name
chaos: chaotic analysis of scan data

synopsis
chaos(data: in, xyin: out, output: out)

files
data:  data from the scan program

xyin:  data rearranged for chaotic analysis plot.  The file
format is ready for input to xyplo.

output: messages to the user

description
A "classical" test for chaos in a system is to transform the series:
x1, x2, x3, x4, x5, ...
Into a set of pairs of coordinates:
(x1,x2)
(x2,x3)
(x3,x4)
(x4,x5)
...
If there is no relationship, then one gets a random-looking
scatter diagram.  If there is a chaotic relationship, one gets
curves.

This program uses the potential locations of binding sites found
by the scan program (and output in file 'data') as the input series.
These values are then weighted by their probability.

bugs

The program uses the coordinates reported in the data file.  Since these are
piece coordinates they are not necessarily linear (ie, 1 to n).  If
fragments have been extracted from a circular sequence, the results will
have some incorrect data.  (This is a minor bug.)
