Bugs fixes

Pro Version

• Color /New Class won't do a reanalysis if the new class is cancelled.
• Color /New Class will ask if user wants to reanalyse existing analyses (of current and/or all documents) or not if a class was added.

All Versions

• Recreate Last analysed region crash if activated after an analysed image was loaded.

Release date: 01 June 2022

• Multiple documents are now supported, which means the user can work on more than one image at a time. Each document window contains its own image, graphic and data file.
• Can now open TIFF "compressed" and JPEG 2000 image files.
• Can now open PNG image files.
• Right mouse click slider now shows by default the ActiveZone threshold value instead of 128.

• Modifications to the Simple Scanning Interface (in Image/Acquisition Parameters):
  • LA2400 Scanner 3rd Generation: Now works with TWAIN driver versions 6.5 (previous versions required 6.2).
  • LA2400 Scanners: The focus position can be modified (on the glass or above it).
  • The light source can be manually selected (when the scanner has more than one).
  • The image brightness can be increased or decreased.

• Can read Exif and GPS tags in JPEG files.

Release date: 10 March 2020

• WinCELL is 2.3 to 4.1 times faster thanks to its Multi-Threaded support (which does tasks in parallel). The speed increase varies in function of the complexity of the analysis (the processing done) and the number of processors/core/threads in the computer. Faster speed gain can be obtained by using higher end computers than those used by Regent in September 2019 to make the speed tests.
• Objects filtered out or rejected by the automatic analysis can now be revalidated (not all of them but most).
• The cells’ tilt angle can be specified per ring.
• The cells’ tilt angle can be changed after the analysis.
• It is now possible to create rectangular or circular Analysed Regions of a specified size.
• It is now possible to create a Vertical tile of regions of a specified size and gap between them.
• Analysis/Measurements can get the analysis settings of an active Analysed Region for review or to apply them to others.
• A manual and interactive object counter has been added (objects must be clicked in the image).
• Image Edition of the Cells’ Classification image (while an analysed region exists) are now cropped to the Active Analysed Region during drawing (they were cropped when edition ended - now they are before).

64-bit version:

• Can read some BigTIFF files
  

Bugs fixes:

• Row ordering works in more situations.
• Export/Import Analysed Regions were not working when there was a space in their name.
• Batch analysis now handles correctly images containing exclusion regions.

Release date: 10 April 2019

Bugs fixes

• Edit Sample Identification can now also change the Analysed region’s name.
• If a Calibration is loaded or its Parameters are modified while an analysis with Paths exists, the data are now updated in the data file as they should.
• Lumen length and width were 1 pixel oversized (bug was in WinCELL 2019a only).
• Touch Center paths not working (bug was in WinCELL 2019a only).

Release date: 20 August 2018

• New driverless protection keys (no more need to install protection key drivers). The key also now contains the WinCELL programs for distribution (not for execution).
• Individual object analysis speed has been increased.
• It is 14% faster than WinCELL 2018.
• A new setting for Huge images (2G, 3Gb or more) or images with a very large number of objects (> 200 000) has been added. When it is activated  the analysis is between 1.6 and 30.5 times faster.
• Ring Analysis Modifications:
  • New Ring Threshold. Its value is adapted in function of the distance from the ring beginning to allow for more sensitivity toward the latewood which lumen are often darker (due to their smaller sizes and occasionally presence of debris on the preparation).
  • It is now possible to load a WinDENDRO file to get ring boundaries positions from it instead of tracing them in WinCELL.
  • The number of rings is writtten in the Command area.
  • Analysis/Measurements can be activated when Ring Boundary Paths exist before closing the Ring Regions (to change the Huge image option).

• Centre HV and Maximum HV automatic cells measurement methods can now be applied to images with cells’ rows not perfectly horizontal. The operator must specify the tilt angle from the horizontal, up to 45 degrees.
• Cells with debris or wall residues in their lumen are now well measured. In previous versions, lumen length and width stopped at debris, now they are skipped over.
• 3 new Filters to reject cells with the following criteria:
  • Odd shape (their center is not in the cell’s lumen).
  • Wall(s) longer than lumen (row of cells not aligned, broken walls or with debris).
  • One wall (much) longer than the other.
    

