Expanded the Atlas->ROI conversion function.  Tested on 174 ROI atlas.
Some performance issues have to be addressed with such high number of ROIs.


New Layer control dialog Added "Up\Down layer"
Enabled the Transparency-Slider functionality inside the new Layer Control Dialog box.

New Layer Control dialog box:

Added the "Active voxel layer" info dialog box and the GoTo (to Advance and Select Active layer) function.

Cursor hovering over the active layer with Real values now displays  "Real= ...value"
Implemented the ABT subtests for the DDC\Alpha model, new IVIM, IVIM-segmented models with the new parameters.


Implemented the ABT subtests for the DDC\Alpha model, new IVIM, IVIM-segmented models with the new parameters.


Added new Dynamic Model:  "DDC Stretched Exponential fit S = S0*(exp(-b*ADC)^alpha)"

Tested on the standard ABT dataset identical to ADC:
DDC fit:  DDC=0.0016, alpha=0.34, Residual=2.03


For comparison, we performed the ADC fit on the same data:
ADC fit:  ADC=0.001152, Residual=12

Corresponding Alpha-map processed over the ROI

1. Renamed the "MainMenu>VROI" ->  "MainMenu>Vector".
2.  Duplicated the "Rasterize Vector Entity" button of the main toolbar
under the "Main Menu>Vector>Rasterize".
3. Removed Rasterize items from "MainMenu>Trace"

IVIM {Basic,Segmented} models:  implemented new parameters "Dp*f" and "Dt*f" available to the user.
RAW   *.time file format:  implemented a support of variable naming convention when the index of the separate timepoint could contain arbitrary number of leading zeroes.

Build 217 is released.
ANALYZE with the negative value:  implemented the dialog box that show the loading options when the negative values are detected in the ANALYZE file.  This replaces several separate dialog boxes used in earlier versions.
