At UMN, the odb information about each run is saved in the livedata directory which can be retrieved when needed. This information is not available in the cdmsbats processed datasets (root files). Goto to the folder,

  /data/chocula/k100/midasraw/livedata/

and look for the particular run number.

I have selected a particular dataset from Run 76 and opened in BatViewer to identify the run number associated with that dataset.

The file is: /data/chocula/k100/midasraw/byseries/07221027_0959/07221027_0959_F0001.mid.gz

My ODB file settings to look for is 47907.

Lets compare it with a file from Run 79.
