MossWinn 4.0 series release notes
 
 
  • 2012/03/28
    • The menu option Restrict velocity axis... has been added to the ART menu. It can be used to restrict the velocity axis—either only of the spectrum in the red-framed window or of all spectrum windows on the current desk—to a velocity range [vmin...vmax] to be given on the appearing dialog. (The resulting spectra are placed in new windows while the originals remain unaltered.)
    • Fixed a bug that occurred when in the FIT menu a 3/2 ↔ 1/2 source nuclide was changed to another 3/2 ↔ 1/2 source nuclide, and one (or more) of the subspectrum models previously set with the old nuclide selected was not available for the newly selected nuclide: in such a situation the subspectra in question remained either undefined or wrongly set for the newly selected nuclide.
    • Fixed a bug that prevented the correct loading of DLL-based fit models from the model library.
    • Fixed a bug that could cause runtime error when the Cal StD menu option was invoked and the number of free (fitted) parameters was less than two.
    • Fixed a bug that prevented printing of images of spectra included in MIDB records.

    • The Compound Summary of the MossWinn Internet Database now includes links to the publications associated with MIDB records of subscribers of the MIDB database service.
    • Further procedures of MossWinn have been complemented with their parallel computing counterparts that can offer higher computing speeds on PC systems based on a multicore processor. In the present version the following menu options of MossWinn can benefit from multicore computing:
    • Global
    • Cal StD
    • Find and apply best match
    • Fit using METHOD B (partial support)
    • Import Project...
    • Save all files of the project into a single folder
    • Save all files of the project group into a single folder
    • The menu option Set performance options... has been added to the SET menu. Its submenu option Parallel computation on multiple cores [ Enabled/Disabled ] can be used to enable/disable access to the parallel computing algorithms of MossWinn.
    • It is now possible to complement MossWinn with up to 30 user-programmed subspectrum model function libraries (in contrast with the earlier 3 possible libraries with the names SUB_DLL1.DLL, SUB_DLL2.DLL and SUB_DLL3.DLL). The libraries should be present in the code library directory of MossWinn, and they should have a file name corresponding to the mask SUB*.DLL.
    • The menu option Enable/disable libraries has been added to the SET menu. It can be used to enable/disable the loading of user-programmed subspectrum model function libraries from the code library directory of MossWinn.
    • MossWinn now supports the estimation of the standard deviation of fit parameters for datasets with non-Poisson noise distribution, when the variance of individual counts cannot be taken to be equal to the value of the counts themselves. (This situation can be realized, e.g., by the normalization of a Mossbauer spectrum.) The corresponding calculation mode is in effect when in the FIT menu the Simple squared deviation or the Absolute deviation fitness functions are selected via the Chi menu box.
    • In the FIT menu a right-mouse-button click on the CalStD menu box now allows one to save the correlation matrix of the fit as GIF image.
    • In the FIT menu subspectra based on user-programmed subspectrum model function libraries can now be added to the current model via the submenu options New Subspectrum (DLL) and New Shared Subspectrum (DLL) of the Add menu.
    • When in the FIT menu a formerly saved fit model is selected, it is now applied to the current spectrum by preserving the relative amplitudes of the included subspectra. One can use the LinFit menu option to achieve an independent fit of the amplitude type parameters.
    • Three new menu options (Save all shown temporary files into a single folder, Save all files of the project into a single folder, Save all files of the project group into a single folder) have been added to the HDO menu.
    • The menu option Recreate distributions without fitting has been added to the SFT menu. Select this option to recreate and invoke distribution curves (if any) associated with fits accepted earlier for the spectra on the current project desk.
    • The F5 keyboard button can now be used to make the window of MossWinn remain visible in front of other windows even if the latter have received the focus. Once in this mode, press the F5 button again to return to normal mode.
    • Fixed a bug that could lead to memory leak.
 
 
 
  • 2011/07/30
    • Two new menu options have been added to the PRN menu, which allow one to save the image of the red window or that of all windows on the screen in the GIF image format.
    • The First Author field of MIDB records is now a required field independent of whether the publisher is the corresponding author or not.
    • Fixed the bug that in some situations could prevent the MIDB browser to return answers to database queries in the correct order.
 
 
 
