Cartool Releases

You can see here the changelog of the various releases of Cartool, to access the Download of Cartool itself, it's here.

Cartool 4698 Springtime 2017 edition

posted May 3, 2017, 3:28 AM by Denis Brunet   [ updated May 3, 2017, 3:37 AM ]

This is the latest edition of Cartool, with a lot of changes in the micro-states segmentation, inverse matrices computation, etc...



Cartool 3.52 (2847)

posted Oct 22, 2012, 10:24 AM by Denis Brunet

A maintenance release.

Inverse Solutions

  • Inverse display: switched back to the 4 Nearest Neighbors (4NN) instead of previously 1NN ("constant cubes"). Display looks better, and is fast enough.

  • Exporting results as volume: remains with 1NN for the moment, which means constant values in "cubes" around each solution points. Advantage being: no interpolation nor extrapolation, just the raw values ready for your own processing.

  • Better color palettes, plus 2 more: one contrasty black to yellow, and one which gives annular-like results.

  • Improved the display quality of the inverse itself when doing snapshots.

  • Solution Points: better detection of minimum distance across all points.

Other stuff

  • BrainVision files, reading format 2.0.

  • Many bugs fixed, too long to list (and to read?).


Cartool 3.52 (2693)

posted Oct 22, 2012, 10:09 AM by Denis Brunet

I am currently working on the new Spindle Detection feature. In the mean time, I upgraded & fixed many things:

  • Export Tracks
    Fixing some glitches.

  • Tracks Display
    Upgraded the Markers functionnalities.
    Bug when opening a content with positive data, the average reference could kick in (which it shouldn't).

  • EGI MFF format
    Updated to the latest format.

Cartool 3.52 (2500)

posted Feb 13, 2012, 10:33 AM by Denis Brunet

This version aims at tightening a bit the bolts, and should run much better for memory intensive processing.

Improvements

  • Scanning Markers boost: now it runs much, much faster (about 100x), even with filters on.

  • Export Tracks boost:
    • Speed dramatically improved, especially when using some filters (about 25x)!
    • Fixing some rare glitches, like wrong GFP in case of Baseline Correction, or wrong Average in case of re-referencing or rescaling.

  • Creating ROIs dialog:
    • There are now 2 lists of names the user can provide:
      • One is a kind of dictionary of the indexes found in the Mask volume;
      • The other one is the list of ROIs you actually want as output.
    • There is now a specific option for the AAL mask, its labels being directly encoded within Cartool.
    • An output ROI can merge multiple input ROIs together.
      (See the Help to get more details)
    • A few bug fixes, like with the center of the MNI template...

  • Statistics: made some internal changes to run with less memory, especially in case of .ris analysis!
  • Made many optimization regarding the memory use.
  • EEG Filters: some speed improvement.
  • MRI display now have a specific Histogram sub-menu, from the Filters menu.


Bugs

  • S-Transform in Frequency Analysis: the 0Hz output (average of the signal) could be outputted signed, even when saving the Norm or Norm2 of the signal!
  • Many little bugs won't see the end of winter...


Cartool 3.51 (2453)

posted Jan 24, 2012, 3:08 AM by Denis Brunet

Fixing the Brain segmentation (CSF / Grey / White matters) and improving the Bias Field Correction.

New features

  • Use a Mixture of Gaussians to compute the CSF / Grey / White matters level. Using these new levels to compute the grey segmentation more accurately.
  • Semi-transparent cursors, in tracks and frequencies display, for a less retina-destroying experience!
  • Added a Histogram menu in the Volume (MRI) filters:
    • Computing histogram,
    • Equalization,
    • Compaction (reverting equalization).
  • Improved the Bias Field Correction to behave better near the edges of the brain.

Bug fixes

  • Export tracks: many minor glitches fixed (exporting triggers, correctly reverting filters, tracks specification...).
  • Grey segmentation improved / fixed with the new Mixture of Gaussians.
  • Solution Points computation (Inverse Solutions) tuning.

