"Brain EdgeWave Express" workflow:  corrected the aborted processing defect when submitted volume is 4D.
In most dynamic models:  improved checking of the required Dynamic dimension to be present and have the proper values.
T1-inversion recovery (MODULUS):  parametric fitting and T1-map for the whole slice.  Processing time is 3 min/Slice but could be substantially improved.

T1-inversion recovery model:  completely reengineered the model, implemented a Global Fit solution, updated the user interface.

Data curve (Red),  Model Curve (Black)

Dynamic model  "T1 mapping using inversion-recovery - MODULUS" : made correction to allow data to have repeating TI-values.
MIDAS .time format::  Added improved heuristic about the "Starting Index Convention"
.IM file RAW load:  added special processing in case the time values are not in chronological order.
Fixed an error in "ChangeEndianess" function that was causing an aborted load of .im files.

FVX file format load:  Implemented function that ensures the Chronological order of Dynamic coordinates. 
Performed a major reengineering of a composite DynamicCoordinate structure in FireVoxel.  This influences the way the dynamic coordinates are stored and used.

Liver DCDI:  Blood Vessel removal Dialog:  corrected an error with displaying the percentage of the Vessel and Liver.

Sulci Base Print with the Sulci Depth.  This is a quantified print, not a volume rendering.
Units are in 0.01 mm.  All processing and print are produced by FireVoxel, no additional software.



The above image is dual with the "Binary SulciBasePrint" which could be directly derived from the above.
SulciBasePrint:   Initial result of Sulci Depth maps (raw data to be improved).  Note!  THIS PICTURE IS NOT A VOLUME RENDERING.  Instead it is a fully quantifiable base print.  Signal intensities are in 0.01mm units representing Sulci depth

Added ".image"  to the list of the supported DICOM extensions.
BrainPrint - SulciBasePrint:

Can be now generated in FireVoxel directly.  Below is an intermediate result of binary SulciPrint, without Sulci Depth information (next step).  Note that the visible width of the Sulci is highly influenced by the User-define "Sulci minimal depth parameter"

Implementing the "Sulci Base Print"  function for the BrainPrint project.

Finalized, documentd and sealed 2 most promising variants of the new Elastic Mongoose registration\segmentation algorithm.
Performed correction for the "Calculate the Texture Gradient over the ROI only" function.  This would speed up substantially and produce less irrelevant features for certain registrations.

Invented and implemented a superior "Feature-match" function for the Elastic Flow.  It is insensitive to the ordering of the voxels in the Match Search Apperture.

Implemented a function for Volume reslicing using the Flow Map.
Images of {1,32} bit and standard interpolations are allowed.
