<html> <head> <style> .hmmessage P { margin:0px; padding:0px } body.hmmessage { font-size: 10pt; font-family:Verdana } </style> </head> <body class='hmmessage'> Patrick, I'm currently using MATLAB to modify input files, run simulations, and extract the results.  Here's an example command for running the simulation in MATLAB: dos('C:\HOT3000ReleaseCandidate2\bps -file C:\HOT3000ReleaseCandidate2\user\WizardHouse\cfg\WizardHouse.cfg -mode text -p def silent'); Where dos is the MATLAB command to run a program from the command line, the first term is the location of bps, the second in the cfg location, and def is the result set name.  That was used to simulate an ESP-r model made in HOT3000, but it would be the same for models made directly in ESP-r.  I don't think there's any need to modify ESP-r code.  The hardest part is figuring out some of the input file structures.  But you can deduce what things mean by using prj at first to modify one thing at a time and see how the input files change.  Of course, you could look at the ESP-r code directly to see how the input files are interpreted, but I didn't find this necessary. The results can be extracted fairly easily from the CSV or XML output files. Hope that helps.

Ideally, we want a way of getting teh data into esp-r, running the simulation, and the getting teh data out again, all without any file writing. Are there any api's that might simplify this task - I realise the software is open source, but delving into the core code is quite daunting. I am wondering if anyone has created a higher level api. If not, then maybe someone could point us to the righ place to start looking at the esp-r code.
