should run. The reason I suggest McV is because it comes bundled with the ADDE server, which does the calculations on the raw files to convert them into things like IR brightness temperatures. When you access satellite data through the IDV satellite chooser, you connect to a remote ADDE server. Then, when you select a product to view, the ADDE server will do the necessary calculations before sending you the data to view. When reading the raw data off of disk, you need a local ADDE server to active the same functionality, which is why McV bundles the ADDE server. I think page two of this pdf explains how to do this in McV: http://www.ssec.wisc.edu/mcidas/software/v/docs/SatelliteImagery1.01.pdf Cheers!