• Options about what to do with rejected objects: keep them in object area and count but not in the morphology analysis or blend them with background (walls) = not an object.
• When loading an analysed image, the operator can choose to load or not 3 more groups of settings (those not loaded are overriden by WinCELL’s current’s settings).
  • Data Saving option.,
  • Color Classes and Groups definitions.
  • Image and debris Filtering.
• Measurements data text in the Command area has been revised, description of data writen is more detailed. Also when a rejected cell is clicked on more data about it is written.
• More lines drawn over the image can be drawn thicker (user selectable thickness). These are the lines used to identify: Lumens’ Length, Width and Perimeter, Analysed and Exclusion Regions boundaries, Regent’s Calibration Target and size Scale. Note that ring boundaries and cell’s paths thickness were already settable in earlier versions. (Ring Boundary Path thickness renamed Lines and Rings thickness)
• The Path Tracing working mode has a new icon.
• Image and Calibration files directories are uncoupled (changing one won’t affect the other, each one remembers its location independently of the other).
• The image will automatically scroll when the mouse cursor is moved toward its edge when defining an analysed or exclusion region or tracing paths.
• Color channel change is a thousand times faster.
• Windows menu is gone.

Bugs fixes

• A crash when the Cell Distribution Graphic’s Vertical scale was set to Log while there was no analysis.
• Useless reanalysis done when switching to image edition, path tracing and Region creation mode and no image edition had been done.
• Lumen length’s line color can now be changed.

Release date: 14 December 2017

• A new option to automatically switch to path tracing mode after the automatic analysis is done.

Bug fixes

• If a path under creation (not terminated) is deleted (Using Path/Delete Active Path), no more lines are drawn to the mouse cursor position and tracing of another path can begin right away.

Release date: 06 December 2017

64-bit version:

• Can load images larger than 3GBytes.

32-bit & 64-bit versions:

Modifications affecting all Analyses:

• Free style Analysed and Exclusion Regions (made with lasso) are faster.
  • Analysed regions are 22.1 to 35.3% faster than version 2016.
  • The coarsiness (resolution) of lasso style regions' boundary is user selectable, allowing a trade-off between spatial precision and analysis speed.
    
• Rectangular Analysed Regions are 19.4 to 33.3% faster than version 2016.

Ring Analysis modifications:

• A new Ring menu which holds Ring Analysis commands.
• Ring Analysis activation moved from Analysis/Measurements to Ring menu.
• A new command to Start/Stop Ring boundary path tracing.
• No more need to indicate the path type as "Boundary".
• Year number is asked only for the first ring (when tracing Ring boundary paths).
• Instructions in the Command area are more precise for Ring Analysis.

• When Ring Analysis is activated it will no more set the:
  • Data file format to WinDENDRO's
  • Individual Cell's Length & Width method (so you can use one which measures wall thickness).
    
• Ring regions now have a Sample Identification name and a Year (instead of just a year). Both are displayed over the image in Ring Regions.
• The Year can be edited in the Sample Identification window when closing the Ring Regions. By default it displays the year you entered when the first Ring Boundary path was created, but it can be edited.
• Ring Boundary paths can be modified after they have been traced before or after Ring Regions have been closed. You can move whole paths, segments of them and/or nodes (where segments connect to each other). If ring regions exist, the neighboring regions are updated automatically after edition.
• There are two more Ring Boundaries edition commands to reshape them:
  • An intermediary node can be Added to a path.
  • An existing node can be Deleted on a path.
• A ring can be inserted between existing rings or added after the last one (after Ring Analysis is done).
• Ring Regions can be moved and resized.
• It can save individual cell's data (and Ring widths) for Ring Regions (in WinCELL data file's format).
• Ring data (widths, area and more) can be saved in WinDENDRO format inside WinCELL's data files format. This is in addition to the previous WinDENDRO's files format (without individual cell's data).
• When Ring Regions are saved, their Sample Identification name is replaced by a new name made of the Sample Identification name, an unerscore character and the year (eg: Sample1 of year 2017 becomes Sample1_2017). This change was necessary so that files can be processed by XLCell (different analysis regions cannot have the same name).

