Figure 7.

Performance of (A) sequence-identification and (B) sequence-assignment for fragments selected at random from two MX ribosomal RNA models determined at a resolution of 2.8Å (PDB entry 2uub) and 3.3Å (PDB entry 6mpi). The random fragments used for sequence identification and assignment had 50 and 20 nucleic acids, respectively. The continuous curves are logistic regression estimates of a probability that an identified sequence will have at least 90% sequence identity to the target sequence.
