Overview

The generation of Reduced Data Sets (RDS data) is managed by the driver scripts createrds.tcl and createrdsGUI.tcl.  These scripts use the LIGOtools ldasjob and dataflow packages to run LDAS getFrameCache jobs to update the list of time intervals to run on and LDAS createRDS jobs to reduce the data.  The scripts run under tclshexe and wishexe (also available from LIGOtools).

How to get driver scripts and documentation

• The createrds.tcl and createrdsGUI.tcl scripts are part of the dsorun module in the lscsoft cvs repository.
• See http://www.lsc-group.phys.uwm.edu/daswg/docs/howto/lscsoft-cvs.html for instruction on how to check out a module
• To set up dsorun on a reference machine, see http://www.lsc-group.phys.uwm.edu/daswg/projects/online/reference-server-machines.html
  
• To just get the driver scripts and supporting files:
• Set your CVSROOT environment variable:
• From bash or csh type shells respectively:  

• Login to the CVS archive:

• Check out the module

• For documentation:
• Check the sofware out of cvs and look at dsorun/contrib/createrds/scripts/README.createrdsAndcreaterdsGUI
• Or get this file from the web directly: http://www.lsc-group.phys.uwm.edu/cgi-bin/cvs/viewcvs.cgi/dsorun/contrib/createrds/scripts/README.createrdsAndcreaterdsGUI?cvsroot=lscsoft

Dependencies

To use the createrds.tcl and createrdsGUI.tcl scripts the following are required:

• The data that you want reduced must be visible to a running LDAS system.  
• See http://www.lsc-group.phys.uwm.edu/daswg/projects/ldas.html
• The LIGOtools ldasjob and dataflow packages must be installed, along with tclshexe and wishexe.
• See http://www.lsc-group.phys.uwm.edu/daswg/projects/ligotools.html
• The scripts must run as a user with a valid LDAS password installed in the user's .ldaspw file using the LIGOtools ldasjobs package.
• See the above web sites.