Commands & Interface Modifications

• When loading an analysed image, the operator can choose to load or not 5 groups of settings (those not loaded are overriden by WinCELL current's settings):
  • Path type (to change the path type and update a previously done analysis),
  • Calibration,
  • Individual measurements settings (to change the length and width method,...),
  • Pixels classification,
  • Cells distribution graphic settings.
• Some commands can retreive parameters/settings of the Active analysed region for viewing or applying them to other analysed regions.
• Calibration/Pixel Size Method has been redesigned.
  • It no more has the option of 1 vs 2 images. It is always 1.
  • New Calibration won't load an image, will use current image for calibration.
• Lumen & Wall Distinction was renamed Lumen & Wall Detection and has been redesigned.
  • It can retreive parameters/settings of the Active analysed region for viewing or applying them to other analysed regions.
  • Its histogram is for the whole image if no Analysed region exists otherwise it is for the active Analysed region.
• Ask to save image after acquisition (in Analysis/Parameters) has been replaced by Save image before acquiring another and has those three differences from the former:
  • it will save the analysed image weather it comes from a file or scanner,
  • it will be saved after the analysis rather than before,
  • it won't ask for a name but simply append "An" to the existing name.
• Modifications to the cells distribution histogram above the image:
  • Its data can be saved in a new separate data type lines.
  • It can set the horizontal scale automatically.
  • Is no more limited to 200 classes (now up to a thousand).
  • Its settings are saved in configuration files.
• Keyboard shortcuts have been added:
  • Ctrl T, E or R to change the working mode:
    Ctrl + T to switch to path Tracing mode.
    Ctrl + E to switch to image Edition mode.
    Ctrl + R to switch to Region creation mode.
  • Ctrl O to Open a new document (Acquire an image from disk or scanner).
  • Ctrl S to Save the image.
  • Ctrl I to activate the Image/Display Image Area menu command.
• It now starts in Maximize state as a single window (instead of a window inside a window).
• User can choose the thickness of ring boundary and cell paths drawn over the image. Inactive cell paths are drawn thinner rather than dotted.
• The Command area is wider at startup to allow the display of more information and data.
• The Command area's Icons are larger.
• Analysis/Measurements has been separated in two commands (Analysis/Parameters and Analysis/Measurements).
• Save Original Image (With Analysis...) renamed Save Image (With Analysis...).
• Image/Save Displayed Image renamed Misc/Export Displayed Image For Other Programs
• Image/Save Image Region has been removed.
• Speed Memory Feedbacks names shortened.
• Path and analysed regions can be activated in sequential order using the tab key (and reverse order using shift tab). User can choose the thickness of ring boundary and cell paths drawn over the image. Inactive cell paths are drawn thinner rather than dotted.

Other Modifications

• Supports the new LA2400 scanner third generation (introduced in March 2017)
• Modifications to WinCELL data files:
• It saves optional data file title's lines (CELL, HISTO...) only when these data types are saved.
• One more optional title line can be saved, it's the WinDENDRO Title line. It is saved only when such data are saved in WinCELL format files.

Bugs fixes

• Misc/Print Whole Image when zoom was not 1.0, some items were not drawn correctly.
• "Zoom to fit" used to display horizontal lines at some magnifications.
• HISTO data lines, the data saved to files were not correct if 1) Normalised (in Data/Saving Options) was active and 2) Some objects were filtered out during the analysis.

Release date: 10 November 2015

• The first WinCELL version made and tested under Windows 10.

• When deleting all exclusion regions, Analysed regions are reanalysed just once.
• Perimeter measurement is more precise.
• Interface modifications:
  • Year Beginning and Ending are no more in the Sample Identification window. They are now in the Path Identification window displayed when a path is traced. They also have been renamed Substitute first wall and Substitute last wall of path. Substitution is required when the first and/or last wall(s) is (are) incomplete or cannot be measured.
  • Substituted first and last walls are drawn a different color.
  • The Command area is larger at startup to allow the display of more information and data.
  • When paths are traced, their name, length and number of cells are displayed in the Command area.
  • The analysis progress bar and message is displayed in the center of WinCELL's main window (to avoid hiding the title bar).
  • The display of Grouped and Splitted cell's count is off by default the Command area.

Bug fixes:

• WinCELL's MainWindow not visible at startup in very rare situations (easy to overcome by using default settings at startup).
• A situation in which changing the histogram's horizontal axis was very slow when there was very large numbers in its vertical axis.

Release date: 24 July 2015
