====== With Hábrók HPC ======

Hábrók is the high performance cluster (HPC) of the University of Groningen maintained by the CIT. In order store your data in the long-term and also archive it, you can easily transfer your data from Hábrók to your preferred RDMS environment. Since Hábrók is a Linux OS, ''iCommands'' are the most efficient way of transfering your data, working with metada and perform other tasks. For that purpose, ''iCommands'' are already installed on Hábrók. 

===== Accessing the RDMS =====

First connect to your Hábrók environment with your preferred SSH client. In order to use the ''iCommands'' for the first time, you just need to create an iRODS configuration file called ''irods_environment.json'' and place it in this location in your home directory: ''~/.irods/''. 

Under your home directory you will first create the hidden ''.irods/'' dot folder:
<code>
$ mkdir ~/.irods
</code>

Check if it is created:

Proceed with creating and configuring your ''irods_environment.json'' environment file as explained [[rdms:access:linux:icommands| iCommands]] section. The content should look like this:

{{:rdms:access:inkedmobaxterm_screenshot4b.png?500| }}

Now you are ready to initilaze the RDMS connection:

Please refer to the [[rdms:access:linux:icommands| iCommands]] section for further information on the configuration and various use cases of the ''iCommands''.
