Release Notes
The following list shows a history of the development and the major changes of previous versions of ROXAS.
.
17 September 2013 - v1.6.0.0
- ROXAS main window, Batch
processing: new option to recalculate output of previously analyzed images.
This option is useful when parameter calculation was improved (see below) or
extended to quickly create updated Excel output files.
- ROXAS main
window, Summarize ROXAS Output:
new option to restrict overall summary to specific years (period).
-
ROXAS main
window: periodical appearance
of a button to delete the “IpRef.cal” file that stores the used spatial
calibrations; when this file gets too large, loading and creating
spatial calibrations - and therefore analysis in general - slow down.
- Spatial calibration in cross-sections: the default location of the cross-hair specifying the center of the
sample is now in the image center.
- Manual editing: moved
the ‘Change the checkpoint resolution of ring borders to ...’ option to the new ‘Editing Utilities &
Options’
- Manual editing: moved the
‘Show/hide Settings’ option to the ‘Editing Utilities & Options’
- Manual
Editing, Editing Utilities &
Options: new option to
split the image into overlapping sub-images; this speeds up conduit editing in
very large image files and avoids a bug of IPP that does not support the Magic Wand
tool for conduit drawing in very large images.
- Manual
Editing, Editing Utilities &
Options: new option to represent the outlines of conduit lumina as filled objects and to customize the
outline color
- Manual
Editing, Editing Utilities &
Options: new option to automatically show and hide
conduit outlines for a customizable number of repetitions and a customizable repetition
rate
- Improved algorithm for ring width
measurement in rings with oblique and non-parallel borders as often
appears towards the
stem center. The obliqueness of both the inner and outer ring border is
now independently considered. Before, only the obliqueness of the outer
ring border was considered, assuming the inner border would
run more or less parallel.
- Improved algorithm for
assigning conduits to annual rings: now interpolating between checkpoints of ring borders. Before, conduits
were related to the closest checkpoint.
- Improved algorithm for
detection of touching neighboring vessels (vessel grouping): take angle of major
axis into account.
Before, vessels were always assumed to touch with their flat side (the major
axis).
- New output (in summary
file): mean hydraulic diameter
- New output (in summary
file): vessel group size frequency distribution (absolute and relative)
- New output (in summary
file): relative position of largest/smallest conduit and max3 within annual
ring
- Generally streamlined
automatic analysis to better handle very large images.
- Bug
fixes and general improvements of stability.
.
14 March 2013 - v1.5.0
- ROXAS main window: added
function to summarize all ROXAS output files of a folder and
together with additional statistics such as percentiles of conduit size,
conduit size
contributing xy% to theoretical conductivity, conduit size frequency
distribution and percentage of grouped conduits depending on conduit
size
classes
- Manual editing: enable to draw several missing rings in one go.
- Manual editing: speed up redrawing of conduit outlines that were added using the trace tool.
- Manual editing: replaced some of the old instruction windows (draw new ring, split conduits, draw conduits) by windows
that can be represented in minimal view and stay in place after moving from the
central startup position to a more peripheral position. This avoids obstructing
any image target regions when editing
- Advanced settings: omit conduit grouping
analysis if double cell wall thickness is set to 0 to speed up processing. This adjustment may be
particularly sensible in coniferous wood
- Enable writing output in Excel format 2007 and higher (*.xlsx) if present. In Excel
2007 and later, the maximum number of columns and rows is much higher (up to 16,384 columns and 1,048,576 rows), which allows to
write data from much larger samples. If you load a previously analyzed image and do some editing, there will be a
new *.xlsx output file besides the old *.xls file. The latter can be deleted.
- Make
ROXAS fully independent from MS Windows Regional Settings (allow any
regional settings for import/export/exchange of ROXAS settings files and
Excel
output files). In earlier versions, some Regional Settings (e.g., NL,
RU) using comma (",") instead of point (".") as a deliminator for
decimal numbers caused problems.
- Bug fixes and general improvements of stability.
8 November 2012 - v1.4.0.4
- Tree cores: implemented automatic origin selection during spatial
calibration.
- Tree cores: improved algorithm that adjusts ring width measurements
to inclined (non-horizontal) ring borders; should give more accurate
values than before
- Manual editing: added functionality to change checkpoint resolution of
ring borders
- ROXAS project files (*.rpf) still work even after moving to another
folder as long as the associated image and spatial calibration files (*.cal) are
moved as well. Before, the image path in the rpf-file had to be updated
- Bug fixes and general improvements of stability and user friendliness.
5 June 2012 - v1.4.0
-
Decoupled all previously coded species specific settings to settings
files (*.rsf) to streamline the ROXAS application file. The settings
files are now provided to registered user as part of the installation
folder.
- ROXAS main window: added “Manage calibration files”
option to open the user's application folder that contains the settings
files (*.rsf) to ease management of ROXAS settings.
- ROXAS main window: added “Adjust General ROXAS settings” option to change the default startup settings
- Tree
cores, spatial calibration: allow Y origin to be offset >32’768
pixels out of the image. This allows to narrow the specified sector,
which improves quality of automatic ring detection.
- New output
parameter: replaced previous "Vessel Multiple Fraction" (VMF) by more
intuitive "Mean Group Size of Grouped Vessels" (GSGV), defined as
(100-VSF)/VMF
- Settings window, Annual ring recognition: added smaller steps in
“Steps of ring border trajectories” to improve accuracy of ring tracing in very long images.
