Installation
As described in the documentation, HGVA backend is powered by the OpenCGA project. The CLI is distributed with the rest of the OpenCGA code. The OpenCGA code can be cloned in your machine by executing in your terminal. Checkout the latest code (release-1.1.0 branch):
Code Block | ||||
---|---|---|---|---|
| ||||
$ git clone https://github.com/opencb/opencga.git $ git checkout v1.3.6 |
Alternatively, you can download tar.gz files with the code for the latest tags/releases of OpenCGA from:
https://github.com/opencb/opencga/releases
Once you have downloaded the code, follow the instructions at the How to Build section of the OpenCGA repository:
https://github.com/opencb/opencga
The CLI interface is accessible through the opencga.sh script:
Code Block | ||||
---|---|---|---|---|
| ||||
$ cd opencga opencga$ cd build opencga/build$ cd bin opencga/build/bin$ ./opencga.sh Program: OpenCGA (OpenCB) Version: 01.91.0-dev Git commit: a1ab0decf97556241b446d23cc596ecb5a3f997cf2dace56fcdf491efee8ebb0cb43f981e31c320e Description: Big Data platform for processing and analysing NGS data Usage: opencga.sh [-h|--help] [--version] <command> [options] Catalog Commandscommands: users User commands projects Project commands studies Study commands files FilesFile commands jobs Jobs commands individuals IndividualsIndividual commands families Family commands samples Samples commands variables Variable set commands cohorts Cohorts commands Analysis commands: alignments Implement several tools for the Toolsgenomic commandsalignment analysis panelsvariant PanelsVariant commands |
The CLI provides commands, subcommands and parameters to access its functionality. Commands of most interest for HGVA users are projects, studies, cohorts and samples. Please, find below a list of commands which can be of most interest for HGVA user. Further documentation on the OpenCGA CLI can be found at the Command Lines section of the OpenCGA documentation.
Configuration
As previously said, the CLI makes intensive use of the RESTful API. Thus, the only configuration detail needed for the CLI to work is a URL where the Web Services API is hosted. The configuration file client-configuration.yml is used for this purpose. You shall find a template of this file at the build/conf directory:
Code Block | ||||
---|---|---|---|---|
| ||||
$ ll opencga/build/conf/client-configuration.yml -rw-r--r-- 1 fjlopez fjlopez 290 Oct 24 17:49 opencga/build/conf/client-configuration.yml |
Edit this file with any text editor and set the rest → host attribute to "http://bioinfodevbioinfo.hpc.cam.ac.uk/hgva-1.0":

Examples
The CLI provides commands, subcommands and parameters to access its functionality. Commands of most interest for HGVA users are projects, studies, cohorts and samples. Please, find below a list of commands which can be of most interest for HGVA user.Getting information about
genomicvariants
Getting variant data from a given study:
You can query variants by using the variant command and query subcommand. An extensive list of filtering parameters allow great flexibility on the queries (check Swagger documentation link above). Please, check inline help provided by opencga.sh for further details. For example, get TTN variants from the Genome of the Netherlands study, which is framed within the reference_grch37 project. We will restrict studies data to those corresponding to GONL. Finally, we will also limit the number of returned results to 3:http://bioinfodev.hpc.cam.ac.uk/hgva-1.0/webservices/rest/v1/analysis/variant/query?gene=TTN&studies=GONL&limit=3
Code Block | ||
---|---|---|
| ||
./opencga.sh variant query --gene TTN --study GONL --limit 3 --of json --output-study GONL |
Getting information about projects
Getting You can use the command projects to query projects data.
For getting all metadata from a particular project :
http://bioinfodev.hpc.cam.ac.uk/hgva-1.0/webservices/rest/v1/projects/{projects}/info
you can use the info subcommand. For example, getting all metadata for the referencecancer_grch37 project:
http://bioinfodev.hpc.cam.ac.uk/hgva-1.0/webservices/rest/v1/projects/reference_grch37/info
Getting grch37 project:
Code Block | ||
---|---|---|
| ||
./opencga.sh projects info --project cancer_grch37 |
For getting all metadata from all studies associated to a particular project :
http://bioinfodev.hpc.cam.ac.uk/hgva-1.0/webservices/rest/v1/projects/{projects}/studies
yo ucan use the studies subcommand. For example, getting all studies and their metadata for the cancer_grch37 project:http://bioinfodev.hpc.cam.ac.uk/hgva-1.0/webservices/rest/v1/projects/cancer_grch37/studies
Code Block | ||
---|---|---|
| ||
./opencga.sh projects studies --project cancer_grch37 |
Getting information about studies
Get You can use the command studies to query studies data.
For getting all available studies and their metadata . Please you can use the search subcommand. For example, getting all metadata for all available studies (please note, of special interest will be here the field alias which contains the study identifier to be used as an input whenever a study must be passed as a parameter):
http://bioinfodev.hpc.cam.ac.uk/hgva-1.0/webservices/rest/v1/studies/search
For example, getting all metadata for all available studies:
