Psana

  • Updated to handle new DAQ types: Evr::IOConfigV2 and Bld::BldDataSpectrometerV1
  • In GeometryObject add support for cspad2x2-shaffling of pixel arrays, both in C++ and Python
  • CalibManager

    • V00-00-65 - PlotImgSpeWidget.py - print image intensity along with coursor coordinates in coursor motion

       
    • V00-00-63 - in OpticAlignmentCspad*.py - add option parser for manual processing of metrology files
    • V00-00-64 - OpticAlignmentCspad* - add in all output geometry files the line with detector position relative to IP;  

      in ConfigParametersForApp, ConfigFileGenerator add support for Fccd960

  • PixCoordsProducer V00-03-64  
    • save geometry file name as a string (as ndarray<char,1> - is depricated but still available)
    • add saving mask for edge and unbound pixels 
    • add x,y origin offsets for indexing
  • CSPadPixCoords::CSPad2x2ImageProducer V00-03-28 - use the "geometry" calibration file if available
  • TimeTool: the TimeTool.Analyze module now uses TimeTool::ConfigV1 for defaults and outputs TimeTool::DataV1 when appropriate. The TimeTool::ConfigV1 data will be written when upcoming experiments use the online DAQ TimingTool. If the experiment did not use the DAQ timing tool, this data is not written. The TimeTool::DataV1 object will be more convenient to work with from Python and C++ than the ndarrays that one could output before.
  • DDL system (of interest to internal developers, not general users)
    • new tag for types: [[devel]] means by default do not generate code, it is in development (like skip)
    • Generating code for [[devel]] tagged types is enabled by adding -D switch to psddlc or GENDEVEL=1 when running make to build the 'gen' target in pdsdata

External Packages

  • pdsdata update to 8.1.5 with new DAQ type mentioned above, and new Bld Ipimb sources.

  • new external Python packages added:
    • pywt: PyWavelets - Discrete Wavelet Transform in Python
    • lmfit: Least-Squares Minimization with Bounds and Constraints

Tests

  • no new tests

Bugs fixed

  • CalibManager V00-00-62 - in OpticAlignmentCspad2x2V1.py fix segment rotation angles 0 -> 180
  • pypsalg: Fix bug in AngularIntegrationM where centers were not set correctly

Known Issues

  • Pyana does not support the new Bld Ipimb sources in pdsdata 8.1.5
  • Python applications using h5py with parallel HDF5 would hang when exiting. Apparently, there is a deadlock caused by either mpi4py or h5py implementations. We're looking at this problem.
  • h5py and hdf5 users may run into a bug in the hdf5 library 1.8.13. After many loads of a dataset (4194220 I believe), in h5py one can get the error RuntimeError: Unable to register datatype (Can't insert duplicate key). This will be fixed in hdf5 1.8.14 due in November. In the interim, if one can rewrite code to load the dataset less this should resolve it. We can also look into applying the patch to hdf 1.8.13 if need be.
