How To Fix trnascan-1.4: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu trnascan-1.4 is provided by trnascan-se package.

trnascan-se is:

tRNAscan-SE identifies 99-100% of transfer RNA genes in DNA sequence while giving less than one false positive per 15 gigabases. Two previously described tRNA detection programs are used as fast, first-pass prefilters to identify candidate tRNAs, which are then analyzed by a highly selective tRNA covariance model. This work represents a practical application of RNA covariance models, which are general, probabilistic secondary structure profiles based on stochastic context-free grammars. tRNAscan-SE searches at ~ 30 000 bp/s. Additional extensions to tRNAscan-SE detect unusual tRNA homologues such as selenocysteine tRNAs, tRNA-derived repetitive elements and tRNA pseudogenes.

To fix this problem, we can install more using the command below.

sudo apt-get -y install trnascan-se

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install trnascan-se.

sudo apt -y install trnascan-se

Or if you have aptitude installed you can use the following command.

sudo aptitude install trnascan-se
