A gene is a collection of domains. The domains included in a gene need not be consecutive or of the same type. Genes and domains can be defined in the input data, and can be defined and edited in the Setup Genes and Domains dialog. Genes can be selected or unselected from an analysis. When a gene is unselected, all its domains are automatically unselected. However, a gene can be selected, with some of its domains unselected.
