Class Method Details

.target_coordinate_for(source_coordinate_name, quadrant_index) ⇒ String

Calculate the target coordinate for a source coordinate and quadrant number

Parameters:

  • source_coordinate_name (String) —

    Location name of the well or tube. Eg. H12

  • quadrant_index (int) —

    Quadrant index 1-4 e.g. 4

Returns:

  • (String) —

    The target coordinate in the destination 384-well plate, e.g. P24
