# GeneNetwork
This repository contains the current source code for GeneNetwork (GN)
(https://www.genenetwork.org/ (version 2). GN2 is a Web
2.0-style framework that includes data and computational tools for online genetics and genomic analysis of
many different populations and many types of molecular, cellular, and physiological data.
The system is used by scientists and clinicians in the field of precision health care and systems genetics.
GN and its predecessors have been in operation since Jan 1994, making it one of the longest-lived web services in biomedical research (https://en.wikipedia.org/wiki/GeneNetwork, and see a partial list of publications using GN and its predecessor, WebQTL (https://genenetwork.org/references/).
## Install
The recommended installation is with GNU Guix which allows you to
deploy GN2 and dependencies as a self contained unit on any machine.
The database can be run separately as well as the source tree (for
developers). See the [installation docs](doc/README.org).
## Configuration
GeneNetwork2 comes with a [default configuration file](./etc/default_settings.py)
which can be used as a starting point.
The recommended way to deal with the configurations is to **copy** this default configuration file to a location outside of the repository, say,
```sh
.../genenetwork2$ cp etc/default_settings.py "${HOME}/configurations/gn2.py"
```
then change the appropriate values in the new file. You can then pass in the new
file as the configuration file when launching the application,
```sh
.../genenetwork2$ bin/genenetwork "${HOME}/configurations/gn2.py" <command-to-run>
```
The other option is to override the configurations in `etc/default_settings.py`
by setting the configuration you want to override as an environment variable e.g.
to override the `SQL_URI` value, you could do something like:
```sh
.../genenetwork2$ env SQL_URI="mysql://<user>:<passwd>@<host>:<port>/<db_name>" \
bin/genenetwork "${HOME}/configurations/gn2.py" <command-to-run>
```
replacing the placeholders in the angle brackets with appropriate values.
For a detailed breakdown of the configuration variables and their use, see the
[configuration documentation](doc/configurations.org)
## Run
Once having installed GN2 it can be run through a browser
interface
```sh
genenetwork2
```
A quick example is
```sh
env GN2_PROFILE=~/opt/gn-latest SERVER_PORT=5300 \
GENENETWORK_FILES=~/data/gn2_data/ \
GN_PROXY_URL="http://localhost:8080"\
GN3_LOCAL_URL="http://localhost:8081"\
./bin/genenetwork2 ./etc/default_settings.py -gunicorn-dev
```
For full examples (you may need to set a number of environment
variables), including running scripts and a Python REPL, also see the
startup script [./bin/genenetwork2](https://github.com/genenetwork/genenetwork2/blob/testing/bin/genenetwork2).
Also mariadb and redis need to be running, see
[INSTALL](./doc/README.org).
## Development
It may be useful to pull in the GN3 python modules locally. For this
use `GN3_PYTHONPATH` environment that gets injected in
the ./bin/genenetwork2 startup.
## Testing
To have tests pass, the redis and mariadb instance should be running, because of
asserts sprinkled in the code base.
Right now, the only tests running in CI are unittests. Please make
sure the existing unittests are green when submitting a PR.
From the root directory of the repository, you can run the tests with something
like:
```sh
env GN_PROFILE=~/opt/gn-latest SERVER_PORT=5300 \
SQL_URI=<uri-to-override-the-default> \
./bin/genenetwork2 ./etc/default_settings.py \
-c -m unittest -v
```
In the case where you use the default `etc/default_settings.py` configuration file, you can override any setting as demonstrated with the `SQL_URI` setting in the command above.
In order to avoid having to set up a whole host of settings every time with the `env` command, you could copy the `etc/default_settings.py` file to a new location (outside the repository is best), and pass that to `bin/genenetwork2` instead.
See
[./bin/genenetwork2](https://github.com/genenetwork/genenetwork2/blob/testing/doc/docker-container.org)
for more details.
#### Mechanical Rob
We are building 'Mechanical Rob' automated testing using Python
[requests](https://github.com/genenetwork/genenetwork2/tree/testing/test/requests)
which can be run with:
```sh
env GN2_PROFILE=~/opt/gn-latest \
./bin/genenetwork2 \
GN_PROXY_URL="http://localhost:8080" \
GN3_LOCAL_URL="http://localhost:8081 "\
./etc/default_settings.py -c \
../test/requests/test-website.py -a http://localhost:5003
```
The GN2_PROFILE is the Guix profile that contains all
dependencies. The ./bin/genenetwork2 script sets up the environment
and executes test-website.py in a Python interpreter. The -a switch
says to run all tests and the URL points to the running GN2 http
server.
#### Unit tests
To run unittests, first `cd` into the genenetwork2 directory:
```sh
# You can use the coverage tool to run the tests
# You could omit the -v which makes the output verbose
runcmd coverage run -m unittest discover -v
# Alternatively, you could run the unittests using:
runpython -m unittest discover -v
# To generate a report in wqflask/coverage_html_report/:
runcmd coverage html
```
The `runcmd` and `runpython` are shell aliases defined in the following way:
```sh
alias runpython="env GN2_PROFILE=~/opt/gn-latest TMPDIR=/tmp SERVER_PORT=5004 GENENETWORK_FILES=/gnu/data/gn2_data/ GN_PROXY_URL="http://localhost:8080" GN3_LOCAL_URL="http://localhost:8081" ./bin/genenetwork2
alias runcmd="time env GN2_PROFILE=~/opt/gn-latest TMPDIR=//tmp SERVER_PORT=5004 GENENETWORK_FILES=/gnu/data/gn2_data/ GN_PROXY_URL="http://localhost:8080" GN3_LOCAL_URL="http://localhost:8081" ./bin/genenetwork2 ./etc/default_settings.py -cli"
```
Replace some of the env variables as per your use case.
### Troubleshooting
If the menu does not pop up check your `GN2_BASE_URL`. E.g.
```
curl http://gn2-pjotr.genenetwork.org/api/v_pre1/gen_dropdown
```
check the logs. If there is ERROR 1054 (42S22): Unknown column
'InbredSet.Family' in 'field list' it may be you are trying the small
database.
## Documentation
User documentation can be found
[here](http://gn2.genenetwork.org/help). The architecture of the
software stack is described [here](./doc/Architecture.org). The
database schema is (still) shared with GN1 and currently described
[here](http://www.genenetwork.org/webqtl/main.py?FormID=schemaShowPage). Software
documentation is being expanded in the
[source code repository](https://github.com/genenetwork/genenetwork2/tree/master/doc).
## Contributing
