Login to cernbook
go to /home/trd/SMComm/SM_Test_CERN_Ana/eventdisplay

% ln -s /home/trd/SMComm/SM_Test_CERN_Data/sm08_commission_May2007/digit/"TRD.Ditits.*.root you want to display" TRD.Ditits.root
% alieve
root [0] .x $ALICE_ROOT/EVE/alice-macros/init_trd.C
Then, in the Reve GUI, you click "Digits" and open a TRD.Digits.root file using "Open" button,
Select Event 0 for dcs readout cosmic data,
Select SM 8 at Chamber selector(-1 means all detectors), otherwise you will see some complaining message due to not existing SM reading,
Select Digits in the Data selector,
Then you will see displayed digits in the GL viewer. If you zoom in, you might see cosmic signals. :)
