opencga.sh is the officially recommended command line tool for users. It implements most of the functionality with many different commands and subcommands. These commands are a one-to-one mapping of Resources from REST web services and subcommands are mapping to end-points. All the operations that can be performed using the command line internally creates one or several REST calls, so access to REST machine/cluster is required.
In the following URL, "samples" is the resource and "search" is the endpoint:
http://bioinfo.hpc.cam.ac.uk/opencga-demo/webservices/rest/v1/samples/search
the corresponding command in the command line is :
./opencga.sh samples |
and the corresponding subcommand is :
./opencga.sh samples search |
Executing ./opencga.sh will return the list of all available commands with a description for each of them as shown below:
Catalog commands: users User commands projects Project commands studies Study commands files Files commands jobs Jobs commands individuals Individuals commands samples Samples commands variables Variable set commands cohorts Cohorts commands tools Tools commands panels Panels commands Analysis commands: alignments Implement several tools for the genomic alignment analysis variant Variant commands |
The list of sample subcommands can be retrieved by simply executing the "samples" command without any argument as show below:
./opencga.sh samples Usage: opencga.sh samples <subcommand> [options] Subcommands: create Create a sample load Load samples from a pedigree file info Get samples information search Search samples update Update sample delete Delete the selected sample group-by Group samples individuals Get the individuals of a list of samples. acl Return the acl of the resource acl-update Update the permissions set for a member ... |
Generally, unless we are pointing to a public OpenCGA installation, users will first need to log in using the "users login" command line. Once the user has successfully logged in, a session file will be generated in their home folder:
~/.opencga/session.json |
This session file contains the following information:
This makes easier for users to login only once and execute any number of commands till the session token is expired. Please note down, session expiration is set by OpenCGA server independently from client. Once token is expired, user have to login again and can perform desired operations as normal.
{ "host" : "http://localhost:8080/opencga", "version" : "v2", "user" : "user1", "token" : "eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ1c2VyMSIsImF1ZCI6Ik9wZW5DR0EgdXNlcnMiLCJpYXQiOjE1NzQxNTcyODIsImV4cCI6MTU3NDE2MDg4Mn0.aMvD28oR_W5ZjWXuVpBXBGVHOEby-lAl7pb8oxOSXxE", "login" : "20191119095437", "expirationTime" : "20191119105436", "studies" : [ "user1@default:study1", "user1@default:study2" ] } |
where:
Authenticating is only necessary the first time. Users will have time to execute any other command line without the need to provide any more credentials until the stored token expires. Please note down that the token expiration time is set by the main OpenCGA installation. Once this token has expired, users will need to log back in again to keep working with the command line.
