Figure 2From: The Genome Reverse Compiler: an explorative annotation toolStart site determination. Support can come from different alignments for various start sites. Alignment 1 supports s1, s2, and s3; Alignment 2: s1 and s2; Alignment 3: s1, s2, s3, and s4. Higher start scores are given to start sites that: occur closer to a supporting alignment, occur at a higher frequency, and are supported by a higher scoring alignment.Back to article page
