Hi Jonathan, > I have compiled netcdf4 with hdf5-1.8.2 and zlib-1.2.3. > When linking the math library, the file that I have attached > (qfed2.emiss.bc.005.20060505.nc) was unable to open with ncdump. I just tried an ncdump compiled with the current netCDF-4 version 4.1.1 on your file, and it seems to work fine, with no errors reported. However, I got the same error message you did, "NetCDF: Unknown file format", when using ncdump from netCDF versions 4.0 or 4.0.1. This is puzzling, because the only bug I'm aware of with netCDF-4 compatibility is with files written with a variable with more than 8 attributes on a big-endian platform using a version of HDF5 prior to 1.8.4-patch1. Your file has no such variable, so it should be readable. However, you can certainly work around the problem by installing the current release, using HDF5 1.8.4-patch1 or later for the underlying HDF library. In the meantime, we'll investigate further to see why that netCDF file is not readable with earlier versions of netCDF. Thanks for reporting this problem. --Russ > -----Original Message----- > From: Unidata netCDF Support [mailto:address@hidden > Sent: Thursday, August 26, 2010 12:41 PM > To: SMITH, JONATHAN WYNN.
