Mapping between Pfam families and SCOP domain families. An instance of a SCOP domain (s_i, i = 1, ..., 5) on its member sequence is represented by a white rectangle while that of a Pfam domain (f_j, j = 2, ..., 6) is represented by a black rectangle. Striped rectangles represent their overlap. Location information is used to map a Pfam family and a SCOP domain family. Each Pfam-A family and each SCOP domain family is treated as a set of member protein sequences. The mapping process finds overlapped regions of the two types of domains on their shared member protein sequences. The overlapped regions represent where the two types of domain definitions agree.
