Subject: java.io.IOException: -101: NetCDF: HDF error
To: netcdf-java@xxxxxxxxxxxxxxxx
This is the exception am getting while creating Structure type of variable.
Please help me in this,
NetCDF-4 C library loaded (jna_path='null', libname='netcdf').
Netcdf nc_inq_libvers='4.3.2 of Feb 27 2015 14:08:46 $' isProtected=false

One more question , ToolsUI gives gray scale image , is there any
possibility of getting colored image??
Am using netcdf - java 4.5.4 and tried with 4.6.0
and i have installed netcdf -c 4.3.2.
Thanking you,
Raghav
