- Dose distribution to view can be seleced from CERR menubar located at the top. Dose --> .
- Dose display can be turned-off by selectine View --> Dose
- Dose display for an individual view can be selected by right-clicking on that view and then setting the desired doseSet.
- Dose transparency can be adjusted by moving the scan-dose slider located next to the left-panel.
- Dose display ranges can be adjusted by setting the colorbar options. These can be set by (i) double-clicking the colorbar (ii) dragging the triangles at the edges of the colorbar or (iii) selecting View -> Colorbar options to manually enter colorbar ranges as shown below.
Dose distributions are stored in planC cell array and can be accessed as follows:
global planC
indexS = planC{end};
doseNum = 2;
planC{indexS.dose}(doseNum)

Notice that the fieldnames are similar to ones used in RTOG specification. Some of the important fields are:
- '.doseArray' - stores the volumetric dose data
- '.transM' - stores the 4x4 rigid-transformation matrix. If this field in empty, then the associated scan's transformation matrix is used
- '.doseUID' - stores the unique identifier for this dose distribution. Note that this fields gets modified (or should be modified) whenever user changes any data associated with this dose.
The coordinates of dose grid can be obtained by using a CERR function as follows:
[xDoseVals, yDoseVals, zDoseVals] = getDoseXYZVals(planC{indexS.dose}(doseNum))
%two methods to get dose3D from planC
%method one
dose3M = getDoseArray(doseNum,planC);
%method2
doseArray=planC{indexS.dose}(doseNum).doseArray;
