This page provides a list of existing modules for psana framework. Only the modules that are included in the standard analysis releases appear on this page.

Package psana

Psana package include several simple modules which do generic tasks that do not need knowledge of the event data types.

Module psana.EventKeys

This module dumps the list of the event keys in the event or configuration store. Event key is a triplet of data type, data source address, and string key.

Example of the output produced by this module:

Event keys:
  EventKey(type=Psana::EvrData::DataV3, src=DetInfo(NoDetector.0:Evr.0))
  EventKey(type=Psana::Camera::FrameV1, src=DetInfo(CxiDg1.0:Tm6740.0))
  EventKey(type=Psana::Ipimb::DataV1, src=DetInfo(CxiDg1.0:Ipimb.0))
...

This module is useful to display the content of the events without dumping all the data. Example command which uses this module is:

% psana -m EventKeys <input-files>

Note that one can specify EventKeys instead of psana.EventKeys as psana package name is optional.

Module psana.PrintEventId

This module prints the content of the Event ID object on every event.

Example of the output produced by this module:

[info:psana.PrintEventId] event ID: XtcEventId(run=100, time=2010-12-12 11:09:36.300506429-08)
[info:psana.PrintEventId] event ID: XtcEventId(run=100, time=2010-12-12 11:09:36.317163082-08)

Module psana.PrintSeparator

This module prints separator line on every event. Can be used to indicate event boundaries in job's log.

Module has two configuration parameters:

  • separator (default: "=") – separator string
  • repeat (default: 80) – number of repeats of separator string on a separator line

Example of the output produced by this module with the default parameters (including output from PrintEventId module):

[info:/root/] ================================================================================
[info:psana.PrintEventId] event ID: XtcEventId(run=100, time=2010-12-12 11:09:36.300506429-08)
[info:/root/] ================================================================================
[info:psana.PrintEventId] event ID: XtcEventId(run=100, time=2010-12-12 11:09:36.317163082-08)

Package CSPadPixCoords

Package CSPadPixCoords calculates the 2x1 section, quad, and CSPad pixel coordinates and produces the image.
For complete reference select Doxygen documentation.

Module CSPadPixCoords::PixCoordsTest

This module demonstrates of how to use the PixCoords2x1, PixCoordsQuad, and PixCoordsCSPad classes
in order to pre-calculate pixel coordinates, taking into account the calibration parameters.
Relevant images are produced in combination of the pixel coordinates with event data and saved in text files.

Module configuration parameters:

  • calibDir (default: "/reg/d/psdm/CXI/cxi35711/calib") – directory with calibration files,
  • typeGroupName (default: "CsPad::CalibV1") – data type and group names,
  • source (default: "CxiDs1.0:Cspad.0") – source of data,
  • runNumber (default: 32U) – run number for calibration file,
  • events (default: 32U) – number of events before stop a job,
  • filter (default: false) – on/off for potential selection filter.

Module CSPadPixCoords::CSPadImageProducer

CSPadImageProducer works in psana framework. It does a few operation as follows:

  • gets the pixel coordinates from PixCoords2x1, PixCoordsQuad, and PixCoordsCSPad classes,
  • gets data from the event,
  • produces the Image2D object with CSPad image for each event,
  • adds the Image2D object in the event for further modules.
    Time consumed to fill the CSPad image array (currently 17501750) is measured to be about 40 msec/event on psana0105.

Module configuration parameters:

  • calibDir (default: "/reg/d/psdm/CXI/cxi35711/calib") – directory with calibration files,
  • typeGroupName (default: "CsPad::CalibV1") – data type and group names,
  • source (default: "CxiDs1.0:Cspad.0") – source of data,
  • runNumber (default: 32U) – run number for calibration file,
  • events (default: 32U) – number of events before stop a job,
  • filter (default: false) – on/off for potential selection filter,
  • tiltIsApplied (default: true) – on/off for tilt angle of 2x1-sections and quads.

Module CSPadPixCoords::CSPadInterpolImageProducer

CSPadImageProducer works in psana framework. It does a few operation as follows:

  • gets the pixel coordinates from PixCoords2x1, PixCoordsQuad, and PixCoordsCSPad classes,
  • makes the arrays of neighbour addresses (quad, section, row, column) and weights as a function of the bin indexes (ix, iy) of the CSPad image.
  • gets data from the event,
  • produces the Image2D object with interpolated CSPad image for each event,
  • adds the Image2D object in the event for further modules.
    Time consumed to fill the CSPad image array (currently 1750x1750) is measured to be about 200 msec/event on psana0106. We consider options for acceleration using GPU or multi-core processing.

Module configuration parameters are the same as for the CSPadPixCoords::CSPadImageProducer.

Module CSPadPixCoords::CSPadImageGetTest

CSPadImageGetTest is a psana module class, which works after CSPadImageProducer. It gets the Image2D object from the event. This image object may be used in data processing. For the test purpose, the image of particular event is saved in the text file. This event number is defined in the psana.cfg configuration file.

Module configuration parameters:

  • source (default: "CxiDs1.0:Cspad.0") – source of data,
  • events (default: 10000000) – number of events before stop a job,
  • eventSave (default: 32U) – event number to save the CSPad image file,
  • filter (default: false) – on/off for potential selection filter.
  • No labels
