Latest Software "ASYURA.exe" (Mac)

Latest windows version (2024/02/01)

• I have released the ASYURA version for Mac. Please note that the Windows version is updated more frequently, so the Mac version may be slightly older.

Latest Software "ASYURA.exe" (windows)

windows version (2024/04/22)

1. I've resolved the issue with error bars. 

2. I've fixed the issue with selecting background data. 

3. I've changed the unit of input for the smoothing feature from % to rlu. 

4. Additionally, I've implemented the advance mode, which allows for 2D slices and 1D cuts in arbitrary axis directions. 

windows version (2024/04/04)

1. I have resolved the issue with TAS mode. 

2. The aspect ratio of graphs in constant energy cuts has been modified. 

3. Additionally, I have added the functionality to display grids in color plots.

windows version (2024/04/03)

1. I have made it so that when selecting a file, it adds to the previously selected files. If the same file is selected again, all but one instance will be excluded. 

2. The aspect ratio for constant E cut graphs has been modified to be normalized by Q. 

3. I have also changed the label of the slider for adjusting the maximum intensity value.

windows version (2024/03/01)

1. I have resolved the issue where processing was not done when there was only one data point in the dat file. 

windows version (2024/02/05)

1. I corrected an error in the calculation method for the intensity type, and adjusted it to the correct calculation method. 

2. I also modified the calculation to allow for the mutual computation of λ and E in the calculation module. However, it should be noted that the calculation of 2θ, Q, and d is still based on E. 

3. I added the capability to differentiate between hours and minutes in the time estimation for scanning. 

4. The help function has been enhanced.

windows version (2024/01/30)

1. I have implemented a smoothing function. Please input numerical values for δU, δV, and δQ. You can set it as a percentage of the bin size. Increasing the bin size by δU, δV, δQ(%) means widening the bins and summing the values. In other words, setting it to 100% will also add the intensity of the neighboring bins.

※While this function is powerful in improving the clarity of the figure, be cautious as it may result in double-counting data within the range specified by δU, δV, δQ(%). Please pay sufficient attention to this aspect.

2. I have changed the output format for data storage.

3. I have implemented the ability to estimate the time for scan simulations. 

4. For single crystal scan simulations, we have introduced sliders in the constant energy map to allow you to visualize the scan range.

5. I made some changes to the user interface (UI).

windows version (2024/01/16)

Significant update implemented. 

1. The UI has undergone considerable changes. It has been redesigned to enable almost all functions to be performed on a single screen. 

2. Background subtraction has been modified to automatically occur when background data is selected.

3. Displayed data can now be processed in three types: 1) cross-section, 2) S(q,w), and 3) X(q,w). For cross-section and S(q,w), users can subtract a background specified by a user-defined constant factor. In the case of X(q,w), separate temperatures can be set for background and foreground.

4. Users can define axis titles.

windows version (2024/01/16)

• The scan simulation now allows outputting slice graphs with energy on the vertical axis and U or V on the horizontal axis.

• I have implemented background subtraction. The system automatically determines whether the background measurements were specific to a certain C2, as in the case of TOF, or measured across all C2, as in the case of TAS, and subtracts accordingly. 

※While the details will be documented in the manual at a later date, I'll provide a brief explanation here. Firstly, data within the tolerance range of the energy transfer are selected. Therefore, please note that the energy transfer should not exceed the measurement interval for proper subtraction. Then, the system selects the data closest to A2, followed by selecting the data closest to C2, and subtracts it as the background. This process is performed during file loading, streamlining the task of placing data into the three-dimensional mesh in a single step.

previous windows version (2024/01/13)

• I have resolved the issue with calibration.

• I have made some changes to the method of outputting figures.

※The overlay of graphs for 1D cuts is now updated to reflect the latest 1D cut graph. When performing certain operations in this program, the overlay of 1D cuts may appear on 3D and 2D cut figures. This behavior is not a bug but a designed feature. In such cases, please recreate the 1D cut graph and overlay it again as needed.

previous windows version (2024/01/10)

• Fixed minor issues.

previous windows version (2023/12/21)

• The masking feature for the detector has been implemented. 

• A functionality has been added to display the calculation results of Q in the calculation.

windows version (2023/11/24)

• I have resolved the bug where the graph was not displayed on a logarithmic scale by default. 

• When closing the window, all created graphs will be closed simultaneously.

windows version (2023/11/13)

• The UI has been slightly changed.

• The energy shift is corrected using the vanadium file.

• Added logarithm to graph display method.

windows version (2023/11/07)

• Enabled user to set energy transfer tolerance.

• Improved so that users can set the axis range of the displayed graph.

• Enabled to select other than Detector12 in TASmode.

• The design has been changed.

windows version (2023/11/02)

• The "recommendation" function now automatically inputs the bin size as well.

windows version (2023/10/31)

• Happy Halloween! 

• I have resolved the bug where axis labels were duplicated when changing the Y-scale in the 1D cut figure.

• TAS mode functionality was changed. Now, even if mcu is not defined, the app will display data for the scan.

• The specification that figure numbers are fixed in TAS mode has been changed.

windows version (2023/10/19)

• Users can determine the maximum intensity of the colormap themselves.

• The "3D view" slider now corresponds to "up", "down", "left", and "right" on the PC.

• The colorbar scale is now always displayed.

• Users can determine the maximum value of the y-axis for 1D cuts.
