iRODS Cloudbrowser

The iRODS cloudbrowser is an application to access and download data sets that are stored in iRODS. 
It is a browser-based application that allows you to navigate through iRODS collections for which you have sufficient autorisation level. 


Before you start!

In order to use the DataHub infrastructure, make sure that you are connected to the UM- or MUMC-network. Either physically or via VPN.

Step 1 - Open the portal

Point your browser to https://datahub.mumc.maastrichtuniversity.nl/
Use the menu on the right side to login with your UM-credentials.

Don't forget to check the mark with the I'm not a robot Captcha.

 

Step 2 - Generate an iRODS password

After loggin in, you should be able to click the Browse data item in the menu at the left side. 

 

 

 

 


 

 

 

 

 

A box appears that contains your username and password. 

 

Top tip!

The buttons on the right immediately copy the contents of the box to your clipboard.

 

 

Now click on the link Open the iRODS cloud browser. This will open a new tab. 

 

 



Navigate to this new tab and enter the user name and password that you've just copied from the box and press Log in.

 

 

 

 

 

 





This will open the cloud browser and list an overview of the projects that you have been authorized for. 
































WebDAV

WebDAV provides another method of retrieving files that are stored on the DataHub infrastructure. The WebDAV protocol can be used with many different software tools. 



Use in Windows Explorer

There is a known limitation in the default WebDAV driver for Windows. The maximum filesize is set to 50 MB and can be expanded to about 4 GB using a registry hack.

More information on how to change this setting can be found on the Microsoft Support website.
Be aware that changing the Windows registry is risky and if you decide to do so, it is on your own risk!

Instead, for transferring large files, we recommend to use the Cyberduck client (described below).

Linux

There are several ways to access WebDAV in Linux. We recommend the following two ways.

  1. Mount WebDAV through davfs2
  2. Download a collection directly through wget

There are advantages and disadvantages to both methods. Using wget you will download the entire collection directly and fast to your local share.

davfs2 will make all files of a collection accessible without downloading all. Furthermore it caches files that were opened before speeding up repeated access. This can be a benefit in certain applications. But can be a drawback when many big files need to be downloaded.

davfs2
# Make sure the package davfs2 has been installed
sudo mount -t davfs https://webdav.prod.rit.unimaas.nl /path/to/mount
wget
/usr/bin/wget \
    --mirror \   
    --no-host-directories \
    --no-parent \
    --reject 'index.*' \
    --user <user>@maastrichtuniversity.nl \
    --ask-password \
