• Can now open TIFF "compressed" and JPEG 2000 image files .
• Can now open PNG image files.
• Traced roots can now be exported as an image of root skeleton lines to be opened and analysed in other programs (to produce new root measurements). It can be done interactively or in batch (see Image/ and Batch/Export Traced Roots Image).
• Analysis/Parameters has been split in two: Analysis/Parameters and Analysis/Measurements.
• Analysis/Soil Depth has been merged with Analysis/Measurements.
• Analysis/Soil Depth Limits has been merged with Analysis/Measurements.
• 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).

• Calibration/New Calibration command menu can be activated at any time there is no analysis. It now asks the user to load an image as the first step of the calibration and the latter is done on it.

Available: 17 March 2020

Bug fix:

• Cannot activate New Calibration.
  
  Workaround: Choose the "Intrinsic" Calibration Method. Load your image with a scale. Change the calibration method to "Scale in image". "New Calibration" is now active.

• Root Death and Gone sessions are now distinct and saved separately in data files.
• Gone roots can now be drawn 3 different colors in function of their living status the session they were declared Gone.
  • Dark green if they were Alive (the latter being drawn bright green as before),
  • Dark red if they were Dead (the latter being drawn bright red as before),
  • Blue if their living status was unknown.
• Modifications to Gaps
  • Gaps are saved in pa2 files (along with traced roots). They are automatically loaded when an image that was previously analysed is loaded.
  • They are faster (more visible when many of them exist in multiple images.
  • They can be used in batch reanalysis.
  • Gaps in uneditable (red) Analysed Regions now affects measurements and depth.
• Paths can be scaled upon importing or loading. This allow to preserve paths position, size and measurements values when images have been resized (dpi modified).
• Batch Rotate now preserve the image type (jpg vs. tiff) instead of always using tiff.
• If user presses “A” while moving the mouse cursor over a root, all roots are hidden (pressing “H” hides only the one under mouse).
• The Analysed Region’s name is drawn in dark green instead of light green in the Command Area (easier to read).
• When saving an image, Tron will suggest a name and display the last one used.
• Save image after acquisition has been removed.

Bugs fixes:

• Batch Rotate no more crashes in “Per Session” mode.
• The Depth value entered in the Sample Identification window had no effect on the analysis (when images came from a tif or jpg file, it was ok with images from scanner).
• A rare Crash after Pasting Session Roots (happened when focus moved out of WinRHIZO Tron then back in).
• When Link text infos is turned on in Display/Over Image and moving root(s) or node, there were jaggies (streaks) next to the numbers.
• Analysed Regions can be recreated after analysis is cancelled (simply by clicking the image) as in version 2019a and before.

• Calibration/New Calibration menu command can be activated at any time there is no analysis. It now asks the user to load an image as the first step of the calibration and the latter is done on it.

Available: 09 September 2020

Bugs fixes:

• Region/Import Gabs now imports all gaps, not just the first one.
• Depth gaps imported using Region/Import Gaps will now update the depth data.

• Crash and/or minor misbehavior after Root/Paste Session Roots was activated.

Available: 12 March 2019

Bugs fixes:

• Memory leak fixed. Some memory were not freed after an analysed region was deleted. It had for effect of memory loss after many analyses were done.

Available: 20 August 2018

• New driverless protection keys (no more need to install protection key drivers). The key also now contains the WinRHIZO Tron program for distribution (not for execution).
• Windows menu is gone.

Bugs fixes:

• Memory leak fixed. Some memory were not freed after an analysed region was deleted. It had for effect of memory loss after many analyses were done.

Available: 29 January 2018

• Root analysis can be restricted to a range of soil depths. This range can be modified before or after analysis (interactive or batch mode)to get root morpology in function of depth.
• Batch Re-Analysis can now be done in "per session" (tube) mode. It will do it in tube, location and session increasing number order (instead of file list order of the storage folder).
• Batch Re-Analysis saves error messages and analysed images to a log (.txt) file.
• Batch Re-Analysis also works with tube which first location is not 1.
• Roots can be selected more than one at a time (with rectangular image selections) to:
  • Move them.
  • Change their living status, observations and notes*,
    *(for the latters keep shift down while making the selection to edit the root properties).
  • Delete, Copy, Paste or Flip their direction.
• Memory use has been optimised resulting in less consumption, faster operations (load, save, copy, paste...) and the possibility to analyse images with much more roots.
• Free style (lasso) gaps are much faster.
• It is possible to analyse a rectangular sub-region of a Frame or Tube and to moved & resized them.
  • The last region of analysis can be recreated after it has been deleted (eg: to apply it on the same or other images).
    *Note in Per Session mode it works only when loading one image or a tube.

