Array Group

1. To adjust the number of rows and columns in the arrays, enter new values or use the up and down arrows to incrementally increase or decrease the number of rows or columns. All of the arrays are changed.
2. Use the Expand and Contract buttons to incrementally move the spots in the arrays.
3. Click the small arrow at the right edge of the Array group to open the Advanced Array Definition dialog where you can set the spot size, spacing between the spots in the arrays, and how the spots are named. Use the grid to define each spot as either Signal, Background, or None.
