Integrating iNMR with Open Babel

iNMR can work in synergy with Open Babel, the open-source chemistry toolbox. This integration significantly expands the capabilities of iNMR, allowing it to handle a vast array of chemical file formats and automate the indexing of molecular metadata.

Key Advantages

• Universal Format Support: You can paste, into an iNMR spectrum, files in any format recognized by Open Babel (e.g., ChemDraw, Molfile, XYZ, etc.).
• Direct Paste from ChemDraw: You can simply copy a structure from ChemDraw and paste it directly onto your spectrum.
• Automatic Metadata Import: When pasting a structure, iNMR automatically imports critical information such as the SMILES string, molecular weight, and molecular formula.
• Finder Integration: Once the spectrum is saved, this metadata is visible in the macOS Finder. Just use the command File > Get Info (Cmd-I) to see the chemical details embedded in the file.
• Searchability: These details are indexed by Spotlight, enabling you to search for your spectra based on chemical formula or SMILES directly from the OS.
• Enhanced Previews: The same information is accessible to QuickLook, providing a rich preview of the document without opening the application. You can learn more about how iNMR utilizes these macOS technologies in our articles on molecular metadata and cost-effective workflows.

Installation Guide

To enable these features, you need to install Open Babel. On Windows it is a straightforward process: go to http://openbabel.org and download it. It is different with a Mac. The most efficient way to do this is via Homebrew.

1. Install Homebrew

If you don't have Homebrew installed, open the Terminal application (found in /Applications/Utilities/) and paste the following command:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Follow the on-screen instructions to complete the setup.

2. Install Open Babel

Once Homebrew is ready, installing Open Babel is a single command away. In the Terminal, type:

brew install open-babel

After the installation is complete, iNMR will automatically detect Open Babel, and you can immediately start enjoying the benefits of this integration.
