To run DQM

example uses run 7373  , and reads the files from cache (replace with the number of the run you are using):

1. Check to make sure that the evio files have been copied from the counting house to /cache/mss/hallb/hps/data/ before proceeding.  (Note:  the script hps2tape.sh, which copies the files to tape, also copies it to cache as well).  
2. Check if the DQM workflow already exists for the run before starting the DQM.  If it already exists, do not proceed.  In this case, DQM is either running, or is on queue to run on the farm.     
   •    swif status run-7373-dqm-workflow

3. Execute the following commands to create the workflow and run it.  
   
   

   •    ssh hps@ifarm
   •    cd /group/hps/production/dqm/scripts
   •    python mkworkflow.py 7373 --request --cache

A note from the DQM coordinator:   The mkworkflow.py script generates an error message if anyone attempts to execute it from any account other than the hps account.  This is intentional, because whichever account starts the workflow owns the dqm files, which only the hps account should own, not somebody's personal account (including the DQM coodinator).
