Thanks. Your instructions were very clear and easy to follow. Unfortunately it did not seem to have any effect on the system. I still had to go through the long selection for streamlines and I did not get any derived parameters from RH and Temp.
Sorry that didn't work. I assume you went through the set of steps with the Alias editor?
If so, the Alias editor writes out an xml file in your local home directory: ~/.metapps/DefaultIdv/aliases.xml Could you send me that file and I can take a look at it? Also, is the data file that you are using available for me to load? -Jeff
