You can calculate the volume of painted voxels, or mask, in an image and view the information about the volume on the Data page of the Output window.
To calculate the volume of masks
1 Open an image, and paint the voxels in a desired area of the image.
2 Follow the instructions for manually creating a mask in "Generating masks", "Segmenting Images Using Contours and Masks,"
3 Do not commit the paint, which permanently merges the paint layer with the image layer.
4 Click the Calculate Volume of Paint icon, in the Paint toolbar.
The region grow information (how many voxels or pixels are painted) and the volume of all painted voxels appear on the Data page of the Output window (Figure 9).
To view the information
1 Select the Output window.
2 Select the Data tab on the Output window to view the information. The Data page of the Output window (Figure 9) appears.

To save the information
1 Select File > Save Messages in the Output window.
The Save dialog box opens.
2 Specify a name for the messages file and select a location for storing it.
3 Click Save. The software saves the file and places it in the specified location.
