Preprocessing Guide

Brief guide to use preprocessing tools.

We assume that you already got the source code and runscripts. For each tool, source code, html documentation and runscript are under the same subdirectory. Each runscript will compile corresponding source code and run the executable to produce output data sets.

Steps to produce desired data sets

Find the directory of the tool which you want to use from tool directory table.
Read the documentation of the runscript at the head of each runscript
Modify the runscript to be compatible with your machine and compiler.
Read the html documentation of the source code to understand the namelist variable.
Configure the namelist option to obtain desired datasets.
Run it.
