DAQ / Replay controls¶
The effects of the buttons depend on the current mode - DAQ or replay - and the current state of the system:
Action | DAQ mode | Replay mode |
---|---|---|
Start |
|
Start replay from beginning of file |
Stop |
|
Stop and rewind to beginning of file |
Pause |
|
Pause replay |
1 Cycle / Next Event |
|
|
The Start and 1 Cycle / Next Event buttons allow to choose what should happen with existing histogram data. Selecting Clear will clear all histograms in the current analysis before accumulating new data. Using Keep allows to accumulate the data from multiple replays or DAQ runs into the same histograms.
The Reconnect button will attempt to reconnect to the current VME controller. This is needed when using the VM-USB controller and power-cycling the VME crate as USB disconnects are currently not detected.
If Write Listfile is checked a new output listfile will be created when starting a DAQ run. The file will be created in the listfiles subdirectory of the current workspace. The filename is based off the current timestamp to make it unique.
If Write to ZIP is checked a ZIP archive with optional compression will be created instead of a flat .mvmelst file.
Replaying from listfile¶
To replay data from a listfile use File -> Open listfile and choose a .zip or .mvmelst file.
When opening a listfile the VME config included inside the file is loaded and will replace the current config. The global mode will be switched to Listfile. To go back to DAQ mode use File -> Close Listfile.
