About

This page provides examples for selected modules from Psana Module Catalog.

Auxiliary scripts

A few python scripts in ImgPixSpectra/data/ show how to process/plot the spectral array stored in the file.

PlotSpectralArrayFromFile.py - allows to plot content of the spectral array as a 2-d plot.
SpectralArray.py - provides access to the spectral array stored in the file. The class SpectralArray defined in this script is used in the PlotSpectralArrayFromFile.py.

MergeArrays.py - sums the arrays from different files defined in the list and saves resulting array in a single file with the same shape. In this script the list of files is hardwired in the get_list_of_input_file_names() method. The output file name, out_fname, is also hardwired in the call to spectra_merging(out_fname).

A few auxiliary scripts for example are located in the directory ImgAlgos/data:

psana.cfg - set non-default parameters to run psana for ImgAlgos::ImgPeakFinder and ImgAlgos::ImgPeakFilter
The psana running this script saves images and peaks for event 115 in text files.
PlotCameraImageFromFile.py - Plots image and spectrum for image saved in file.
PlotCameraImageAndPeaks.py - Plots image with found peaks and spectrum.

where module cspad_mod.CsPadCalib subtracts pedestals, apply common mode correction, and save CSPAD array in the event store with key "calibrated", which is used in the next module ImgPixSpectra.CSPadPixSpectra.

To run this script use command

psana -c psana-cxib2313-r0114-cspad-pix-spectra.cfg

which produces two files:

cspad_spectral_array.txt – array of 10-bin amplitude spectra for all pixels

cspad_spectral_array.txt.sha– file with metadata for array shape:

NPIXELS  2296960
NBINS    10
AMIN     -20
AMAX     20
NEVENTS  100
ARRFNAME cspad_spectral_array.txt

This algorithm consumes ~15 ms/event on psana0101 for full Opal1000 (1024x1024) camera image.
Smearing algorithm use a "safety margin" which is currently set to 10 pixels (offset from each boarder of the full image size).
Image on different stages of this algorithm:
raw image,
image in the window with amplitudes above the threshold_low
- few peaks at the edges were discarded by the window limits,
- image still contains many 1-photon pixels, which need to be eliminated,
smeared image,
raw image with found peaks (marked by the red circles)
zoom of the previous plot.

The file with the background array, bkgd_fname, was obtained by averaging 1000 events using module CSPadArrAverage. Subtraction is done with normalization for norm_sector=0.
Event image and pixel amplitude spectrum before and after the background subtraction are shown in plots:
Other event with better subtracted background:

See Module ImgAlgos::CSPadMaskApply
The array for mask contains zeros and ones for masked and passed pixels, respectively, and has a shape of full-size CSPad array 4*8*185 388.
For example, it can be generated by the command

./MakePixelMask.py <input-background-cspad-arr-file-name> <threshold> <output-file-name>

for the averaged background amplitude array <input-background-cspad-arr-file-name> abtained as a result of ImgAlgos::CSPadArrAverage module.
Plots show the averaged background, and the mask arrays generated from this background for three thresholds 10, 20, and 30 EDU:
The best results in filtering can be achieved in combination of modiles:

where
cspad_mod.CsPadCalib - subtracts the pedestals from raw CSPad data,
ImgAlgos.CSPadBkgdSubtract - subtracts the background,
ImgAlgos.CSPadMaskApply - apply the mask.
In the test with images for background represented by the water and solvent rings this filter provides the background suppression factor about 100.
The background images that still pass this filter have significantly larger intensity with respect to averaged background:
Input parameter mask_control_bits allows to control masking regions of 2x1. For example, if all edges need to be masked, then use mask_control_bits = 15, which gives image array like:
where red regions/lines of pixels of amplitude=8 are masked.

Example for TimeStampFilter and XtcOutputModule
This example demonstrates how to run psana with the time stamp filter and event writer in xtc file.
Both modules are available in psana library and they need only to be described in the configuration file. For example, the configuration file tstamp-filter-and-event-writer.cfg may looks like:

print_bits    = 11

Command to run psana is:
psana -c ./tstamp-filter-and-event-writer.cfg
For this configuration file psana will skip 10 events and loop over the next 100 events from the /reg/d/psdm/<INSTRUMENT>/<experiment>/xtc/e158-r0021-s0*-c00.xtc files and run consecutively modules = ImgAlgos.TimeStampFilter PSXtcOutput.XtcOutputModule. Parameters of these modules are described in the bottom part of the configuration file. Module TimeStampFilter passes events from the specified time interval and prints some useful information. Module XtcOutputModule will write passed events in the file with auto-generated name ./test_out/e158-r0021.xtcf.

Examples for Package py_img_algos
Package py_img_algos contains python modules which work with both frameworks pyana and psana.
Configuration file for pyana and/or psana should have relevant sections with parameters for [pyana] and/or [psana]. Alean section is ignored in each framework at run time. This is the only difference between two frameworks in the configuration file. All module descriptions are the same for two frameworks, as shown in examples below.
