Change Log 2007

  • (26 Dec 2007) Remove leading and trailing whitespace from study names and

foci names so that comparing the names functions correctly when updating foci study links by matching foci names to study names.

  • (26 Dec 2007) Upgrade to QT 4.3.3 on Linux and Windows.
  • (24 Dec 2007) Added "-surface-roi-statistical-report" to

caret_command.  This new operation runs a statistical report on the nodes selected in a surface region of interest file.

  • (20 Dec 2007) Added the list of drives to sidebar of the File Dialog.
  • (19 Dec 2007) Added new Surface

Overlay System that make each overlay independent from the others.  As a result, this allows the use of a different data type in multiple overlays.  For example, three metric columns may be displayed with each column in a different overlay.  In addition, there are now three overlays and one underlay.

  • (19 Dec 2007) Fixed problem with updating study metadata links

for foci by matching the focus name to the study name.  This operation failed when a focus did not have any study metadata links.

  • (18 Dec 2007) Fixed scene problem with probabilistic atlas


  • (13 Dec 2007) Added a "JPEG Image" movie mode to the Record Main

Window Images Dialog.  The intent is to use a program such as Apple's iMovie, Apple's QuickTime Pro, Adobe Premiere, or Microsoft's Media Encoder to convert the JPEG image sequence into a movie.

  • (13 Dec 2007) Added a button to the Viewing Window Toolbar

labeled "Swap".  When pressed, the brain model in the viewing window and the main window are swapped.

  • (07 Dec 2007) Updated QT to 4.3.3 on Mac OSX.
  • (06 Dec 2007) Added two search

capabilities to the Caret Help Window.  The first search method searches the loaded help page.  The second search method searches all help files.

  • (06 Dec 2007) Fixed problem with metric animation interpolation

using an invalid index to get/set node coloring during color interpolation.

  • (05 Dec 2007) Add All On/All Off buttons to Identify Dialog's

Filter tab.

  • (05 Dec 2007) Modifies reading of areal estimation files for

selective column loading.  Added an Areal Estimation submenu to the Attributes Menu that allows for clearing of Areal Estimation File columns and moved the Generate Areal Estimation Map menu item to this submenu.

  • (05 Dec 2007) Fixes for recording on the Recording Dialog and the

Metric Settings Display Control page.

  • (05 Dec 2007) Add control that sets the maximum distance a focus

may be from the surface to the Foci Attribute Assignment Dialog.

  • (04 Dec 2007) Modified SureFit algorithms partial hemisphere

padding so that the padding receives a light amount of erosion.  Without this erosion, most nodes in the CUT.FACE region were removed by the polygon simplification algorithm leaving many sliver triangles in the surface.

  • (03 Dec 2007) Add option to set the number of padding slices when

processing a partial hemisphere with the SureFit segmentation algorithm.

  • (30 Nov 2007) Added import of MNI OBJ Polygon File.
  • (30 Nov 2007) Finished removal of all QT3 Support code.
  • (30 Nov 2007) Add Paint Name page to the Display Control

Dialog.  This page allows selection of paint names for display.

  • (29 Nov 2007) Fixed problem with padding of partial hemisphere

segmentations.  The padding was using the last slice but should have been using the second to last slice.  See

  • (29 Nov 2007) Removed mouse mode control (13 Nov 2007). 

Modified the Toolbar View button so that it now contains a small arrow.  Pressing this arrow displays a menu for common mouse modes.  In addition, the context menu (right click on Linux and Windows, CTRL-Click on Macs) display a mouse mode menu.

  • (28 Nov 2007) Improved reading of NIFTI volumes that use QFORM

for orientation information but probably not totally correct.

  • (28 Nov 2007) Fixed crash when File Menu->Set Current

Directory was used.

deselection of a hemisphere for assignment.

  • (19 Nov 2007) Fixed display of foci geography attribute in

identification dialog.

attribute file (e.g. metric) having a blank column shown as selected on the Display Control even though there is data loaded.

  • (28 Sep 2007) Fixed problem with unicode characters in strings

returned by PubMed.

  • (20 Sep 2007) Fixed cell density to metric operation crash that

of "caret_command".  "caret_command" now includes the functionality of the programs "caret_file_convert", "caret_copy_spec", "caret_zip_spec", "caret_metric", and "caret_map_fmri".  As a result, these programs have been eliminated.  Since "caret_command" has been rewritten, the Script Builder Window, available from the Window Menu, has also been eliminated since it is incompatible.  In place of it, for now, is "Caret Command Executor", which provides a user-interface for executing all of caret_command's operations.  Since all of the metric/shape statistical operations are in "caret_command", and Caret Command Executor provides an interface to them, the Attributes Menu->Metric and Shape statistical operations menu has been eliminated.

  • (27 Aug 2007) Do not limit the size of foci.  If being drawn

as OpenGL points do not allow the size to  exceed the maximum OpenGL allowed size.

  • (27 Aug 2007) Add "Strongest Voxel" algorithm for mapping

functional volumes to surfaces.  For each node, its value is the value of the voxel that is furthest from zero in the local neighborhood.

left and right hemispheres.

  • (10 Aug 2007) When "Update Focus PubMed ID if Focus Name Matches

Study" no longer clears the study link when the PubMed ID is not equal to the Project ID.

  • (31 July 2007) Fixed reading of gifti data arrays that had base64

encoding.  Using "const QByteArray ba equals text.toAscii(); and const char* textChars equals ba.constData();" instead of "const char* textChars equals text.toAscii().constData();" fixes the problem.

