nextstrain view
usage: nextstrain view [options] <path>
nextstrain view --help
Visualizes a completed pathogen builds or narratives in Auspice, the Nextstrain visualization app.
<path>
may be a dataset (.json) file or narrative (.md) file to start Auspice and directly open the specified dataset or narrative in a browser. Adjacent datasets and/or narratives may also be viewable as an appropriate data directory for Auspice is automatically inferred from the file path.
<path>
may also be a directory with one of the following layouts:
<path>/
├── auspice/
│ └── *.json
└── narratives/
└── *.md
<path>/
├── auspice/
│ └── *.json
└── *.md
<path>/
├── *.json
└── narratives/
└── *.md
<path>/
├── *.json
└── *.md
Dataset and narrative files will be served, respectively, from auspice and/or narratives subdirectories under the given <path>
if the subdirectories exist. Otherwise, files will be served from the given directory <path>
itself.
If your pathogen build directory follows our conventional layout by containing an auspice directory (and optionally a narratives directory), then you can give nextstrain view
the same path as you do nextstrain build
.
Note that by convention files named README.md or group-overview.md will be ignored for the purposes of finding available narratives.
<path>
Path to a directory containing dataset JSON and/or narrative Markdown files for Auspice, or a directory containing an auspice/ and/or narratives/ directory, or a specific dataset JSON or narrative Markdown file.
--help, -h
Show a brief help message of common options and exit
--help-all
Show a full help message of all options and exit
--open
Open a web browser automatically (the default)
--no-open
Do not open a web browser automatically
--allow-remote-access
Allow other computers on the network to access the website (alias for --host=0.0.0.0)
--host <ip/hostname>
Listen on the given hostname or IP address instead of the default 127.0.0.1. You may also set the HOST
environment variable to change the default.
--port <number>
Listen on the given port instead of the default port 4000. You may also set the PORT
environment variable to change the default.
Select the Nextstrain runtime to use, if the default is not suitable.
--docker
Run commands inside a container image using Docker. (default)
--ambient
Run commands in the ambient environment, outside of any container image or managed environment.
--conda
Run commands with access to a fully-managed Conda environment.
--singularity
Run commands inside a container image using Singularity.
Options shared by all runtimes.
--env <name>[=<value>]
Set the environment variable <name>
to the value in the current environment (i.e. pass it thru) or to the given <value>
. May be specified more than once. Overrides any variables of the same name set via --envdir
. When this option or --envdir
is given, the default behaviour of automatically passing thru several "well-known" variables is disabled. The "well-known" variables are AUGUR_RECURSION_LIMIT
, AUGUR_MINIFY_JSON
, AWS_ACCESS_KEY_ID
, AWS_SECRET_ACCESS_KEY
, AWS_SESSION_TOKEN
, ID3C_URL
, ID3C_USERNAME
, ID3C_PASSWORD
, RETHINK_HOST
, and RETHINK_AUTH_KEY
. Pass those variables explicitly via --env
or --envdir
if you need them in combination with other variables.
--envdir <path>
Set environment variables from the envdir at <path>
. May be specified more than once. An envdir is a directory containing files describing environment variables. Each filename is used as the variable name. The first line of the contents of each file is used as the variable value. When this option or --env
is given, the default behaviour of automatically passing thru several "well-known" variables is disabled. See the description of --env
for more details.
These should generally be unnecessary unless you're developing Nextstrain.
--image <image>
Container image name to use for the Nextstrain runtime (default: nextstrain/base for Docker and AWS Batch, docker://nextstrain/base for Singularity)
--exec <prog>
Program to run inside the runtime
--augur <dir>
Replace the image's copy of augur with a local copy
--auspice <dir>
Replace the image's copy of auspice with a local copy
--fauna <dir>
Replace the image's copy of fauna with a local copy
--sacra <dir>
Replace the image's copy of sacra with a local copy
--docker-arg ...
Additional arguments to pass to docker run
In some contexts, it may be preferable to provide environment variables instead of command-line options:
HOST
Hostname or IP address on which to listen by default. Ignored if --host
or --allow-remote-access
is provided.
PORT
Port on which to listen by default. Ignored if --port
is provided.
