Using the electronic lab notebook eCAT as a replacement for a paper lab notebook

Posted by Rory on July 26th, 2010 @ 7:00 am

Wikipedia defines electronic lab notebook as “a software program designed to replace paper lab notebooks“.  So how can you use eCAT to replace something that looks like this?

Let’s look at this question first from the individual’s point of view and then from the lab’s point of view.  Here’s what Andreas Johansson of Lund University in Sweden says:

“I use eCAT for everything in the laboratory when I need to make a note of anything.  I use it for my experiments and my protocols.  But I also use it for things I didn’t use it for before I had an electronic lab notebook.  I use it for digital photos, so protein gels, screenshots of my HPC runs, screenshots of the small things I see during my experiment.  Before I would have just made a small note about it, now I have a photo of it.  And I also add time stamps during an experiment so I can easily see at what point I did a certain thing.

The main result is very very large quality improvements.  It also brings structure to your experiments automatically.  Since you are working with project folders you have your own experiments, and you also add protocols, and you add the data and you add whatever electronic stuff you get during the experiments to that folder.  So everything gets sorted by date and time.

And here’s what Alex Swarbrick at the Garvan Institute in Sydney, Australia says about his lab’s use of eCAT:

Everyone uses it as an electronic notebook, so they can compile the diverse collections of data that we generate as biologists, such as images and spreadsheets. We use to it to take minutes of meetings. We also use it to manage our common stocks of antibodies, plasmids and so on. Finally, perhaps the most important feature for us is the ability to link records, reagents and experiments. This allows us, for example, to connect an experimental mouse with the tube containing its tissues in the freezer, to the 6 different experiments (conducted over a year) that analysed those tissues in different ways. Managing this kind of ‘metadata’ is absolutely essential to our work, and very difficult to do without tools like eCAT.”

Of the many benefits of using eCAT as an electronic lab notebook noted by Andreas and Alex, three are worth highlighting:

  1. eCAT serves as  a ‘paper lab notebook plus’ because you can use it to record not only garden variety experimental data but also things like images and spreadsheets which can’t conveniently be entered into a paper lab notebook.
  2. eCAT allows you to manage other kinds of information such as notes from meetings, protocols and inventory, as well as experimental data, in a single, integrated environment.
  3. Unlike a paper lab notebook, which by definition is a tool for individuals, eCAT is a group tool that allows controlled  sharing of data.
