Parameters are: include_vars.
hdftotdf imports HDF or netCDF formatted datasets to TeraScan datasets (see datasets). HDF (Hierarchical Data Format) was developed by the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign. netCDF (network Common Data Format) was developed by Unidata Programs at the University Corporation for Atmospheric Research. Both of these dataset formats are public domain analogs to the TeraScan dataset format (see datasets). Each has independently produced a library of functions, and in some cases utility programs, to read, write, and manipulate multi-dimension, multi-type, multi-variable datasets. HDF has several interfaces built around 8- or 24-bit images, scientific data, tabulated data, etc. hdftotdf only imports the Scientific Data Set (SDS) format of HDF. As of version 3.3r3 of HDF, the HDF library views netCDF and SDS datasets synonymously. Thus hdftotdf can be used to import both HDF SDS datasets and netCDF datasets, with some caveats regarding backward compatibility (see documentation listed under NOTES).
Input datasets can be any valid HDF/SDS or netCDF datasets. One output TeraScan dataset is created for each input dataset. The input and output dataset variables have the same size data representation (e.g. , all 8-bit types are imported to GP_BYTE, all 16-bit types are imported to GP_SHORT, etc). All variable and global attribute information is imported as well as dimension names and scales.
Specifies the list of variables to import. Variable names must be specified exactly, and cannot be longer than 31 characters. Wildcards cannot be used.
The default is to export all variables.
