This feature is used to specify the character string used to separate multiple values contained within the same row in the category variable.For example, for a column of annotations like those typically provided by Affymetrix, the string /// separates distinct categories. This is seen in the figure below:The Pathway column, shown above, lists the functional pathways (metabolic and other) for a number of different gene products. Each row represents a separate gene. In those cases where a gene product functions in more than one pathway, the individual pathways are separated, or delimited, by three forward slashes (///).Note: There are blanks at the beginning and ending to properly segment the categories.
You must enclose the delimiter within double quotation marks (“”).
For example, to specify /// as the delimiter, type “ /// “ in the field. Be sure to include the blanks before and after the delimiter, within the double quotation marks, as shown below.Note: If you leave this field blank, then each row is assigned to only one category, which is the value of the Annotation Category Variable.