Cartool 3.51 (2381)

posted Dec 12, 2011, 5:48 AM by Denis Brunet

A few bug fixes and new features.


Bug fixes

  • Creating Inverse Matrices: in some rare case (very high bias field near the neck), 'Gluing' the electrodes while coregistering the electrodes on the MRI could fail near the neck.
  • Electrodes files (.xyz or .els) orientation detection could fail in some rare case, when some of the 10-10 system electrodes were missing.

New features

  • EEG: a set of  3 Tracks Analysis tools (called from the  Selection|Tracks Analysis  menu), can help sorting out which tracks are flat, broken, noisy, or all at once.
    The aim is to detect useless tracks for an averaging. See the Help for more details...
  • EEG display: restored the ability to rescale some tracks individually.
    First select the targetted tracks (middle button as usual), then use Control + Shift + right click  (instead of Shift + right click).
  • MFF files: now you can Drag & Drop the MFF directory directly into any of the Cartool dialogs, Cartool will translate the directory into its corresponding signalXX.bin  files.
  • EEG display: revamped the Trigger/Marker display with darker text colors for better readability, and lighter colors in the body filling for better visibility.
  • EEG display: revamped the  Selection  menu with clearer description, organization, and a few more functions.

Cartool 3.51 (2345)

posted Nov 24, 2011, 9:03 AM by Denis Brunet

Mainly, this version is about reading the new EGI file format "MFF". There are quite some bug fixed, too...


Note: it is highly recommended to really restart your machine after you installed this version, as the Windows file association/icons have been changed (in plain english, which file has which icon).


MFF files

  • Files are store in a directory structure (package for Mac), which holds a lot of descriptive files something.xml and the data signalXX.bin (XX being a number).
    Don't delete, modify or rename any of these files, or you will break the coherence of this structure!
  • To open a MFF file in Cartool, simply use the signalXX.bin file.
    Another very convenient way to do is to Drag&Drop the directory structure itself in Cartool, which will open all the signal files it contains.
  • Triggers from the DIN input are simply coded with their values (as usual), like "123".
  • Triggers from the MultiPort ECI input are coded like "code:name":
    • code being the category of the trigger,
    • name being either the description, the label, or nothing if both are missing.
  • Multiport ECI triggers can also have keys, in which case Cartool add a trigger at the same position with a name "key=data".

Bug fixes

  • Normalizing MRIs: non-integer voxel sizes would lead to anisotropic voxels; origin could be wrongly set; size could be too small sometimes.
  • Big vectorized-types BrainVision files were very slow.
  • EGI .nsr files: triggers are now shown like "code:name", code being a category set by the stimulation program, and name the actual trigger; fixed reading some types of triggers (DIN with 255 values).
  • Switching to another EEG session/sequence now preserves (most of) the state of the window, like the bad channels, display type, etc...
  • Tracks display now has enough space for the channels' name.


Cartool 3.51 (2291)

posted Oct 24, 2011, 9:10 AM by Denis Brunet

OpenGL

  • Improved the way Cartool detects the best OpenGL mode.
  • There are now 2 options in the  File|Preferences|Graphic  menu:
    • Harware Acceleration can be forced on or off
    • 3D Textures can be forced on or off

Bugs

  • Creating inverse solutions: when interactively coregistering, there was a trail of meshes following the xyz.
  • Creating inverse solutions: fixing all cases when the xyz is already coregistered to the full head.
  • Grey matter segmentation improved.

Cartool 3.50 (2200)

posted Sep 19, 2011, 2:28 AM by Denis Brunet   [ updated Sep 19, 2011, 6:55 AM ]

Just an updated version of the official release, before switching to other stuff.

Cartool 3.50 (2193)

posted Sep 7, 2011, 3:41 AM by Denis Brunet

Lots of internal reworking that shouldn't really show up to the user...
Just in case, I put it as a Beta release.
