iRODS Access
Experiment data for omics project data is stored under a distributed iRODS server, which you can log on to with your Charité or MDC credentials. For accessing project data, membership in respective projects must be granted to you by a project owner or delegate.
For each project, sample data repository is located in the read-only
sample_data
collection. For uploading new files, you must create a landing
zone as a temporary workspace. These are placed under the landing_zones
collection. For more instructions, see the Landing Zones application under the
project you are working on.
Command Line Access (Linux)
For command line access to iRODS, you should use iRODS iCommands in your Linux shell.
On the BIH Cluster, the required packages are already installed. If you need to
access the data from elsewhere on the network, you need to install the
irods-icommands
package. See the
official installation instructions for more
information.
Note
On Ubuntu 20.04, installing iCommands is not officially supported at the time of writing. For workarounds, see this discussion.
To configure your iCommands connection, go to the iRODS Info
application. In the app, click on “Download Configuration” to receive a
configuration file archive. This archive contains the irods_environment.json
file pre-configured for your user account. A server certificate file for secure
connections is also included.
Enter the directory where you saved the downloaded archive and enter the following commands:
mkdir -p ~/.irods
unzip irods_config.zip -d ~/.irods
iinit
You will be prompted for your password, which is the same one you use to access this web site. After this, you should be successfully logged on to iRODS and can access data on the storage in your terminal.
Note
When using iput
or irsync
to upload data into the SODAR iRODS
server, you must use the -k
argument to enable checksum generation.
See iRODS documentation for iCommands reference.
WebDAV
Project iRODS data can be accessed for through WebDAV by mounting it as a network drive or browsing it in read-only mode on a web browser. Links in SODAR UI provide shortcuts to specific collections and files on the WebDAV.
