Command line tools

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

Note: the @jbrowse/cli may not do all types of operations, some use cases may best be handled by creating your own tools to manipulate a config.json by hand or by using a script file.

A simple script that does not use @jbrowse/cli at all may just look like this

const config = JSON.parse(fs.readFileSync('config.json', 'utf8'))
// do something with config.tracks, config.assemblies, etc.
fs.writeFileSync('config.json', JSON.stringify(config, null, 2))

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

jbrowse add-assembly SEQUENCE

Add an assembly to a JBrowse 2 configuration

USAGE
$ jbrowse add-assembly SEQUENCE

ARGUMENTS
SEQUENCE
sequence file or URL

If TYPE is indexedFasta or bgzipFasta, the index file defaults to <location>.fai
and can be optionally specified with --faiLocation
If TYPE is bgzipFasta, the gzip index file defaults to <location>.gzi and can be
optionally specified with --gziLocation

OPTIONS
-a, --alias=alias
An alias for the assembly name (e.g. "hg38" if the name of the assembly is "GRCh38");
can be specified multiple times

-f, --force
Equivalent to `--skipCheck --overwrite`

-h, --help
show CLI help

-l, --load=copy|symlink|move|inPlace
Required flag when using a local file. Choose how to manage the data directory. Copy, symlink, or move the data
directory to the JBrowse directory. Or use inPlace to modify the config without doing any file operations

-n, --name=name
Name of the assembly; if not specified, will be guessed using the sequence file name

-t, --type=indexedFasta|bgzipFasta|twoBit|chromSizes|custom

can optionally specify --faiLocation

bgzipFasta A block-gzipped and indexed FASTA (e.g. .fa.gz or .fasta.gz) file;
can optionally specify --faiLocation and/or --gziLocation

twoBit A twoBit (e.g. .2bit) file

chromSizes A chromosome sizes (e.g. .chrom.sizes) file

custom Either a JSON file location or inline JSON that defines a custom
sequence adapter; must provide --name if using inline JSON

--displayName=displayName
The display name to specify for the assembly, e.g. "Homo sapiens (hg38)" while the name can be a shorter identifier
like "hg38"

--faiLocation=faiLocation

--gziLocation=gziLocation
[default: <fastaLocation>.gzi] FASTA gzip index file or URL

--out=out

--overwrite
Overwrite existing assembly if one with the same name exists

--refNameAliases=refNameAliases
Reference sequence name aliases file or URL; assumed to be a tab-separated aliases
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

--refNameColors=refNameColors
A comma-separated list of color strings for the reference sequence names; will cycle
through colors if there are fewer colors than sequences

--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.
Creates ./config.json if nonexistent

EXAMPLES
# add assembly to installation in current directory. assumes .fai file also exists, and copies GRCh38.fa and
GRCh38.fa.fai to current directory
$ jbrowse add-assembly GRCh38.fa --load copy

# add assembly to a specific jb2 installation path using --out, and copies the .fa and .fa.fai file to /path/to/jb2
$ jbrowse add-assembly GRCh38.fa --out /path/to/jb2/ --load copy

# force indexedFasta for add-assembly without relying on file extension
$ jbrowse add-assembly GRCh38.xyz --type indexedFasta --load copy

# add displayName for an assembly
$ jbrowse add-assembly myFile.fa.gz --name hg38 --displayName "Homo sapiens (hg38)"

# use chrom.sizes file for assembly instead of a fasta file
$ jbrowse add-assembly GRCh38.chrom.sizes --load inPlace

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

# add assembly from a 2bit file, also note pointing direct to a URL so no --load flag needed
$ jbrowse add-assembly https://example.com/data/sample.2bit

# add a bgzip indexed fasta inferred by fa.gz extension. assumes .fa.gz.gzi and .fa.gz.fai files also exists
