[gate-users] Counts vs. time slice

[Eva Nerina Gimenez Navarro]

Hi Dirk, 

Indeed I remove all lines related with time, as it was suggested in  
Groisselle - Foudray e.mail, i.e. the following lines: 

/gate/application/setTimeSlice     120  s
/gate/application/setTimeStart     0.  s
/gate/application/setTimeStop      120  s
/gate/application/startDAQ

I tried what you told me and I set again the first three commands. 
Now, it works! 
It seems that as I remove those lines, the program was working with a 
predefined time of 1 second. 

Thanks for your advice.
Best regards, 
Nerina
