How to create the LCD interface to the PYBMS generator: 1) Create a directory for PYBMS stuff and within that create three directories, orig, src and bin. The bin directory is for operating system dependent code so create a bin for each system type you have using links. 2) Get the generic PYBMS generator package from the SLAC LCD web pages and install it in the orig directory. 3) Move the executable pythia* from the orig directory to the bin directory. If more than one bin directory go back and rerun the Makefiles in the orig directory and subdirectories and again move the pythia* executable. 4) Copy the following files from the orig directory to the src directory: go pythcom.f bmscom.f pysubs.f pypars.f ludat2.f ludat3.f ludatr.f wwhpcom.f 5) Copy the two files that came with this README in the lcdpybms.tar to the src directory. They are runpyb pybms-bat* 6) In the general LCD generator/detector simulation package from SLAC there are task files for each desired generator and detector configuration. In the task files for pybms you will need to change some directory names. Gen-Batfile: point it to the src directory. Generator-ini: point it to the src directory. Gen-Code-Version: point it to the top PYBMS directory. If you have problems or suggestions regarding this installation package contact grb@slac.stanford.edu (Gary Bower).
