Command line tools

This document covers the CLI tools. Note: for @jbrowse/img static export tool, see https://www.npmjs.com/package/@jbrowse/img

Installation​

The command line tools can be installed globally using npm as follows

$ npm install -g @jbrowse/cli

A CLI tool called jbrowse should then be available in the path. You can test your installation with

$ jbrowse --version

It is also possible to do one-off executions using npx, e.g.

npx @jbrowse/cli create myfolder

It is likely preferable in most cases to install the tools globally with npm install @jbrowse/cli -g however

Commands​

      file unless --refNameAliasesType is specified

  --refNameAliasesType=aliases|custom
      Type of aliases defined by --refNameAliases; if "custom", --refNameAliases is either
      a JSON file location or inline JSON that defines a custom sequence adapter

  --skipCheck
      Don't check whether or not the sequence file or URL exists or if you are in a JBrowse directory

  --target=target
      path to config file in JB2 installation directory to write out to.

  $ jbrowse add-assembly GRCh38.chrom.sizes --load inPlace

  # add assembly from preconfigured json file, expert option
  $ jbrowse add-assembly GRCh38.config.json --load copy
