Hi Ludovic, Thanks for your persistence in reporting what appears to be a bug. I have duplicated the problem here. Ed, the netCDF-4 developer, is away from the office until next week, but I'll see if I can figure out where the problem is. This is a major advertised feature of netCDF-4, so making it work correctly is a high priority! --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: NJG-578265 Department: Support netCDF Priority: Normal Status: Closed
