backtrace {segmenTier}

Back-tracing step of the segmenTier algorithm.

Description

back-tracing step: collect clustered segments from the scoring matrix S(i,c) by back-tracing the position j=k which delivered the maximal score at position i.

Usage

backtrace(S, K, multib, nextmax = FALSE, verb = TRUE)

Arguments

S

matrix S, containing the local scores

K

matrix K, containing the position k used for score maximization

multib

if multiple k produce the maximal score, take either the shortest k ("max") or the longest k ("min"); if multib is set to "skip" the next unique k will be searched

nextmax

proceed backwards while score is increasing before opening a new segment

verb
