How To Fix Chrysalis: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu Chrysalis is provided by trinityrnaseq package.

trinityrnaseq is:

Trinity represents a novel method for the efficient and robust de novo reconstruction of transcriptomes from RNA-seq data. Trinity combines three independent software modules: Inchworm, Chrysalis, and Butterfly, applied sequentially to process large volumes of RNA-seq reads. Trinity partitions the sequence data into many individual de Bruijn graphs, each representing the transcriptional complexity at a given gene or locus, and then processes each graph independently to extract full-length splicing isoforms and to tease apart transcripts derived from paralogous genes.

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

sudo apt-get -y install trinityrnaseq

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

You can also use apt command to install trinityrnaseq.

sudo apt -y install trinityrnaseq
