Figure 2

A PAVE contig joined by n's. No ESTs in the left and right sub-contig overlap, so the two sub-contigs are joined by 50 n's, which is indicated by the green box in the consensus sequence under the position 1900. The drawing of the EST indicates quality (blue is low quality), mismatches (red) and gaps (green). What appears to be thick blue lines are ESTs with no quality values, so all bases are low quality.
