4)Compose a motif.
If all of the following four conditions (1 through 4) are satisfied within the entire range
of the evaluation length, perform composition.
• Begin with the first motif. If the i’th motif and i+1’th motif are processed and
successfully composed, then compose the i+2’th motif and i+3’th motif. If the
composition is not successful, process and compose the i+1’th motif and the i+2’th
motif.
• When the last two motifs are processed and at least one pair has been composed,
repeat composition from the first motif. Repeat same process until all motifs that can
be composed have been composed.
(Condition 1: peak height)
The height of central peak P
2
should be lower than that of either peaks P
1
or P
3
preceding and succeeding the central peak.
P2 ≤ P1 or P2 ≤ P3
(Condition 2: motif height)
The motif height after composition should be higher than those of the motifs preced-
ing and succeeding the motif.

≥ T
1
and T

≥ T

(Condition 3: motif height)
The height of either the right or left motif should be less than T
r
, which is equal to
60% of T
3
, the motif height assuming that the motif group is a motif.
T1 ≤ Tr or T2 ≤ Tr
(Condition 4: motif width)
After composition, motif width AR
i
should be smaller than the upper limit of the
motif length (AM).
ARi ≤ AM , where AM is LR (upper limit of motif length)
