GUI Implementation
Updated on 2013-04-01
As an example of GUI style Marcin suggested to use XPCSGUI - earlier implementation of similar application.
Three versions of GUI were implemented for this application. It was decided to use the GUIMainTB
layout, where:
- All input windows are integrated in one with tab-bar for switching and custom tool bar on the top
- Logger and File Browser windows are isolated
- All plots are isolated, although similar plots appear in the same windows.
h3 Plots for intensity in q-static bins
Intensity monitors
FEEGasDetEnergy, XCS-IPM-02, XCS-IPM-mono, XcsBeamline.1:Ipimb.4, and XcsBeamline.1:Ipimb.5
Reflective scattering geometry
Source code from Marcin: q_functions.txt
Code location
Everything resides in CorAna
package, which is included in LCLS offline releases beginning from ana-0.7.16
.
References to the specific algorithms can be found in Algorithms for Time Correlation Experiments.
Original data processing code from Marcin is described in Note on XCS code from Marcin.
Modules
In tables below we list modules from packages CorAna
and ImgAlgos
, which were developed for this project.
Notations:
- is done (at least it is assumed for now...)
- needs more work
- test or deprecated modules

Functional description
Updated on 2013-10-14
In this section modules are listed in functional order.
PSANA modules
Dark run pre-processing
Scaner
Runs in batch for the dark file to get preliminary information.
ImgAlgos.ImgTimeStampList
- counts number of events in the file
- makes file with time stamps
- evaluate time intervals between frames (for dark run)
Pedestals
Runs in batch for the dark file to get averaged pedestals.
ImgAlgos.PrincetonImageProducer
gets image from event as an ndarray
object
ImgAlgos.Tahometer
evaluates performance of the batch job
ImgAlgos.ImgAverage
produces files with averaged, rms-spread, and hot-pixel mask for images in a given range of events.
Data pre-processing
Scaner
Runs in batch for the data file to get preliminary information.
ImgAlgos.Tahometer
evaluates performance of the batch job, counts number of events in the data file
ImgAlgos.ImgTimeStampList
makes file with time stamps and time record counters for tau
ImgAlgos.IntensityMonitorsData
makes file with intensity monitor records
Average
Runs in batch for the data file to get averaged image
ImgAlgos.Tahometer
evaluates performance of the batch job
ImgAlgos.PrincetonImageProducer
gets image from event as an ndarray
object
ImgAlgos.ImgAverage
produces file with averaged and rms-spread for raw images in a given range of events
ImgAlgos::ImgMaskEvaluation
- module is configured to evaluate masks:
- saturated mask - pixel is considered as saturated if its amplitude exceeds the threshold at least once per run
- noise mask - pixel is considered as noisy if its amplitude exceeds the MEAN+5*RMS in 5% of events. The "noise" MEAN and RMS are evaluated for 8 (or less on the boarder) surrounding pixels. This mask is not used in current analysis.
Data processing
Split
ImgAlgos.Tahometer
for performance evaluation.
ImgAlgos.PrincetonImageProducer
ImgAlgos::ImgCalib
module is configured to:
- subtract pedestals obtained for dark run
- account for threshold (LLD) constant or in number of RMS
ImgAlgos.ImgIntMonCorr
image normalization on intensity monitors data
ImgAlgos.ImgVsTimeSplitInFiles
split image and save blocks for all events in separate files.
ImgAlgos.ImgIntForBins
evaluate intensity (averaged over bin pixels) in bins per event, bin numbers are defined by the map, results are saved in the file.
ImgAlgos.ImgAverage
produces file with averaged and rms-spread for images with subtracted pedestals and allied LLD in a given range of events
Process
Data processing is implemented in stand alone (non-psana) modules
ImgAlgos.CorAna.cpp
ImgAlgos.CorAnaInputParameters.cpp
ImgAlgos.CorAnaData.cpp
Merge
ImgAlgos.CorAna.cpp
ImgAlgos.CorAnaInputParameters.cpp
CorAnaMergeFiles.cpp
- saves binary file for float(32) with shape (Ntau,3,rows,cols), where 3 stands for <Ip>, <If>, and <Ip*If>
Can be acessed in python as

View Results GUI
Contains a set of control fields for presentation of results
Direct and reflected beam geometry is implemented in ViewResults.py
. Currently the switch between the direct and reflected beam geometry is used from tab status variable: cp.exp_setup_geom.value()
...
.
If the PV variable will be used, then the switch should be changed in ViewResults.get_q_map(sp)
...
module.

basic

of

the

project.
ConfigParameters.py
, ConfigParametersCorAna.py
, and GUIConfigParameters.py
provides convenient approach for maintenance of all configuration parameters.
Infrastructural modules Logger.py
and GUILogger.py
provides a generic approach to logging system.
Module ConfigFileGenerator.py
use current settings of configuration parameters and stub-file scripts from CorAna/data/scripts/
and generates the psana configuration files.
Module FileNameManager.py
is a single place which provides a dynamic file names for current version of the configuration parameters.
GlobalUtils.py
- global utilities for common operations.
BatchJob.py
- superclass for batch job submission.
BatchJobPedestals.py
- pre-processing for dark run files.
BatchJobData.py
- re-processing for data files.
BatchJobCorAna.py
- main data processing - calculation algorithm.
RecordsFromFiles.py
- class helps to access data in files.
Status of the project
- This project is in the stage of comparison of results between old Marcin's scripts and this application.
Comparison of results
Conditions
- dark run:
/reg/d/ana12/xcs/xcsi0112/xtc/e167-r0020-s00-c00.xtc
use all 75 events - data run:
/reg/d/ana12/xcs/xcsi0112/xtc/e167-r0015-s00-c00.xtc
use all 500 events - do not use any intensity monitor selection or correction
- do not use any mask including hot pixel, saturation, blemish, ROI, and restriction on the image size.
- use LLD as a constant ADU threshold = 20
- use a single q-phi static bin
- use a single q-phi dynamic bin
- q value is not an issue for current comparison, so geometry does not matter.
