h1. DAQ how to 

on clrlpc, a-compton account

to start coda ( need to be in tcsh )

tcsh

startcoda

several windows will open

click in Control in rcgui pull down connect

select Configuration if not on desired configuration 

Hit config , download, prestart and go to start a run

Intelvmeha8 FADC only ( most stable )

FADCTDCDSC : FADC + F1 TDC + readout of discriminator scalers - need to reset and download at each run for now - still need to check 

In case ROC or PEB crash, do Ctrl-C in their window and do reset and rcgui and restart a run

To look at data :

on clrlpc :

type tcsh

cd companaEcal 

./compana

type run number

type a

type 1 for all events

Open root file in Rootfiles directory

root Rootfiles/vtpCerenkov_795.root

One liner to display all waveforms :

T->Draw("fadc_slot7:Iteration$","")

Look  at one fadc channel

T->Draw("fadc_slot7[3]:Iteration$","")

To display event by event :

i=0

T->Draw("fadc_slot7:Iteration$","Iteration$>200&&Iteration$<600","L",1,i++)

if you go up in history and hit enter it will display next event

Rough amplitude spectrum, you can use Sum$ in ROOT

T->Draw("Sum$(fadc_slot7[3])") 

will plot sum of all samples

You could eyeball the pedestal and window is 100 samples now

T->Draw("Sum$(fadc_slot7[3])-100*pedestal") 

would be centered at 0
