Todd, was it a particular dataset that resulted in the error? I tried the first 'item' on each 'page', and got a lovely plot returned ... 1) Precipitation -> Monthly precipitation rate GPCP ylo must be less than yhi (from the Java error messages)means that somehow the N latitude max value has been set to a value greater than the S lat bound. I've done this by mistake for regional datasets, those not having global coverage. Check the N/S bounding values in the UI Constraints page (88.75 for both is fine for all the datasets I looked at) It would be difficult to set these so ylo > yhi from a web client interacting with the UI constraints page, unless the ui xml config file has been set up incorrectly. check the server/log/debug contents for the y high and low values: ferret prop: y_lo = -88.75 ... ferret prop: y_hi = 88.75 and check whether ylo is lower (i.e. less) than yhi or check the Constraints page source to see how they've really been set: <input type="hidden" name="y_lo" value="-88.75" > <input type="hidden" name="y_hi" value="88.75" >Try putting the commands from the server/log/debug file in ferret and use the shade command to look at a variable from the dataset? Does that work?
