edwin van der trial software / shareware for mac

ChemDoodle is a fully functional chemical drawing application that works on every operating system including Linux, and works well! In addition to being multiplatform, ChemDoodle also natively reads and writes many common file formats including ChemDraws CDX and CDXML. You can write ChemDraw files for submitting journal manuscripts or share these files with your rich friends who purchased ChemDraw. No longer do you need to worry if your colleages are using compatible applications or operating systems.
Main features:
- A professional program for professional scientists.
ChemDoodle doesnt just look good, it also works well. ChemDoodle allows you to easily produce any chemical figure imaginable. All objects (atoms, bonds and shapes) are easily created and can be associated with various properties to specify their appearance. ChemDoodle also comes with a number of preset chemical document settings files, such as ACS Document 1996 and Helvetica Chimica Acta, or you may create your own. ChemDoodle also has advanced systems for loading and saving images, creating and displaying text, as well the ability to read and write important chemical file formats. And ChemDoodles functionality is only rivaled by its ease of use; it allows you to manipulate all of your items with efficient menu items or quick mouse clicks.
- Widgets - many applications for the price of one!
One of the great things about ChemDoodle is that its not just a program for creating chemical structures or molecule drawings. It is a 2D chemical environment where anything chemistry can be incorporated. ChemDoodles widgets are a great example of this freedom. These mini-applications perform various unique tasks such as interfacing with databases, generating and interpreting SMILES strings, and simulating multiplets. The output from these widgets can be easily dragged right onto your document. We are always looking to add more widgets, so you may be pleasantly surprised after updating ChemDoodle, to see a new widget that appears for you to play with!
- A variety of native file formats.
In addition to ChemDoodles own format (ICL) and chemical document settings format (CDS), ChemDoodle can flawlessly read and write ChemDraws CDX and CDXML, MDL MOLFiles and SDFiles, and chemical markup language (CML). If journals do not accept ChemDoodles ICL format or any of the vector image formats provided, just save your document as a ChemDraw file and submit that as well. All mutually inclusive objects, including shapes and images, can be saved with almost all properties preserved. This story at iChemLabs describes the reading and writing of ChemDraw files in more detail. You may also want to use structures created in ChemDoodle with other chemical applications. ChemDoodle fully supports MDLs formats, which have become the standard chemical file formats, and almost every chemical application will be able to load them. A wide range of native formats allows for ease in using ChemDoodle for any task.
