1) Extract the Perple_X programs and data files in: www.perplex.ethz.ch/perplex/ibm_and_mac_archives/windows/Perp07_windows.zip www.perplex.ethz.ch/perplex/ibm_and_mac_archives/Perp_datafiles.zip to a single directory. 2) For information on some aspects of configuring your system to run Perple_X see: www.perplex.ethz.ch/faq/running_from_a_windows_console.txt www.perplex.ethz.ch/faq/Increase_page_file_size_in_windows.txt www.perplex.ethz.ch/faq/viewing_file_types_in_windows.txt 3) If you have no idea what Perple_X does or how to run it, then the tutorial at: serc.carleton.edu/NAGTWorkshops/petrology/teaching_examples/44110.html may be helpful (as this tutorial was written for Mac OSX users, Windows users must do a bit of lateral thinking to use it). If your interest is in the calculation of physicochemical properties, then following the worked problem at: www.perplex.ethz.ch/perplex07_seismic_velocity.html is the fastest route to getting results. A complete list of Perple_X documentation, such as it is, is at: www.perplex.ethz.ch/perplex_documentation.html 4) To use MATLAB to process Perple_X ouput see: www.perplex.ethz.ch/perplex/ibm_and_mac_archives/README_MATLAB_PLOT.txt 5) The Windows version of Perple_X was compiled on a machine runnning Windows XP with maximum optimizations. If you wish to compile your own version of Perple_X refer to the notes at: www.perplex.ethz.ch/perplex/ibm_and_mac_archives/README_UNIX_USERS.txt
