Hi there, Need help for beginner. I have a problem testing gatk-4.1.7.0. I am new to both Linux system and GATK. I am following (https://gatk.broadinstitute.org/hc/en-us/articles/360041320571--How-to-Install-all-software-packages-required-to-follow-the-GATK-Best-Practices) and was able to install BWA, SAMtools, and Picard and successfully test those. To make long story short, I downloaded gatk-4.1.7.0 (Download release :gatk-4.1.7.0.zip) using (https://github.com/broadinstitute/gatk/releases), uzipped it and placed in Desktop directory. Then, according to the guideline in Getting Started with GATK4 (https://gatk.broadinstitute.org/hc/en-us/articles/360036194592-Getting-started-with-GATK4) section 5 (Install it) I set path for gatk in .bashrc. as given below. The same thing I did for bwa and samtools. export PATH=$PATH:"/home/arjun/Desktop/gatk-4.1.7.0/gatk" Assuming that after I set path I can test gatk directly from terminal, I used command gatk --help I am getting “Command 'gatk' not found, did you mean:…” and few other lines. Note. I am using python3 version (Python 3.8.2). Guideline says “You will need Python 2.6 or greater to run the gatk wrapper script”. Also, the java version I am using is “openjdk version 1.8.0_252”. I believe this is java version 1.8 as described in guideline. Please help me to figure out the problem with installation/testing of gatk. Is the problem related to path issue. If so please help me to figure out.

The PATH should point to the directory, not to the executable. try

export PATH=$PATH:/home/arjun/Desktop/gatk-4.1.7.0

Thank you for quick response, Pierre! Now I am getting. arjun@arjun-VirtualBox:~$ gatk --help

/usr/bin/env: ‘python’: No such file or directory

Some time ago, I installed python 2.7 although I had python3 installed earlier. Now, I have both. Removing executibable from PATH also did not help. export PATH=$PATH:"/home/arjun/Desktop/gatk-4.1.7.0" But still I am assuming it has something to do with path or may be I am wrong.

Have you tried with conda? It is a package manager that will save you a lot of time, as the programs are ready to install and conda takes cares of dependencies (added a link so you can follow their installation guide).

You will need to install conda. Then you can create a new environment and install gatk as following:

1.Create a new environment

conda create -n my_new_environment

2.Activate environment and install

conda activate my_new_environment

conda install -c bioconda gatk4

I hope the answer helps! Best,

Jordi
