To install the program: 1. Unpack the distribution files on the target directory: gzip -cd analyze.tar.gz | tar xf - 2. Change to appropriate source directory source_clust/Makefile_platform and/or source_nmr/Makefile_platform (where platform = AIX, SunOS, IRIX or IRIX64) and properly set your executable directory, as well as the compiler options (the ones provided should, however, be fine). 3. Run make to create the executable analyze-clust-platform.x and/or analyze-morass-platform.x. To get rid of the object files you can then run make clean. 4. Edit the script(s) ../bin/analyze-clust and/or analyze-morass and set the DBASDIR variable to the path to your ECEPP residue database directory and change the name of the database, if necessary. Alternatively, you may define the environment variable ANALYZE_ROOT as the full path to your analyze directory. Add path to analyze/bin to your $path variable. 5. Run the tests contained in the examples directory (you may want to use the script examples/runall.csh or run the specific tests one by one; each lowest-level directory contains the script run.csh which does this). See examples/README for details.
