How To Fix gfapy-mergelinear: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu gfapy-mergelinear is provided by python3-gfapy package.

python3-gfapy is:

The Graphical Fragment Assembly (GFA) are formats for the representation of sequence graphs, including assembly, variation and splicing graphs. Two versions of GFA have been defined (GFA1 and GFA2) and several sequence analysis programs have been adopting the formats as an interchange format, which allow the user to easily combine different sequence analysis tools.

This library implements the GFA1 and GFA2 specification. It is possible to create a Gfa object from a file in the GFA format or from scratch, to enumerate the graph elements (segments, links, containments, paths and header lines), to traverse the graph (by traversing all links outgoing from or incoming to a segment), to search for elements (e.g. which links connect two segments) and to manipulate the graph (e.g. to eliminate a link or a segment or to duplicate a segment distributing the read counts evenly on the copies).

The GFA format can be easily extended by users by defining own custom tags and record types. In Gfapy, it is easy to write extensions modules, which allow one to define custom record types and datatypes for the parsing and validation of custom fields. The custom lines can be connected, using references, to each other and to lines of the standard record types.

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

sudo apt-get -y install python3-gfapy
