CMake installation and upgrade: What worked & what didn’t?!
CMake is a widely used cross-platform build system that automates the process of compiling and linking software projects. In bioinformatics, CMake can be utilized to manage the build process of software tools and pipelines used for data analysis, algorithm implementation, and other computational tasks. However, managing the versions of CMake or upgrading it on Ubuntu (Linux) can be a trivial task for beginners. In this article, we provide methods for installing and upgrading CMake on Ubuntu.
What didn’t work!
I tried to install and upgrade my CMake from version 3.16 to 3.2x using different methods including: (If you prefer not to read this, you can jump to the next section for the installation instructions.)
- pip3 (pip3 install cmake)
It did install the latest CMake (version 3.29) but couldn’t find the location. I got errors while trying to install other software as follows:
“Command ‘cmake’ not found,”, or
“Requirement already up-to-date: cmake in /.local/lib/python3.8/site-packages (3.29.2)”
“bash: /usr/bin/cmake: No such file or directory“ - hash -r
In one of my previous posts, I mentioned about this command. However, it works only when you have correctly installed the CMake version and want to upgrade. It can’t find the new path and you get errors like:
“CMake Error: Could not find CMAKE_ROOT !!! CMake has most likely not been installed correctly. Modules directory not found in /home/user/.local/share/cmake-3.16 cmake version 3.16.3” - sudo apt install cmake
You can install CMake from the repository but you will not be able to find its location. - sudo snap install cmake
It also didn’t work for me. I got an error stating:
“Error: This revision of snap “cmake” was published using classic confinement
and thus may perform arbitrary system changes outside of the security
sandbox that snaps are usually confined to, which may put your system at
risk.If you understand and want to proceed repeat the command including
–classic.“
None of the methods mentioned above worked for me. I had to uninstall CMake and reinstall it from scratch, as demonstrated in the following section.
What worked!
Preparing system
Update and upgrade your system first.
$ sudo apt-get update
$ sudo apt-get upgrade
Uninstall the previous version of CMake.
$ pip3 uninstall cmake
Downloading CMake
Clone the GitHub directory of CMake from here or use the following command. You can download it in any directory, I am downloading it in ‘Downloads‘.
$ git clone https://github.com/Kitware/CMake.git
Installing Prerequisites
Install the build dependency package necessary for CMake installation.
$ sudo apt install build-essential libssl-dev
Installing CMake
Let’s change to the CMake directory.
$ cd CMake/
Now run the bootstrap script present in the same directory.
$ ./bootstrap
It will take a few minutes to finish. After it finishes, run the make command:
$ make
After that, install CMake,
$ sudo make install
It will take a while to finish the installation.
After that, check your installation using the following command:
$ cmake --version
It should display the latest version.

DS Visualizer is a comprehensive, free molecular modeling and visualization tool designed by BIOVIA, part of Dassault Systèmes [1]. It enables researchers to visualize and analyze complex chemical and biological data, including molecular structures, sequences, and simulations.DS Visualizer’s user-friendly interface supports various file formats and provides powerful tools for molecular editing, docking, and structure analysis. In this article, we are installing DS Visualizer on Ubuntu (Linux).

HTSlib is an open-source C library designed for handling high-throughput sequencing (HTS) data [1]. It provides the underlying functionality for manipulating various file formats commonly used in genomics, such as SAM (Sequence Alignment/Map), BAM (Binary Alignment/Map), CRAM (Compressed Reference-oriented Alignment Map), and VCF (Variant Call Format). In this article, we are installing on Ubuntu (Linux).
Molecular Dynamics (MD) simulation analysis involves interpreting the vast amounts of data generated during the simulation of molecular systems. These analyses are necessary to study the physical movements of atoms and molecules, the stability of molecular conformations, reaction mechanisms, and thermodynamic properties, among other aspects. In this article, we will give a brief overview of some widely used MD simulation analysis tools.
ProteStAr is a bioinformatics tool to compress protein structure files [1]. It compresses PDB/CIF files and supplementary PAE files. The compression is lossless. However, users are allowed to generate the lossy compression of files. In this article, we are installing ProteStar on Ubuntu.
Understanding the relationship between genes and proteins is crucial for elucidating biological processes, and disease mechanisms, and developing targeted therapies. A new tool developed by Yang et. al., [1], provides a better solution to map annotated positions and variants to protein structures automatically. 3Dmapper is a stand-alone tool based on R and Python programming languages that map annotated genomic variants or positions to protein structures [1]. In this article, we will install 3Dmapper on Ubuntu (Linux).

Free_Energy_Landscape-MD: Python package to create Free Energy Landscape using PCA from GROMACS.
In molecular dynamics (MD) simulations, a free energy landscape (FEL) serves as a crucial tool for understanding the behavior of molecules and biomolecules over time. It is difficult to understand and plot a meaningful FEL and then extract the time frames at which the plot shows minima. In this article, we introduce a new Python package (Free_Energy_Landscape-MD) to generate an FEL based on principal component analysis (PCA) from MD simulation done by GROMACS [1].
Virtual screening (VS) is a crucial aspect of bioinformatics. As you may already know, there are various tools available for this purpose, including both paid and freely accessible options such as Autodock Vina. Conducting virtual screening with Autodock Vina requires less effort than analyzing its results. However, the analysis process can be challenging due to the large number of output files generated. To address this, we offer a comprehensive Python package designed to automate the analysis of virtual screening results.

vs_interaction_analysis.py: Python script to perform post-virtual screening analysis
Analyzing the results of virtual screening (VS) performed with Autodock Vina [1] can be challenging when done manually. In earlier instances, we supplied two scripts, namely vs_analysis.py [2,3] and vs_analysis_compounds.py [4]. This time, we have developed a new Python script to simplify the analysis of VS results.
Interactive Genome Viewer (IGV) is an interactive tool to visualize genomic data [1]. In this article, we are installing IGV and tools on Ubuntu desktop.
