The ProfileGrid viewer showing the RecA protein family results. The first 3 rows of the ProfileGrid are a position ruler (Posn), a majority consensus (Major), and a template sequence (here of the E. coli RecA homolog). The remaining rows tabulate the frequency of the amino acid and gap characters at each position of the alignment. Cells are color shaded according to the frequency value (Figure 3). The top-left corner identifies the character and the frequency of the ProfileGrid cell currently selected by the cursor.
