The attachments appear to have been lost in transit. Can you post them inline (if not too large). Also, let me verify some things: 1. you are using the netcdf-c library (hidden by matlab). 2. Can you get your web browser to access the data through the proxy? If so, how do you tell your browser what proxy to use? 3. Does the proxy require a password itself? 4. How, if at all, are you telling matlab what the ip of the proxy to use? =Dennis Heimbigner Unidata Ticket Details =================== Ticket ID: NKA-280167 Department: Support netCDF Java Priority: Normal Status: Open =================== NOTE: All email exchanges with Unidata User Support are recorded in the Unidata inquiry tracking system and then made publicly available through the web.
