18.2 Variable Number Tandem Repeats
If your experiments involve the use of microsatellites, VNTRs, or other
repeated elements, you can calculate the number of times a repeated element
occurs in a band.
Note: You must define the standards in the image before you can use this
function (see Chapter 15).
To calculate the VNTRs on your gel image, select VNTR Calculations from the
Analysis menu. (You can also select the VNTR Quick Guide from the Help
menu for guidance on analyzing gels with VNTRs.)
The Tandem Repeat Calculation dialog box will open.
Fig. 18-3. Tandem Repeat Calculations dialog box.
At the top of the dialog box is the equation used to calculate the number of
times an element is repeated in a band.
The band size is determined by the position of the band on the gel image.
