Hi Rory, > It appears that the -bf and -bc options to ncdump do not work in NetCDF > 4.3.0. Is this a know problem? Is there a patch or workaround? I didn't know about it until you and another user reported it yesterday. I've created a Jira issue for it and will try to fix it before the next release: https://bugtracking.unidata.ucar.edu/browse/NCF-275 --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: LEF-525393 Department: Support netCDF Priority: Normal Status: Closed
