Hi Tom, I can open the file in ToolsUI both 4.0 and 2.2. I'm doing this from the "Veiwer" tab. Is that how you are opening the file? If I try the "Grids" tab, it doesn't get recognized as a gridded dataset in either 2.2 or 4.0. What version of ToolsUI 4.0 are you running? I tried both our webstart version (4.0.31.20090129.2311) and the latest from our code repository. Ethan > The subject says it all -- tried opening it in toolsUI-4.0 and IDV -- > no go.
