Data Files from NDOS

This wiki entry describes how to collect data from NDOS and store it as a data file that can be used with our DDT framework.

First, you need to make sure that data is being collected! Once that is verified you can log into one of the NDOS buffer nodes:

ssh novadaq@novadaq-ctrl-farm-01.fnal.gov

NDOS has 16 buffer nodes (01 - 16). Note that the novaddt user does not have permissions on the buffer nodes.

Now you just need to set up the environment and run the job:

setup_novaddt
nova -c ddt-writeFile.fcl -o test.root -n 1

This will run over one event and create a file called test.root.
