- SSERC CHEMICAL MODELLER
- -----------------------
-
- Arc-Chemmod is a molecular modelling software package for all Acorn
- Archimedes computers including the A3000, A3020, A4000 and A5000 machines.
- The only requirements are that 2Mbytes of RAM must be installed and the
- machine has a Riscos operating system. The program runs in mode 15 on a
- standard monitor and benefits considerably from the presence of an Arm3
- cached processor. Those with multi-sync monitors where mode switching is not
- automatic may need to adjust the manual height controls for the optimum
- screen display.
-
- The program allows building, displaying, manipulating and measuring of
- molecular models and includes molecular mechanics routines for minimising
- the steric energies of small to medium sized molecules. Several molecular
- structures can be displayed and manipulated at the same time. In this
- release of Arc-Chemmod, the total number of atoms displayable is limited to
- 500. The atom limit for energy minimsation is set at 100, as larger
- structures minimise very slowly for machines lacking arithmetic coprocessor
- hardware.
-
- The software is extremely easy to set up and use, with the mouse or
- trackerball allowing quick, unambiguous interaction with the graphics
- display. Structures can be displayed as coloured stick models, as simple
- space-filling models with covalent radii, as ball and stick models, as Van
- der Waals surface space-filling models or as dot-surface models with
- covalent radii. Stick and simple space-filled models can also be displayed
- as red-green stereo images. Most manipulations are generally carried out on
- the stick models as they are the quickest to redraw, but rotations and
- translations can be carried out on the simple space-filling representation.
- Atoms may be simply identified by their colours, with the default settings :
-
- Carbon - green
- Nitrogen - blue
- Oxygen - red
- Halogens - yellow
- Hydrogen - white
- Sulphur - magenta
- Phosphorus - magenta
- Metals - cyan
-
- The colour of any atom or molecule can be simply changed at will.
- Structures, together with colour detail, can be saved to disc for future
- work and the program includes comprehensive hard-copy facilities. Structures
- can also be saved as Drawfiles or sprites for further manipulation outwith
- the Arc-Chemmod package.
-
- If a set of structural coordinates is known e.g. from a crystal structure
- analysis, this may be entered directly from the keyboard using the Create
- New File utility.
