What is ViennaRNA, and Why Do I Need It?
ViennaRNA is a popular package for RNA secondary structure prediction and analysis. It’s a powerful tool for researchers, bioinformatics enthusiasts, and anyone working with RNA data. With ViennaRNA, you can predict RNA secondary structures, calculate free energy, and perform other fascinating tasks. However, to unlock its full potential, you need to install it correctly, which is where this guide comes in!
Before We Begin: Prerequisites and Requirements
Before we dive into the installation process, make sure you have the following requirements met:
- A Linux or macOS operating system (Windows users, don’t worry, we’ve got you covered too!)

Step 1: Install the Required Dependencies
VienaRNA relies on several dependencies to function correctly. Let’s install them one by one:
Dependency 1: Perl
sudo apt-get install perl (for Ubuntu-based systems) sudo yum install perl (for RHEL-based systems) brew install perl (for macOS with Homebrew)
Dependency 2: C compiler
sudo apt-get install build-essential (for Ubuntu-based systems) sudo yum groupinstall 'Development Tools' (for RHEL-based systems) xcode-select --install (for macOS with Xcode)
Dependency 3: ViennaRNA-specific dependencies
sudo apt-get install libssl-dev libexpat-dev (for Ubuntu-based systems) sudo yum install openssl-devel expat-devel (for RHEL-based systems) brew install openssl expat (for macOS with Homebrew)
Step 2: Download and Compile ViennaRNA
Now that our dependencies are in place, let’s download and compile ViennaRNA:
Download ViennaRNA
wget https://www.tbi.univie.ac.at/RNA/download/sourcecode/2.4.14/viennaRNA-2.4.14.tar.gz
Extract and Compile ViennaRNA
tar -xvf viennaRNA-2.4.14.tar.gz cd viennaRNA-2.4.14 ./configure --prefix=/usr/local make sudo make install
Step 3: Install the ViennaRNA Python Package
Finally, let’s install the ViennaRNA Python package using pip:
pip3 install viennarna
Troubleshooting Common Issues
Don’t panic if you encounter any issues during the installation process. Here are some common problems and their solutions:
