FLOUNDER - A software for WAXS image data processing


FLOUNDER is a basic software for the analysis of wide-angle X-ray scattering data at the Photon Factory. Detector(available): PILATUS(3) 100K, 200K, 300K & 300K-W (tif/cbf) (Dectris).


Main function

  1. Mask file making.
  2. Calibration of the beam center and the camera distance using a powder pattern (eg.Ag behenate).
  3. TIF and CBF format of PILATUS are available. Circular average (2D -> 1D).
  4. Data subtraction (Sample - Background).


Operation condition

Windows 10, 11 (64 bit only)

History

  • Ver 1.0.39 release. (2024/2/9)
  1. Improved file loading method and update interval during Autorun to accelerate the rendering speed of PointPickViewer.
  2. Enhanced input validation in the Autorun settings form on the Average tab.
  3. Modified the Autorun settings form on the Average tab to inherit the counter file number set in Average.
  4. Added the [Clear] button for the file list in PointPickViewer.
  5. Enhanced the 3D plot rendering function of PointPickViewer.
  6. Fixed several minor bugs.
  7. Japanese manual updated for Ver 1.0.39.
  • Ver 1.0.37 release. (2023/10/23)
  1. Default file names have been set for files output from the Point Pick viewer.
  • Ver 1.0.36 release. (2023/9/7)
  1. The definition formula for determining the normal or abnormal pixel values in the Uniformity correction function of image data in the Mask tab has been modified. It now allows for detection without being influenced by the data's Signal-to-Noise Ratio (S/N). The same function in the CirAve tab has also been similarly adjusted.
  2. Fixed several minor bugs.
  • Ver 1.0.35 release. (2023/7/10)
  1. Updated the Point Pick Viewer to allow loading data in formats other than FLOUNDER (assuming the scattering intensity data is in the second column). The supported delimiter characters are TAB, comma, and space.
  2. Modified the display of 2D image data loaded in the Mask and Calibration tabs to adjust the displaying area based on the detector model specified in the Detector tab.
  3. Fixed several minor bugs, including one related to transmittance calculations.
  • Ver 1.0.33 release. (2022/9/2)
  1. Fixed a bug related to the "Pixel pitch" in the Ave tab. This bug had been appeared when the "Pixel pitch" was set to a value other than the default of "1/1" in the Ave tab.
  • Ver 1.0.32 release. (2022/4/15)
  1. The mask drawing tool has been updated to make it easier to recognize the drawing area.
  2. The output format of negative values due to conversion to logarithms has been changed in AnalysisTool. These values were output as 0 previously, but they are output as "NAN" from this version.
  3. Japanese manual updated.
  • Ver 1.0.29 release. (2021/11/9)
  1. Improved GUI of PointPickViewer.
  2. Japanese manual updated.
  • Ver 1.0.28 release. (2021/6/19)
  1. Improved PointPickViewer to allow selection of the data display range.
  2. Fixed several minor bugs.
  3. Japanese manual updated.
  • Ver 1.0.27 release. (2021/5/12)
  1. At the first boot after installation, the number of parallel threads is automatically set to 1/2 the number of total logical processors in the PC.
  2. The image data displayed in Mask Drawing can be scaled down to a minimum of 10% in order to support the small screens of laptop computers.
  3. Adjusted the counter values to be displayed to the decimal point in the GUI (up to 9 digits).
  4. The Double type is used in all calculation processes, but in the output file (dat), the Ch value of the counter was partially omitted. The CH values recorded in the dat file were changed to be output in Double type from this version.
  5. Fixed several minor bugs.
  • Ver 1.0.22 release. (2021/3/3)
  1. Fixed a minor bug related to connecting to ATSAS.
  • Ver 1.0.20 release. (2020/11/6)
  1. The module name, "SAnglerAnalysis" is changed to "AnalysisTool".
  2. The value of "Mutch" at Calibration process is recorded in the header region of cal file.
  3. Several minor bugs were fixed.
  4. Japanese manual is available.
  • Ver 1.0.11 release. (2019/08/23)
  1. Analysis Tab was omitted from Tab lists. Analysis window (SAnglerAnalysis.exe) can be multiply booted from File menu, Analysis - SAnglerAnalysis.
  2. In order to exclude abnormal pixel data at the time of azmuthal average, a function ("uniformity") of creating histogram data of scattering intensities for each value of the X-axis is added in Mask tab. Users can update the mask file to exclude illegal pixels from the calculation based on the set threshold.
  3. Several bugs were fixed.
  • Ver 1.0.7 release. (2019/02/15)
  1. The software name changed from WAngler to FLOUNDER. Several bugs were fixed.
  • Ver 1.0.5 release. (2019/01/24)
  1. Several bugs were fixed.
  • Ver 1.0.3 release. (2018/10/03)
  1. The specification of the file (calibrant.xml) used for the calibration has been changed.Accordingly, the method to input the calibration data has also changed.
  2. Several bugs were fixed.
  • Ver 1.0.0 release. (2018/08/03)
  1. WAngler ver 1.0.0 was officially released.
  • This page and WAngler ver 0.0.12 were tentatively released. (2018/07/03)
