indana: analysis of an index
synopsis
indana(ind: in, ana: out, subind: out, indanap: in, output: out)
files
ind: an index produced by the index program. it must not be a
teaching index.
ana: a histogram of the similarities of the index along with the
mean, standard deviation and frequency distribution of the
the similarities.
subind: portions of the index selected by the parameters in indanap.
pairs (or adjacent sets) of lines of the index are printed. the
similarities of the original index are maintained. this means that
the first similarity of a pair (or set) is not a reflection of the
similarity to the line above it. the ones that are 'true'
are marked with an asterisk [*].
indanap: parameters to control indana, containing 3 lines:
1. the lowest similarity to put into subind
2. the highest similarity to put into subind
3. if the first character is 'b' then the groups of similar
sequences will be broken apart by blank lines.
description
An index is usually quite large, so it is difficult to look at by hand.
Indana allows one to select a portion of the index by various criteria.
The portion is called a "sub-index". If the original book contained a
number of highly similar oligo- nucleotides, then the histogram of
similarities will show a spike of high similarities.
