attempt at posting was succesful.)
Announcing the release of Namot.
NAMOT(Nucleic Acid MOdeling Tool) is a tool developed at Los Alamos National
Laboratory for the structural manipulation of single or double stranded,
RNA or DNA. NAMOT uses a set of reduced co-ordinates to describe base/unit,
sugar and phosphate geometry. Detailed description of these parameters can be
found in the references listed at the bottom of this announcement.
Namot features an X11 graphics interface for display of the molecule while
modifications are being carried out. Both Motif and XView toolkit versions
exist, which should allow namot to be easily ported to most unix machines.
An article describing namot is currently in press(CABIOS,1994).
Input: PDB,Amber, or parameters
Output: Amber, PDB, or parameters, encapsulated postscript.
General: Can be used to manipulate ss or ds RNA or DNA via
reduced parameters. Which have intuitive meaning,
and allow easy manipulation of the base/unit without
Auto-adjusts: O3'-P-O5' to allow the phosphate to cross varying gaps.
Monitors distances: A simple point and click, connects two atoms with
a dashed line and displays the distances whenever
the structure is changed.
Generation of structures:
Generates the parameters for A,B,& Z. RNA/DNA, ss or ds
Can be used as a starting place.
Label BP: Displays the unit number on the right side of the
screen at the same level as the C3'
Online help: There is an extensive online help system.
Rotations: Easily accessible rotational controls.
Currently there are three versions of namot.
The original, uses the XView toolkit and basic monochrome Xlib graphics.
It does feature a WYSIWYG(What You See Is What You Get) printing
screen that produces encapsulated postscript output.
Features color graphics options, both wireframe and CPK representations.
It produces color encapsulated postscript output. A command line lets the
user set foreground/background to white or black. The user can set the mode
to mono or color(color is the default). The command line also allows the user
to query for atom position, angles, and torsional angles. The online help
for "commands" lists the specific syntax.
Same basic features as NAMOT 1.2, but uses the motif toolkit to build the
interface and has been tested on an SGI Iris Indigo.
Namot is availible over the internet via anonymous ftp.

get <which ever version you want>
Note: SGI users may need to use "nlist" and not "ls" to list files.
NAMOT 1. and NAMOT 1.2 have been tested on:
Sun SparcStation 1+ running SunOS 4.1.3
Sun SparcStation LX running SunOS 2,3
Sun SparcClassic running SunOS 2,2
NAMOT 1.2s has been tested on
SGI Iris Indigo
