Installation of hyperslab operators (IDL version)

To install the IDL version of the hyperslab operators on your machine, grab the compressed tar file hops1.6_idl.tar.gz, and untar it in the directory where you keep your IDL scripts. Untarring will create a directory hops, with several subdirectories. Make sure you use the "+" prefix with the EXPAND_PATH function in IDL to make it search all the subdirectories. (See the HOPS Reference Card)

Note 1: Mapped projections (such as polar stereographic) are handled through the contouring routine hops/prog/trishade.c, which may be compiled as a dynamical library using the C-shell script hops/prog/make_trishade.csh. The two calls to the IDL function CALL_EXTERNAL in hops/plot/fcont.pro must also be modified to properly load this dynamical library.

Note 2: EOF computations are done using an external Fortran program hops/prog/eofcompute.F. It should be compiled and linked with the public domain LINPAK library, and the executable should be named eofcompute0. The EOF operator hops/tops/tseof uses the C-shell script hops/bin/eofcompute to invoke the program eofcompute0. This script may need to be modified.

Note 3: To convert CCM3 history files to netCDF, you can use the ccm2nc utility.
