The arithmetic operations available in this module include addition, subtraction, multiplication, and division. The result can be log-transformed or raised to a power and can be used in further calculations if another

The module can make its calculations on a per-image basis (for example, multiplying the area occupied by a stain in the image by the total intensity in the image) or on an object-by-object basis (for example, dividing the intensity in the nucleus by the intensity in the cytoplasm for each cell).

**Image measurements:**If both input measurements are whole-image measurements, then the result will also be a whole-image measurement.**Object measurements:**Object measurements can be produced in two ways:- If both input measurements are individual object measurements, then the result will also be an object measurement. In these cases, the measurement will be associated with
*both*objects that were involved in the measurement. - If one measure is object-based and one image-based, then the result will be an object measurement.

- If both input measurements are individual object measurements, then the result will also be an object measurement. In these cases, the measurement will be associated with

Enter a name for the measurement calculated by this module.

Choose the arithmetic operation would you like to perform. *None* is useful if
you simply want to select some of the later options in the module, such as multiplying
or exponentiating your image by a constant.

Indicate whether the operand is an image or object measurement.

Choose the objects you want to measure for this operation.

Enter the category that was used to create the measurement. You
will be prompted to add additional information depending on
the type of measurement that is requested.

Enter the number by which you would like to multiply the above operand.

Enter the power by which you would like to raise the above operand.

Indicate whether the operand is an image or object measurement.

Choose the objects you want to measure for this operation.

Enter the category that was used to create the measurement. You
will be prompted to add additional information depending on
the type of measurement that is requested.

Select *Yes* if you want the log (base 10) of the result.

Enter the number by which you would like to multiply the result.

Enter the power by which you would like to raise the result.

Enter the number you like to add to the result.

Select *Yes* if you want the result to be
constrained to a lower bound.

Enter the lower bound of the result here.

Select *Yes* if you want the result to be
constrained to an upper bound.

Enter the upper bound of the result here.
