This directory contains the source code described in the paper: "Open Source Software in the Development and Testing of an Image-Guided Robot System" submitted to the Insight Journal for the ISC/NA-MIC Workshop on Open Science at MICCAI 2006 and available at http://hdl.handle.net/1926/227. The software requires the cisst library, Version 0.3.0 or higher, available at www.cisst.org/cisst. Additional software may be necessary depending on which modules are compiled. The CMake cross-platform build tool (www.cmake.org) is used. Following are the contents of this directory: CMakeLists.txt: the input file for CMake apps\Accuracy: source code for the Accuracy and Distances programs used for data analysis SW requirements: cisst (www.cisst.org/cisst), Accuracy program also requires a netlib binary (from www.cisst.org/cisst) data\June23-2005: the raw data files that were analyzed to obtain the results, and a batch file (RunAll.bat) to generate all results. libs\galil: the Galil motion controller library SW requirements: files must be downloaded from www.galilmc.com. libs\mskcc: the mskccRobot library (mskccRobot.h, mskccRobot.cpp), including Python wrapping. SW requirements: cisst (www.cisst.org/cisst), Swig (www.swig.org), Python (www.python.org), Galil library (www.galilmc.com) scripts: Python script files used for data collection The software has been compiled and tested in the Microsoft Windows environment, with the Microsoft Visual Studio.NET 2003 compiler.