- Advanced Settings window, Miscellaneous: added "Color of
vessel outlines" option
- Bug fixes and general improvements of stability and user friendliness.
5 September 2011 - v1.3.0
- Implemented ROXAS Pro with full functionality vs. ROXAS Basic version without batch processing functionality.
- Added control for parenchyma analysis in ROXAS main window.
- Manual editing: implemented Undo option for the last ring and vessel editing operation.
- Improved output of AOI-based analysis: area-sensitive statistics calculated on AOI area-level in global and annual ring output.
- Improved ROXAS setup file.
- Completely re-structured and extended ROXAS Reference Manual.
- Bug fixes and general improvements of stability and user friendliness.
21 March 2011 - v1.2.0
- Decoupled
ROXAS species settings file from compiled version and made it
accessible as text-file. The settings files are listed in ROXAS main
window > species selection field.
- Added additional options in Advanced window to include all relevant parameters needed for adjusting to a new species.
- Excel
output file adjusted to include all relevant parameters in settings
tab. Layout is identical to settings text file and may be copy-pasted
into a text file to create a new settings file (extension: *.rsf).
- Allow
user to define additional AOI’s (besides sector and xylem outline) to
which analysis should be limited. In tree cores this may be useful to
follow xylem outline (mask around core) or to select tracheid files.
Vessels at the AOI borders that may be cut-off are either fully included
or excluded depending on there center coordinates. All relevant
AOI-level parameters that cannot be easily derived from other statistics
are written separately to the output file.
- Improved local contrast enhancement in image processing.
- Added
Roxas.ini file which contains easily changeable running options that
are not associated with species settings files, e.g. the default species
on start-up.
- Bug fixes and general improvements of stability and user friendliness.
8 March 2011 - v1.1.3
- Cross-sections: use trace circumference that are manually drawn by the user as the outmost ring boundary.
- Cross-sections:
automatically delete vessels (manually) drawn outside of specified
angular sector and very small vessels that are most likely artifacts of
manual vessel splitting/drawing.
- Delete vessels outside of
outmost ring that may be present due to manual editing or by the small
interpolation difference between xylem outline and outmost ring trace.
- New parameter: potential hydraulic conductivity.
- New parameter: vessel grouping index, vessel solitary fraction and vessel multiple fraction (sensu Carlquist 1988/2001)
- Manual editing: allow selecting multiple ring traces to delete in one go.
- Manual editing: new tool to delete several vessels within a user-defined AOI.
- Manual editing: allow multiple vessel tracing in one go.
- Adjusted to Excel 2007 and later: Excel 97-2003 (*.xls) used as default file format.
- Bug fixes and general improvements of stability and user friendliness.
16 January 2010 - v1.1.2
- Created ROXAS installation file including all required ActiveX components and DLL that might not be installed on host machine.
- Adjusted to IPP 6.x: >100’000 objects/vessels can be recognized.
- Several minor bug fixes in batch processing
12 December 2008 - v1.1.0
Main window:
- Added several control options for the way Analysis should be performed:
- "Tree
core(Y) Cross-section (N)", "Consider outline trace in analysis" (only
available/relevant in cross-sections!), "Find outline automatically"
(only available in cross-sections!); "Only global xylem analysis",
"Extended visual output"
- Added a batch spatial calibration functionality.
- Added option to prepare project file for batch running the automatic analysis of several images.
- Added a batch tool for running the automatic analysis of several images.
Automatic analysis:
- Cross-sections: implemented stepwise analysis of sub-regions in large images to prevent
crash in IPP 4.5 when >16,384 objects are found during vessel
extraction.
- Improved vessel extraction algorithm.
Manual editing:
- Added
button to only update outlines. Give user choice to re-edit after
updating (useful in cases where manipulation errors occurred).
- Allow consecutive hitting on junk objects to delete them.
- Added function to split merged vessels.
- Added
option to only output essential visual data and not update/draw
illustrating images that show Earlywood vessels, Earlywood Border
vessels and assignment of vessels to rings.
User friendliness, system stability:
- Allow to load previously saved annual ring boundaries and vessel outlines accessible for re-editing.
- cross-sections: save and re-use manually drawn xylem outlines
- Generally improved user guidance and information
- Bug fixes and general improvements of stability and user friendliness
12 February 2008 - v1.0.3
- Cross-sections: polar grid laid over source image to ease the selection of the sector to
analyze.
- Tree cores: implemented stepwise analysis of sub-regions in large images to prevent
crash in IPP 4.5 when >16,384 objects are found during vessel
extraction.
- Cross-sections: algorithm to approximate outline trace. The radial
changes in the tangential direction are used to guide algorithms in
“Annual Ring Determination”. This will improve handling of eccentric
roots.
- Added button to allow the user to show/hide the outlines of vessels in
i) “Settings”-window > “Vessel Extraction”-tab and ii) “Manual
Correction”-window. The user can now flip between vessel outlines
on/off, which will ease distinction of wrong and true vessels during
calibration and manual corrections.
- Automatically load the Annotation window when needed in “Manual Editing”.
- Improved writing of data output to Excel. Now 25x faster than before.
- Bug fixes and general improvements for stability and user friendliness.
30 June 2007 - v1.0.0
