View: the blossom of a genome assembly


View is a plugin for the genomer tool for genome projects. This plugin can be used to generate the files required to upload a genome project. The files generated includes sequence and annotation files. Each of the possible file formats is documented with a manual page.


The following examples are taken from the Pseudomonas fluorescens R124 genome project. These examples can be run by downloading this project and running bundle install.

The following command can be used to generate a fasta file with associated metadata:

genomer view fasta                                 \
  --identifier='PRJNA68653'                        \
  --organism='Pseudomonas fluorescens'             \
  --strain='R124'                                  \
  --gcode='11'                                     \
  --topology='circular'                            \
  --isolation-source='Orthoquartzite Cave Surface' \
  --collection-date='17-Oct-2007'                  \
  --completeness='Complete'                        \

>PRJNA68653 [organism=Pseudomonas fluorescens] [strain=R124] [gcode=11] ...

The following can be used to generate an annotation table suitable for submission to GenBank using tbl2asn.

genomer view table                                        \
  --identifier=PRJNA68653                         \
  --reset_locus_numbering=52                      \
  --prefix='I1A_'                                 \
  --generate_encoded_features='gnl|BartonUAkron|' \

Add this line to your genomer projects's Gemfile:

gem 'genomer-plugin-view'

And then execute in the project directory:

$ bundle

Run the help command and the summary plugin should be available:

$ genomer help
$ genomer man view
