This implementation of Win32e GrADS has most of the functionality of all Unix versions. Supported features include:
|
|
|
|
Command line editing (readline) | X | X | (partial) |
NetCDF support | X | X | X |
HDF support | X | X | |
DODS support | X | X | |
LATS | X | X | X |
Athena Widget GUI | X | ||
Image Magick (wi command) | X | ||
Image printing (printim command) | X | X | X |
As can be seen, X/Win32 GrADS has all of the functionality found in the Unix versions of GrADS. However, it requires the installation of an X server. This version (Win32e GrADS) does not require an X server, but currently lacks Athena GUI and Image Magick support which may be required by some users. The MS-DOS version of GrADS is the least featured; however it has the fastest graphics and runs well on low end PCs (I've heard of users running it on ancient 386 boxes). The choice is yours. For GrADS download information, consult http://grads.iges.org/grads/downloads.html .
Note: The directory structure of the PC GrADS binaries is designed in such a way that all PC versions could be installed on the same machine, sharing the same dat/ (fonts and map datasets) and lib/ (script library) directories. The particular version of "grads" to be executed would depend on how you have your PATH set.
Application | Description |
Grads | Win32 GrADS with the classic command line interface (ga-> prompt). This version is the same as GradsNC below and can read and write NetCDF files (but no HDF-SDS files); see sdfopen , xdfopen . |
GradsC | Win32 GrADS with the classic command line interface (ga-> prompt), but without NetCDF/HDF-SDS, LATS, Athena GUI or Image support through the wi command. This version can read IEEE and GRIB files. This is the smallest version of Win32 GrADS and requires the least amount of memory. |
GradsHDF | Win32 GrADS built with NCSA's MFHDF (Multi-file HDF) library. With this configuration GrADS can read both NetCDF and HDF-SDS files (see sdfopen , xdfopen ), but can only write HDF-SDS files (but cannot write NetCDF files). IEEE and GRIB files are fully supported. |
GradsNC | Win32 GrADS built with Unidata's NetCDF library. With this configuration GrADS can read (see sdfopen , xdfopen ) and write NetCDF files, but cannot handle HDF-SDS files. IEEE and GRIB files are fully supported. |
Gv32 | Windows' based GrADS metafile viewer. |
Gxtran | Classic metafile viewer (Gv is nicer). |
Gxeps | Converts GrADS metafiles to enscapsulated postscript (faster). You may want to obtain the Windows version of Ghostview (gsview), freely available from http://www.cs.wisc.edu/~ghost/gsview/. Gsview will allow you to preview and print PostScript documents on win95/NT. Highly recommended. |
Gxps | Converts GrADS metafiles to postscript level 1 (slower) |
Gribmap | GRIB file mapping utility |
Gribscan | GRIB file scan utility |
Wgrib | Wes Ebisuzaki's GRIB utility (it slices, dices) |
Stnmap | Station mapping utility |
Ncdump | Convert NetCDF/NDF-SDS files to ASCII form (CDL). For source code and additional information consult http://www.unidata.ucar.edu/packages/netcdf . |
Ncgen | From a CDL file generate a netCDF file, a C program, or a Fortran program. For source code and additional information consult http://www.unidata.ucar.edu/packages/netcdf . |
HDFdump | Similar to Ncdump , but can read HDF-SDS files. Note: avoid using this utility for NetCDF files due to a bug related to packed NetCDF files. For source code and additional information consult http://hdf.ncsa.uiuc.edu. |
Hdfgen | Similar to Ncgen , but output is in HDF-SDS format.For source code and additional information consult http://hdf.ncsa.uiuc.edu. |
sh | Win32 port of the GNU Bourne Again Shell (bash). This utility is needed for executing shell commands from grads, e.g., ! ls. For documentation of GNU software consult http://www.gnu.org/doc/doc.html. For source code and additional information, consult http://www.cygnus.com/gnu-win32. |
rxvt
|
A nice terminal for replacing Windows COMMAND.COM. For running
it you may need to create the directory c:\cygwin\tmp .
Once started, you can start GrADS from it; the default is the Unix shell sh. |
ls, cp, rm. mv, pwd, cat | Assorted GNU file utilities to facilitate porting GrADS scripts from Unix to Win32. For documentation of GNU software consult http://www.gnu.org/doc/doc.html For source code and additional information, consult http://www.cygnus.com/gnu-win32. |
*.dll | These are Dynamic Link Libraries (DLL) needed by the applications above. If you move them to a different directory, make sure they remain in your PATH. The DLL files above are usually not visible from the Win32 GrADS Program Group. You can change this default behavior from the View/Properties menu of the Windows Explorer. |
You can also start Win32e GrADS or any of the applications above from the DOS command line, e.g.,
c:\> gradsRecall that DOS is case insensitive, so grads is the same as GrADS. You may want to put the GrADS binary directory (usually c:\progra~1\pcgrads\win32e ) on your path. You can optionally set the DISPLAY environment variable as explained above.

User's Guide | As of version 1.8, an on-line version of the GrADS User's Guide is available. For convenience a copy is also provided here, along with an alphabetical index. It is recommend that you consult the on-line version for up to date information. A tutorial is also available. |
cards/ | Quick reference cards for GrADS commands and GrADS scripting language
in PostScript, both in A4 and US Letter sizes:
You may want to obtain the Windows version of Ghostview (gsview), freely available from http://www.cs.wisc.edu/~ghost/gsview/. Gsview allows you to preview and print PostScript documents on win95/NT. Highly recommended. |
etc/ | Unix style manual pages/text documents for several utilities:
