A more comprehensive AMI-2 confluence page

Procedure

  1. ssh -X (or -Y) username@psana, the -X or -Y option enables X11 forwarding for graphic. The difference is that -Y is not encrypted so it is a little faster. 
  2. source /cds/group/pcds/dist/pds/ami2-devel/setup_env_lcls1.sh
  3. Work with the data source in a new flow chart or saved chart with .fc extension
  4. NOTE: when learning, or developing new graphs it can be useful to slow AMI down to 1Hz, using the "-b" and "-f" options to do this.   "-b" is a "heartBeat" interval in milliseconds (using the timestamps of the events being read!) and controls how often the plots update.  "-f interval=N" controls the interval (in seconds) between events read from disk.

Test Data and Examples

  1. ami-local -b 1 -f interval=0.01 psana://exp=cxilx9320,run=46,repeat=true &
    1. This is a dataset when we were aligning the gas cell
  2. ami-local -b 1 -f interval=0.01 psana://exp=cxilx9320,run=47,repeat=true &
    1. This is a dataset when we were aligning the pinhole 
  3. ami-local -b 1 -f interval=0.01 psana://exp=cxilx6520,run=244,repeat=true &
    1. This is a dataset of SF6 static scattering
  4. ami-local -b 1 -f interval=0.01 psana://exp=cxilx6520,run=214,repeat=true &
    1. No gas, X-ray background, we might have damaged the pinhole because the background looks bad...
