Notebook

RNArtistCore demo¶

If you haven't used one of these notebooks before, they're basically web pages in which you can write, edit, and run live code. They're meant to encourage experimentation, so don't feel nervous. Just try running a few cells and see what happens!.

Some tips:

Code cells have boxes around them. When you hover over them an icon appears.
To run a code cell either click the icon, or click on the cell and then hit Shift+Enter. The Shift+Enter combo will also move you to the next cell, so it's a quick way to work through the notebook.
While a cell is running a * appears in the square brackets next to the cell. Once the cell has finished running the asterix will be replaced with a number.
In most cases you'll want to start from the top of notebook and work your way down running each cell in turn. Later cells might depend on the results of earlier ones.
To edit a code cell, just click on it and type stuff. Remember to run the cell once you've finished editing.

Your environment¶

RNArtistCore is installed and configured in the directory ~/RNArtistCore
The RNAVIEW algorithm is installed and configured in the directory ~/RNAVIEW
