What's new in Marvin and development discussion

Contents

What’s new in Marvin?• Structure representation• Better quality graphics• Improved usability• New GUI design• Plug-ins• File IO• Future plans and discussion

Structure representation• Improvements in Markush

compound drawing (alpha)– Position variation– Repeating unit with repetition ranges

Structure representation• Coordination compounds (alpha)

– New bond type: coordinate bond• Between atom – atom:• Between atom – group of atoms:

– Connection to a group of atoms with multicenter attachment point

Structure representation• Polymer drawing (alpha)

– Source and structure-based representation of polymer types: SRU, repeating unit with repetition ranges, anypolymer, copolymer, crosslink, graft, mer, modification, monomer

• Drawing of ordered and unordered mixtures (release 4.1.2)

Structure representation

Structure representation

• Multistep reaction drawing (alpha)– Reaction scheme with any number and

layout of graphical reaction arrows

• Left and right abbreviations for abbreviated groups (release 4.1)

Better quality graphics

Better quality graphics

• Improved 2D cleaning (alpha)– Nice cleaning of big rings (built up

from hexagons) – Template based

Better quality graphics

• New graphical objects – Graphical arrow in reaction (release 4.1.8)

– Graphical brackets (alpha)

Improved usability

• Status bar with 2D/3D drawing mode selection and modified status (alpha)

• Chain drawing mode button (alpha)

Improved usability• Insertable OLE component into

MSOffice documents (alpha)

New GUI design

• Customizable menus and toolbar (alpha)

• Customizable shortcut keys (alpha)

Three ways of customization (alpha) : – Interactive– Configuration file– API

New GUI design

• Toolbar and menubar icons• Cross-platform “Java Look”

(JGoodies)• Improved User Interface design

and usability “Java Feel” (coming soon)

Plug-ins

• Tautomerization Calculator Plugin:– Generation of the major (dominant)

tautomeric forms based on predicted pKa values. (release 4.1)

– Generation of the canonic tautomeric form based on predicted pKa and an empirical rule system.  Filtering of tautomer couples. (release 4.1.9)

– Prediction of the tautomer distribution. (release 4.1.9)

Plug-ins– The length of the tautomerization path

can optionally be adjusted. (release 4.1.9)

– Takes into account the major tautomeric form in the pKa, logP, and the logD calculations. (release 4.2)

• Markush enumeration Calculator Plugin (alpha)

• Structure to name Calculator Plugin (release 4.1.7) – Traditional or IUPAC name

Plug-ins– Name generation is free when

used from Marvin GUI. – Real-time updated name display in

MarvinSketch (alpha)

File IO

• Saving of specific Marvin settings, stored in mrv with structure (alpha)

• PDB import improvements, for example multi-model proteins (release 4.1.2)

Future plans and discussion

• Basic structural IO of CDX (ChemDraw) format

• Align & distribute for molecules in MarvinSketch

• Load Templates from specified directories

• Spreadsheet-like table where different columns store different types of data

Future plans and discussion

• Name to structure• New skins for Marvin to help

chemists who are used to other programs like ChemDraw and Isis/Draw.
