hi all, i'm trying to start using VisAD via the gentle route of using the spreadsheet to display some netCDF files (produced by someone else in my project). as i understand her output, it's basically x,y,z,t with a dimensionless number called "fraction" as the result. visad opens the file and even steps through the time series, but throws the following error message and displays nothing inside the wireframe cube: Couldn't decode attribute snof:units="fraction": Unit not in database other than asking her to assign a fake unit to it (e.g., "just say it's temperature in degrees Rankine!"), do you know offhand how to get visad to like such an input? thanks, -- rw "By filing this 'Bug Report' you have challenged the honor of my family.
