How to install PEST


How to install PEST

PEST is an advanced software tool for
model calibration, parameter estimation and predictive uncertainty
analysis. It is open-source and freely available, and currently distributed
by S. S. Papadopoulos &
Associates, Inc.
The Simile interface has been verified
to work with PEST version 9 and later, on Windows, Linux and MacOS.

Windows users can download a
pre-compiled version of PEST from this site and follow the instructions to
enable it to run from the command line. Typing 'pest' to the command prompt
will produce a message about usage if it is correctly installed.

Linux and Mac users will need to
compile PEST from source. PEST is written in FORTRAN, and the GNU g95
compiler is suitable for compiling it. This is part of the GNU compiler
collection, and is freely available from SourceForge.

It should be possible to build
the package using the makefile shipped with it. The simplest way to get
this to work is to create a symlink called 'f90' to the g95 compiler, since
the makefiles all include f90 as the default compiler name. This can be
placed in a directory in the executable search path, e.g., ~/bin. A symlink
to the PEST executable can also be made in this directory once it is
compiled.

Check that PEST is installed
correctly by typing 'pest' to the command prompt before attempting to run
it from within Simile. If it is set up correctly, it will generate a usage
help message.
