Subject: AMBER: DNA Helicoïdal Plots over time

Dear colleagues,

I've put on my web site a little tutorial and some programs to plot DNA
parameters over time. The full description is available at :
http://www.steletch.org/spip.php?article32

I've tried to explain the whole process, but basically the main tool
(dnaplots.pl) uses pre-filtered data extracted from individual Curves
analysis for getting a full plot over time for the defined parameter.
For instance, you'll easily get 23 pages of parameters using this
procedure (namely alpha, beta, gamma, delta, ... but also intra and
inter base paris parameters). The final plots are generated with XmGrace
so it is easy to used in an interactive mode after the first shot to
tweak parameters to your convenience.

The script is written in perl and can be adjusted to get more parameters
(most of the time, it is just as easy as adding a description in one list).

This setup has been successfully used for more than 4 years by me and
some colleagues so i tried to place a clear description of the working
procedure on the web page for others to benefit from this work.

Feel free to ask if you need further input, and try to look inside the
scripts (as recommended on the web page) in case you'll have some doubts
about parameters.

Hoping this will help you analyse faster your DNA trajectories,

Stéphane Téletchéa
