FireVoxel Builds {193,194,195} are released.
1. Volume reslicing using polynomial transforms: corrected imprecision defect due to incorrect rounding.
2. MainMenu>Volume>Smooth (and other smoothing operations): restored correct operation on the ROI.
3. Sokoloff model (Short formula): added additional user controls so the values of all parameters {K1,k2,k3} could be fixed during the optimization. User simply set k2_min = k2_max = Desired Value.
4. Sokoloff model (Long formula): added additional user controls so the values of all parameters {K1,k2,k3} could be fixed during the optimization. User simply set k2_min = k2_max = Desired Value.
5. Enabled loading of the GE-scanner diffusion dataset by providing a specialized procedure to load b-values from the private GE tags.
6. Corrected defect when FVX format file for storing the parameters of Dynamic Experiment are changed.
7. Implemented the "Blood Volume" User parameter for Sokoloff Short\Long models.
8. Loading ANALYZE file: fixed defect of incorrect truncation of signed negative numbers to 0.
9. Implemented new User- Interface-level function that produces all 6 projections of the SulciPrint3D directly from the BrainMask
10. Implemented User-level Active volume "Mirror along axis" function. This is under "MainMenu>3D Projection>Mirror along axis". Function is now working for all 3 axis {X,Y,Z}.
11. Corrected and updated the "Open TAC as 4D volume" function. This allows user to specify the *.TXT file containing the TAC.
12. Implemented basic variant of Monte-carlo simulation for all Dynamic Models in FireVoxel.
13. Implemented a new menu "Dynamic Processing" in the MainFrame part of the processing (i.e. when no volume is required to be loading).
14. Implemented the functionality for F3\F4 Roi Stats 3D\4D: when ROI is missing, function calculates stats for the ROI that covers the entire volume.
15. Dynamic Experiment framework: fixed defect in all models involving the Input Function(s).
16. Enabled that Concentration conversion parameters are remembered and then recalled between several calls to the corresponding dialog box.

Implemented basic variant of Monte-carlo simulation for all Dynamic Models in FireVoxel.
User starts with obtaining the required ROI and saving it to the file.
User starts with obtaining the required ROI and saving it to the file.
User create a 4D-volume from the specified TAC setting the level of noise (10% in this example). Then runs the chosen model over the 4D volume, where each voxel corresponds to the original TAC+ random Noise.
Resulting is the map(s) of the selected parameters (K1 in this example).
Next user is able to do some basic statistics on the specified parameter, K1 in this case.
Corrected and updated the "Open TAC as 4D volume" function. This allows user to specify the *.TXT file containing the TAC. User specifies dimensions of the resulting volume where which voxel is constructed given the specified TAC + random Noise (Noise level is specified by the User).
This functionality allows to perform Monte-Carlo modelling of the Dynamic Models.

Implemented new User- Interface-level function that produces all 6 projections of the SulciPrint3D directly from the BrainMask. There is no need to generate intermediate SulciPrint3D structure. Function is under the MainMenu>Applications>BrainPrint>Generate SulciPrint2D from BrainMask (6 projections).

Initial tests of the "Snowball" methodology for automatic fluid registrations, segmentations, and organ localization. In one scenario we would try to locate both kidneys on the volume, fully automatically, using only sparsely defined library of shapes.

Saving Active Dynamic model settings to FVX file: corrected a design flaw. Sometimes we change the number of Free and Output parameters in the models. If this model was save previously to FVX file as an Active model the current version of FireVoxel often would not be able to load such FireVoxel file and it will be lost. In the corrected version, only the warning that the Model design was changed would show but file would always be loaded.