Interface & Commands modifications:

• Roots' drawing color can now be in function of their Observations values.
• It now starts in Maximize state as a single window (instead of a window inside a window).
• Root/Add Descending Link can now be activated while in Root Edition mode. WinRHIZO Tron will switch to root tracing mode automatically.
• Edit Root Properties can be activated in any working mode (using the menu command or the new keyboard shortcut below).
• Node diameter increase/decrease is now 1 pixel per key press instead of 2 and can also be less (1/2 if press 1, 1/3 if press 2, 1/4 if press 3).
• Keyboard shortcuts commands 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 P to display the Root Properties window (to change living status, observations and notes).
  • 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 Display/Image Area menu command
  • Ctrl G to activate the Region/Define Gap/Rectangular menu command.
• The Calibration/Pixels Size Method has been redesigned.
• Icons in the Command area have the WinRHIZO Tron brown color when they are selected and are centered in the Command area
• The maximum number of diameter classes in the root distribution histogram has been increased from 200 to 1000.
• WinRHIZO Tron switches to root tracing mode after image loading if no roots have been loaded (if ICAP naming scheme is active).
  
• When loading an image with the Previous session paths, if there no roots in Previous session and there are in the current, WinRHIZO Tron will warn the user before deleting them.
• Can now load the previous and next session or tube when their location number does not start at #1.

Bugs fixes:

• Misc/Print Whole Image
  • When magnification was not 1.0, gaps regions were not drawn correctly.
  • Roots were missing on the left side of the Analysed Regions.
• Can now delete gaps after after the analysis has been canceled (when no analysed region exists).

Available: 26 July 2017

Bugs fixes:

• Import Gaps is now working with Depth Gaps. Bug was present only in version 2015c.

Available: 01 May 2017

• Depth Gaps are 1 pixels wider to go up to the image right edge.

Available: 17 November 2015

Bugs fixes:

• Analysis/Import Traced Roots: Root, Segment and Axis session did not take the session number they were imported to (they retained the session number they were saved from).

Available: 01 July 2015

32-bit & 64-bit versions

• Can load twice as much images (or larger ones) as previous versions. An error message is now displayed when there is not enough memory to load them.
• Mutiple images loads 20% more rapidly.
• Soil depth measurements (minimum, maximum and average) are now available for the image, per Root, Segment and Axis. User can specify depth of tube first location relative to ground surface and the distance or gap between successive locations below it. The depth of each images can be calculated by WinRHIZO Tron or specified by the operator. Because of these new data saved in data files, XLRhizomTron 2015a is required to analyse them. Soil depth at the mouse cursor position is also written in the Information area.
• .pat files are now replaced by .pa2 files. The new format was required to accommodate new features and measurements of the current and future versions.
• Gaps modifications:
  • There is a new type of gap region called Depth Gap. It is rectangular but is made for vertical gaps between images (they encompass the whole width from left to right) and the area inside is considered when calculating soil depth (unlike the other types of gap).
  • Gaps can only be defined in an editable analysed region.
  • Gap regions cannot extend beyond an analysed region or overlapp them.
• At startup, when user chooses Default settings he can now choose between those for a scanner or a camera.
• Images without analyses can be saved as jpg.
• It is possible to automatically load a calibration file at startup.
• When importing paths, existing traced roots in the analysed region are not deleted.
• Segments can be renumbered using Fitter's convention after adding or deleting nodes.

Interface modifications:

• Roots and nodes are easier to select. There is a tolerance factor which greatly improves selection of thin nodes.
• The active segment is more visible (thicker than before).
• A root can be hidden temporarily (invisible) by pressing a key and bringing the mouse cursor over it.
• The display of roots' central line can be turned off.
• The Command Area is larger at startup by default (to display the new depth data).
• Volume data in the Command Area are written with 4 decimal digits instead of 2, other measurements with 3 instead of 2.
• Information about the Tube, Location and Session in the Command Area is displayed in one line instead of a few (and is visible even if there are no traced roots).
• The Gap menu has been renamed Regions (similar to other Regent's products). It holds the Gap and now the Edit Sample Identification commands.
• By default, Current instead of Previous is active to the right of Load analysis of in Analysis/Parameters. If ICAP is not active, it is inactive (it has no effect).

Bugs fixes:

• When deleting a segment, in some cases the analysis was not updated.
• Gaps can be activated by clicking them.
• Moving the first node of a root, sometimes the first segment was moved.
• Selecting a root, segment or node with an image selection now updates the Command area data.
• Paste Region roots and Paste Session roots are only active when they can be pasted (you have selected a region or session different than the one they were copied from).
• Roots copied from a region and pasted to another can now can be selected and edited as when tracing them. Previous versions (down to 2012) required to select them using an image selection rather than moving the cursor over and clicking them.
• Segments' identification number is now preserved when copying roots from a region and pasted to another.
• Roots are not highlighted while mouse button is down (caused the selection red rectangle to disappear and be shown in grey).

Commands/Features removed:

• Add Root Depth to name (now replaced by real root depth measurements).
• Color analysis.

Note:

• WinRHIZO Tron 2015a can read older .pat files made with WinRHIZO Tron 2007 or more. If you have files older than this, they must be opened and saved from WinRHIZO Tron2007 to 2014 before they can be read by WinRHIZO Tron 2015a.

64-bit version:

• It can now load and save jpg image files.
• It can now acquire images from 64-bit TWAIN sources (not from 32-bit TWAIN sources).

Available: 02 December 2014

Bug fix

• Import gap regions now updates the analysis as it should (to exclude roots in those regions). With previous versions the user had to define a region interactively (anywhere in the analysed image) to update the analysis after gap regions import.
