The Define Sequence Variable tool, located in the Sequences section of the Toolkit panel, allows you to define a variable to represent any sequence expression such as a file, sequence text, another variable or a function.

  • In the Define Sequence Variable area, type the desired variable into the text box. Legal characters in a variable name are A-Z, a-z, 0-9, and _ (underscore).
  • This dialog requires you to select a sequence source. See Write to Results File for information on using the four buttons: File, Sequence Text, Variable and Function.