  • (27 July 2007) Allow multiple spec files to be selected on the

Open Spec File Dialog.  Multiple spec files are selected on the dialog by using the CTRL or SHIFT keys and the mouse to select files.

  • (24 July 2007) When caret is started with "-loadspec

spec-file-name" allow the entry of multiple spec files so that multiple spec files my be loaded simultaneously.

  • (19 July 2007) In Caret file name generation, ignore and no

longer use the date in the file name.

properly handled when appending a color file.

  • (13 July 2007) Add buttons on the Surface Region of Interest

Dialog for saving or loading the current node selection.

  • (06 July 2007) Fixed abort that occurred when creating a new spec

file on the spec file dialog.

  • (05 July 2007) Display study information when a vocabulary entry

with a link to study metadata is identified.

  • (05 July 2007) Correct reading/writing of study metadata links

for vocabulary files.

surface for topological errors (handles).

  • (29 June 2007) If subject/species/hem not provided by spec file,

guess at their values by examining coord and topo file names.

  • (29 June 2007) Add "-paint-composite" to caret_command.
  • (22 June 2007) Add a full width half maximum algorithm to metric

smoothing.  This algorithm smooths until the FWHM is achieved or the maximum number of iterations is reached.  The FWHM estimation is based upon formula 2 of the Hagler et. al. article from NeuroImage 33 (2006) 1093-1103.

  • (20 June 2007) Add a "1.0 - value" operation to volume and metric

math operations.  The intended use is convert P-Values to "Q-Values".  If the users wants to threshold, say less than 0.05, it cannot be done in Caret since caret thresholds "above" values.  So, using this operation will allow the user to threshold greater than 0.95.

  • (19 June 2007) Remove all metric smoothing options except average

neighbors from the MetricFile.  All algorithms remain in BrainModelSurfaceMetricSmoothing.

  • (19 June 2007) Add

multi-fiducial mapping of paint volumes to surfaces.  These options include mapping to the PALS atlas' individual cases, mapping to the average fiducial surface, and in place of average to all cases a most commonly mapped ID for each node.

for generating a cerebral hull volume from a fiducial surface.

  • (13 June 2007) Add selection of nodes within a latitude/longitude

range on the Surface Region of Interest Dialog.

  • (13 June 2007) Fix volume handle finder handle selection so that

it uses stereotaxic coordinates which will work when the underlay volume is a different dimension than the segmentation volume.

  • (12 June 2007 Add -metric-or-shape-stat-kruskal-wallis to

caret_command which performs a Kruskal-Walllis (non-parameteric one-way ANOVA).

  • (12 June 2007) Increase number of surface outlines shown over

volume slices and move the controls from Display Control's Volume Settings page to a new page, Volume Surface Outline.

  • (12 June 2007) Rebuild QWT libraries due to new QT libraries

installed on 08 June.

  • (11 June 2007) Added a method to the foci projection file that

eliminates all foci not in a list of specified indices.  This will be used by WebCaret.

  • (11 June 2007) Changed the following caret_command operations so

that they only the name prefix is specified for all output files: "-metric-or-shape-stat-paired-t-test", "-metric-or-shape-stat-one-sample-t-test", "-metric-or-shape-stat-interhemispheric-clusters", "-metric-or-shape-stat-anova-one-way", "-metric-or-shape-stat-two-sample-t-test", "-metric-or-shape-stat-coord-diff".

SureFit Segmentation Dialog to generate topologically correct surfaces.  This option is off by default.  If turned on, a dialog informs users about issues and limitation of this option.

  • (05 April 2007) When generating a surface and maximum polygons is

selected, do not perform any polygon decimation.  Previously, if maximum polygons was selected, there was some polygon decimation performed if it could be done with very minimal or not change in the shape of the surface.

is entered on the File Menu->Save Data File Dialog.

  • (02 April 2007) Add a Link button next to the DOI/URL on the

Study Metadata Editor.  When pressed, it will use the DOI/URL to show the article in a web browser.

Separated Value File format so that the column names are case insensitive.

  • (22 Mar 2007) Added -volume-segment-mask-creation, which creates

a volume mask from a group of volumes, and -volume-mask-volume, which applies a mask volume to a volume file, to caret_command.

  • (22 Mar 2007) Added "Correct

Fiducial Surface Topology (Remove Handles)" to the Surface-Topology menu.  This operation will remove all topologial errors (handles) in the main window fiducial surface.  It does this by discarding nodes around handles and retessellating the surface.  While the resulting surface is topologically correct it is not necessarily anatomically correct.

  • (22 Mar 2007) When drawing 3D borders, allow the mouse to rotate

the surface if the ALT key is depressed.  This should help with drawing flattening and registration borders as it will allow the borders to be drawn on 3D (inflated, fiducial) surfaces instead of the flat map and the compressed medial wall surface.

  • (22 Mar 2007) Add selection of nodes that are crossovers to

surface region of interest dialog.

  • (15 Feb 2007) When reading cell/foci files and cell/foci

projection files, check for an invalid structure for a cell/focus.  If the structure is "invalid" set the structure to "right" if the X-coordinate is greater than zero or set the structure to "left" if the X-coordinate is less than zero.

  • (15 Feb 2007) Some cell/foci files were not having their

structure read correctly but it seems to now be fixed as a result of updating QT to QT 4.2.2.  This problems was found when unit testing of foci rendering failed.

  • (15 Feb 2007) Added unit testing comparison for cell & foci


  • (14 Feb 2007) Updated QT to QT

4.2.2 since it is supposed to contain fixes to bugs that I had reported.  Unfortunately, not all the bugs they claim to have fixed are corrected and they have added new bugs such as a Q3FileDialog that is too large to fit on the screen.
