Volume Tools
Volume tools enable you to manually quantify features on a sample image when
automated lane and band analysis is not appropriate or possible, such as in dot
blots.
You can use Volume tools to quantify the signal intensity of bands, spots, arrays,
and other image data. Define an area of interest by surrounding it with a shape. You
can choose a rectangle, circle, freehand, or lane shape by clicking the appropriate
button under the Volumes field.
