SECTION I: HIGH-SCORING SEQUENCES
- Each of the following 9 sequences has E-value less than 10.
- The E-value of a sequence is the expected number of sequences
in a random database of the same size that would match the motifs as
well as the sequence does and is equal to the combined p-value of the
sequence times the number of sequences in the database.
- The combined p-value of a sequence measures the strength of the
match of the sequence to all the motifs and is calculated by
- finding the score of the single best match of each motif
to the sequence (best matches may overlap),
- calculating the sequence p-value of each score,
- forming the product of the p-values,
- taking the p-value of the product.
- The sequence p-value of a score is defined as the
probability of a random sequence of the same length containing
some match with as good or better a score.
- The score for the match of a position in a sequence to a motif
is computed by by summing the appropriate entry from each column of
the position-dependent scoring matrix that represents the motif.
- Sequences shorter than one or more of the motifs are skipped.
- The table is sorted by increasing E-value.

SECTION II: MOTIF DIAGRAMS
- The ordering and spacing of all non-overlapping motif occurrences
are shown for each high-scoring sequence listed in Section I.
- A motif occurrence is defined as a position in the sequence whose
match to the motif has POSITION p-value less than 0.0001.
- The POSITION p-value of a match is the probability of
a single random subsequence of the length of the motif
scoring at least as well as the observed match.
- For each sequence, all motif occurrences are shown unless there
are overlaps. In that case, a motif occurrence is shown only if its
p-value is less than the product of the p-values of the other
(lower-numbered) motif occurrences that it overlaps.
- The table also shows the E-value of each sequence.
- Spacers and motif occurences are indicated by
- Spacers and motif occurences are indicated by
- Spacers and motif occurences are indicated by
- occurrence of motif `n' with p-value less than 0.0001.
- Sequences longer than 1000 are not shown to scale and are indicated by thicker lines.

SECTION III: ANNOTATED SEQUENCES
- The positions and p-values of the non-overlapping motif occurrences
are shown above the actual sequence for each of the high-scoring
sequences from Section I.
- A motif occurrence is defined as a position in the sequence whose
match to the motif has POSITION p-value less than 0.0001 as
defined in Section II.
- For each sequence, the first line specifies the name of the sequence.
- The second (and possibly more) lines give a description of the
sequence.
- Following the description line(s) is a line giving the length,
combined p-value, and E-value of the sequence as defined in Section I.
- The next line reproduces the motif diagram from Section II.
- The entire sequence is printed on the following lines.
- Motif occurrences are indicated directly above their positions in the
sequence on lines showing
- the motif number of the occurrence,
- the position p-value of the occurrence,
- the best possible match to the motif, and
- columns whose match to the motif has a positive score (indicated
by a plus sign).
