At the end of each year I have a look at the website analytics to see which items were the most popular.
Over the year there were 60,000 unique visitors with 25% visiting the site on multiple occasions. The US provided 30% of the visitors and the UK 10% with Germany, Canada and Japan around 5%. As might be expected 60% of the visitors were using a Mac, but 25% of the visitors were Windows users and 10% iOS. Looking at the last month's Mac visitors, 53% were using Mac OS X 10.13, 25% 10.12 and 12% 10.11.
Safari and Chrome (each 41%) were the most used web browsers with the once dominant Internet Explorer down at 2%.
The most viewed blog pages in 2017 were
- Installing Molden
- ChemBioDraw and Word 15
- Mac OSX installer for Coot
- Scientific keyboards for iOS
- Tools for Mac Fortran Programmers
The most popular web pages were (other than the main page)
- Fortran on a Mac
- Cheminformatics on a Mac
- Data Analysis Application on a Mac
- Hints and Tutorials
- Reference Management
The continued popularity of the Fortran on a Mac web page is interesting, I'm not a big Fortran user but if anyone knows of items that could be added to the page I'd be delighted to hear about them. I've done a couple of updates to the Cheminformatics on a Mac page and I think I'll need to add a section on Bioconda in the future.
Interestingly the Scientific Applications under High Sierra page was of only transient popularity. It seem this update to Mac OSX was relatively benign with very few issues.
2017 also saw the 2000th download of iBabel, iBabel is a GUI (graphical user interface) for the open source cheminformatics toolkit OpenBabel. It also provides an interface to a variety of tools built using OpenBabel and a molecule viewer. I'm planning to do an update to iBabel to take advantage of some of the updates to OpenBabel but if you have any suggestions I'd happy to see if I can include them.
2017 also saw the migration of the website from http to https, a change that went pretty seamlessly with only a couple of minor glitches.
The Twitter feed is increasing in popularity with 390 followers. The most popular tweets were
The RSS feed still has around 100 followers
I just noticed that the latest version of iBabel has been downloaded over 1000 times, this is fantastic news and it certainly allows me to justify the effort put into creating the application.
I’m occasionally asked about the best way to install OpenBabel and I usually refer people to the page I wrote on installing cheminformatics tools on a Mac, this gives instructions on how to install a wide variety of cheminformatics toolkits and applications.
If you only want to install Openbabel then the best way is to use Homebrew.
Homebrew is a package manager for Mac OSX that installs packages in it’s own directory then symlinks the files to /usr/local. To install Homebrew you first need to have access to the command line tools for Xcode, the easiest way to do this is to download Xcode from the Mac Appstore
- Start Xcode on the Mac.
- Choose Preferences from the Xcode menu.
- In the General panel, click Downloads.
- On the Downloads window, choose the Components tab.
- Click the Install button next to Command Line Tools. You are asked for your Apple Developer login during the install process.
Or You can download the Xcode command line tools directly from the developer portal as a .dmg file. https://developer.apple.com/downloads/index.action. On the "Downloads for Apple Developers" list, select the Command Line Tools entry that you want.
To install Homebrew type this command in the Terminal
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
The 'brew doctor' command checks everything is fine. e.g. it will warn if the developer tools are missing, and if there are unexpected items in /usr/local/bin and /usr/local/lib that may clash and might need to be deleted.
It is a good idea to first update the package list
To install a range of cheminformatics packages we can use a custom “tap” created by Matt
brew tap mcs07/cheminformatics
Then to specifically install Openbabel use
brew install mcs07/cheminformatics/open-babel
To check OpenBabel is working type this in a Terminal window:
obabel -:'C1=CC=CC=C1F' -ocan Fc1ccccc1 1 molecule converted
I just noticed that the latest version of iBabel has now been downloaded over 700 times since it was released at the start of the year.
iBabel started out as an AppleScript Studio application designed as a front-end to OpenBabel DOI, this was updated several times and is now an ApplescriptObjC application built with Xcode. As well as acting as a front-end to OpenBabel it also provided a front-end to tools built on OpenBabel and a molecule viewer.
I just noticed that iBabel has now been downloaded over 500 times since the start of the year. I'm surprised and delighted that it has proved so popular.

The latest version of iBabel has now been downloaded over 400 times since it was released in January.

I thought I'd have a look at the number of downloads of iBabel there have been since I announced the latest release last month. So far there have been over 250 downloads and there seems to be a steady stream of downloads as shown in the plot below.

As well as acting as a front-end to OpenBabel it also provided a front-end to tools built on OpenBabel and a molecule viewer using a selection of java applets and plugins via an embedded web view.
Now things have settled down a bit I've restarted work on iBabel and an update is now available.
I've transitioned most of the calls to babel over to obabel the differences are highlighted here and replaced the calls to the tools based built on OpenBabel with the new corresponding calls to obabel.
I’ve been slowly updating iBabel.
There are now separate versions for Mac OS X 10.7.x and 10.8.x
More details on the iBabel3 page.
The SVG support in Openbabel has undergone significant improvements due to the brilliant efforts of Noel O’Boyle and Chris Morley in particular the ability to colour a substructure within a molecule. This requires installation of the development version of OpenBabel at present.
I’ve added a movie to show it in action.
It can be downloaded from here (24MB), this version requires Mac OS X 10.6 or higher and OpenBabel 2.3
Much will seem familiar to previous users of iBabel and the screenshots of the old version give a good overview of the capabilities, whilst the images below highlight a few of the new features.
The “Add title and index” option appends a title (default is Mol, but you can edit this in the adjacent text box) and an index number to multi-molecular files, e.g. Mol 1, Mol 2, Mol 3 etc. This is essential if you want to search files displayed in the “Viewer” since you need a unique identifier for each structure. In many cases the molecules will already have a molecule id.
Another new feature with OpenBabel 2.3 is the ability to generate 2D and 3D coordinates.
Perhaps the biggest changes have come with the “Viewer”, by storing the table data in an array we can use some of the cool ObjC functions such as the continuously updating selection count and the live searching of the “Name” text field. To import records identify the input file using the input button and then click the “Import” button.
The buttons highlighted in green allow the user to delete the highlighted row, delete all the “Selected” rows or clear all records completely. The selection can be modified using the buttons highlighted in pale blue.
For the other viewers, JMOL/JChemPaint are in the application bundle. ChemBioDraw needs to be in the Application folder but only works on some machines (something to do with only supporting 32-bit which I think we will have to wait for CambridgeSoft to address). Because of Java security issues Marvin has to be in the same file structure as the htm page, I think you only need to put an alias to Marvin in the Macintosh HD:Public folder or User:Public folder. the 2D and 3D radio buttons allow you to choose an appropriate display.
It also support JME as the editor but you need to get a copy from Peter Ertl directly and put it in the Public folder.
The PChem button pulls structures from PubChem, this can either be a single structure of a list (here is an example caslist.txt you can download to try).
As you can see the list contains a mixture of systematic names, trivial names, drug names and CAS numbers but the smart people at PubChem sort all that out nicely.
The result is two files on your output.smi which contains the successful searches and NoStructure.txt which contains cases where no structure was found. You can then import the file to view the structures.
I’d be delighted to hear of any bugs (honest) any suggestions for how iBabel might be improved.