  • 2011/05/01
    • A new Mossbauer spectroscopy database service – named MossWinn Internet Database (MIDB) – has been developed, and is now available for access via the internet by the help of the MossWinn program. The database allows subscribers to search and browse existing records, as well as to publish, edit or withdraw their own records in the database. The MIDB functions are accessible via the DB menu box in the FIT menu. See the online help, the MIDB Publisher's Guide, the MIDB Subscriber's Agreement and the MIDB manual for further information.
    • The Split distribution submenu option was added to the Constrain menu box of the FIT menu. The option can be used to split a previously set distribution at some intermediate distribution parameter value. As a result, the distribution will contribute to the fitting curve by two separate subspectra.
    • The All subspectra submenu option was added to the Remove menu box of the FIT menu. Turn to this option in order to remove all shared and unshared subspectra from the fit model associated with the current spectrum.
    • The Spectrum parameters and Isomer shift reference submenu options were added to the Set menu box of the FIT menu. By the help of the former one can alter spectrum parameters directly from the FIT menu, whereas the latter can be used to declare the isomer shift of the isomer shift reference material associated with the current source nuclide. (The latter information is utilized when the fitness of MIDB records is evaluated with respect to the current spectrum.)
    • When the FIT menu is entered with a formerly fitted spectrum, the constants underlying of linear models expressing magnetic splitting (if any were accepted earlier for the spectrum in question) are now updated automatically to reflect the current set of nuclear constants (gyromagnetic factors).
    • Parameters of linear models whose underlying constants (i.e. meaning) have been changed (on the details page) – in comparison with the corresponding default values – are now denoted by navigation menu shapes with a highlighted center (see example).
    • There was a problem with the interpretation of the Jump Up Rate / Jump Down Rate and Jump Rate parameters of the Blume-Tjon Two State Magnetic Relaxation (Powder) and Tjon-Blume Jahn-Teller Quadrupole Relaxation (Powder) theories, respectively: MossWinn works with and reports the logarithm of the angular frequency of the relaxation, which was not emphasized in the manual. The corresponding sections of the manual have been updated to reflect the meaning of the relaxation rate parameters properly.
    • Fixed the bug that could prevent the Global search method in the FIT menu to perform efficiently for some special but simple cases.
    • Fixed the bug that could make MossWinn to enter an infinite loop when the MPD → Rename Current Project menu option was selected.
    • Fixed the bug that prevented the MPD → Rename Project Group... menu option to work correctly in some situations.
 
 
 
  • 2010/12/19
    • Fixed the bug that prevented MossWinn to fit distributions to spectra with the first-channel count being fixed (set to zero).
 
 
 
  • 2010/10/20
    • Right mouse button functionality was added to the EDT menu: the corresponding right-mouse click popup menu allows one to set a certain spectrum parameter to the same value for all the data windows on the current project desk.
    • The option Delete gray-framed (temporary) windows was added to the right-mouse click popup menu of the DEL menu.
    • Fixed the bug that prevented the option ARR → Arrange by TEMPERATURE [K] from working correctly when applied to distribution windows newly prepared via the SFT menu.
    • Fixed the bug that prevented the option DEL → Delete invisible windows on the current desk from working correctly.
    • Fixed the bug that in some situations made the SBC menu respond as if the left mouse button was pressed though a right mouse button functionality was invoked.
 
 
 
  • 2010/06/02
    • Fixed the bug that caused the opening of multiple help pages when a help ellipse was pressed on.
 
 
 
  • 2010/06/01
    • Support was added for left-handed mouse operation mode (i.e. swapping of the left and right mouse button functions).
 
 
 
  • 2010/05/29
    • Support was added for Lite version licenses.
    • The Ctrl-key functionality on exit was eliminated because premature exit could lead to memory leaks and associated error messages.

    • This is the first release note concerning MossWinn 4.0Pre, the first member of the MossWinn 4.0 series. The main changes compared to version 3.0i xp are listed below.
    • The code of MossWinn 3.0i xp was ported from Borland Pascal 7.0 (DOS, 16 bit) to Delphi 2007 (Windows, 32 bit) to make it suitable to run on newer MS operating systems including MS Windows XP, Vista and 7 (32 bit and 64 bit versions).
    • Special effort was made to preserve the original user interface, while at the same time achieving considerably higher execution speeds via the general optimization of the code for Windows environment.
    • The built in nuclear constants were updated to their latest values.
    • A html-based context sensitive help was developed.
    • Support was added for the automatic and manual update of the help files and the main executable through the internet: if allowed, the program can automatically detect, download and install updates when they are released.
    • Support was added for windowed and full screen operation modes.
    • Support was added for mouse wheel (scrolling up or down) events.
    • Support was added for long file names.
    • Support was added for the extended ASCII (code page 437) character set.
    • Support was added for Windows copy/cut/paste clipboard functions in textual and numeric edit boxes.
    • Support was added for Windows copy clipboard functions concerning graphical images, tables (comma-delimited text) and fit reports (simple text).
    • Support was added for the export of spectrum images in JPEG format.
    • Support was added for Arial, Cambria and Times New Roman fonts on printed/copied graphical spectrum images.
    • The maximum number of loaded datasets/subspectra was increased to 1000.
    • In the FIT menu, the correlation matrix of fit parameters can now be copied to the clipboard as a table (comma delimited text) or as an image.
    • The MLS and FLT menus were further developed and now allow for the continuous adjustment of the noise filter's cutoff frequency and of the line width of the deconvolved Lorentzian via the corresponding slides.
    • The auto-copy of original data files is now a wired-in feature: MossWinn will not alter the original data.
    • Supplementary information (of arbitrary kind) in the original data files is now copied along with spectral data into derived data files even if the information is not used/recognized by MossWinn.
    • MossWinn can now be instructed to extract the velocity axis from data files with special columnar format.
    • MossWinn can now be instructed to interpret and load any data file according to a given special format, even if the data file does not match the criteria specified previously for the special format in question.
 
 
 
  • Upgrade earlier versions to MossWinn 4.0Pre.
