I've been trying to understand and/or fix a problem where occasional "HDF Error" is reported on reads from netcdf files.
It would be quite helpful if you would include the HDF eror -- it's probably two screenfuls of nonsense but it might give an indication of what went wrong.
==rob The errors are sporadic (but
reproducible) and necessitate a lot of "try/catch" type of structures to deal with the few values that are apparently corrupt. I've got to read terabytes of many small netcdf files and performance has been a problem in matlab, so I'm switching to fortran and hoping I can find out what the problem is and fix the netcdf, if possible. There is an old thread, referenced in my subject line, which mentions a function nf_set_log_level but this symbol seems to be missing from my netcdf library. Since it is undocumented, I wonder if anyone here can help.

If not for this, I would downgrade to netcdf 3. -Ed -- View this message in context: http://netcdf-group.1586084.n2.nabble.com/HDF-error-and-now-what-tp7575504.html Sent from the NetCDF Group mailing list archive at Nabble.com. _______________________________________________ netcdfgroup mailing list netcdfgroup@xxxxxxxxxxxxxxxx For list information or to unsubscribe, visit: http://www.unidata.ucar.edu/mailing_lists/
