Greg, I meant to mention one other development that is needed for dealing with chunk sizes. I'm adding an option to ncdump, which should be ready in the snapshot next week, that will display the chunk sizes for each variable in a file (as well as compression level and a few other per-variable settings). I'll let you know when it's available. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: VCQ-846449 Department: Support netCDF Priority: Normal Status: Closed
