Precourse

These are steps to be completed before the workshop

You will have to have 3 different accounts to complete the labs in this course; one in SUPR to handle the two other accounts, and one each at the compute centers PDC in Stockholm and UPPMAX in Uppsala.

1 SUPR

A SUPR/NAISS account is needed to create the accounts for the computers we will be using during the course. SUPR is also the system that you will handle your own projects in if you want to use this kind of resources in your research after the course.

If you do not already have one, create an account at SUPR/NAISS. Then, Log in to SUPR/NAISS, preferably using the SWAMID (requires that you are within Swedish academia).

Before proceeding with applying for project membership and user account, we have to accept the NAISS User Agreement. Do this by clicking the Personal Information link in the left sidebar menu. The scroll down a bit until you reach the section User Agreements. If you already have accepted it the State will be a green box with the text Accepted in it. If it is anything else, click it to start the accepting process.

Tip

This is where you might run into trouble if you don’t have a SWAMID connected account. You will not be able to accept the user agreement online without it, so you will have to send in your acceptance in paper form together with a copy of your passport. This process can take a week or more, so please make sure you can accept the user agreement in good time.

2 PDC

The computing cluster Dardel at PDC will be use during the course. After making sure you have an accepted user agreement, go to the SUPR/NAISS Projects page and request membership to the project ID: naiss2025-22-143

Once you are accepted to a project, you should see that project listed under your active projects.

Finally you need to request a login account to PDC. This will be the account you use to log in to the actual computers, so it is not the same as your SUPR account. Login to SUPR and go to the Accounts page. Under the Possible Resource Account Requests heading click on Request Account at PDC button and confirm it on the next page. If it is missing from this page, it could be because you already have a login account created (only 1 account per person allowed), or that you have not yet gotten your project memberships approved.

Checking your request and approving your account requires some manual work, so you might have to wait for some time (up to a couple of working days) before the next step. When the account is ready to be created, you will receive an email to your registered email address (shown in your SUPR contact information) with information about your account. Follow the instructions you get from them to complete your account creation. The morning session on the Monday of the course will cover how to connect to PDC, a bunch of steps that might not be trivial for novice users.

3 UPPMAX

The computing cluster UPPMAX will be use as a fallback cluster, if there should be any problems at PDC. Just with the PDC accout, you need to request a login account to UPPMAX. This will be the account you use to log in to the actual computers, so it is not the same as your SUPR account or your PDC account. This requires you to already be a member of the course project, naiss2025-22-143, the same project you became a member of in the PDC section above.

Login to SUPR and go to the Accounts page. Under the Possible Resource Account Requests heading click on Request Account at UPPMAX button and confirm it on the next page. If it is missing from this page, it could be because you already have a login account created (only 1 account per person allowed), or that you have not yet gotten your project memberships approved.

Checking your request and approving your account requires some manual work, so you might have to wait for some time (up to a working day) before the next step. When the account is ready to be created, you will receive an email to your registered email address (shown in your SUPR contact information) with information on how to proceed. You will get a one-time URL that you use to get the password (within seven days) to login to the cluster with. The link is only valid for 1 visit, so write down the password you get. When that has been done, the account ready for use within 15 minutes and you can then login using your password. Once you have logged into the cluster you can change your password by typing passwd in the terminal and follow the instuctions.

Note

You will get one username & password for the account on UPPMAX, and one username and password for the account on PDC. Please keep track of both, we will tell you when to use which account during the workshop.

4 Install tools

4.1 Zoom

Note

This is is only relevant for online courses.

We will use Zoom for the online sessions. please download and install the latest version for your OS.

4.2 ThinLinc

ThinLinc allows graphical connection to UPPMAX. Download and install from https://www.cendio.com/thinlinc/download.

4.3 XQuartz

Mac users will need to download and install XQuartz for X11 forwarding. ie; to forward remotely opened windows to local machine.

4.4 IGV

Integrative Genomics Viewer (IGV) is useful in inspecting genomic data in BAM files. IGV is available on the cluster, but it might be very slow over X11. IGV is also available through ThinLinc but it depends on the reliability of ThinLinc and the network connection. Having a local installation of IGV gives you the freedom to download the BAM files and inspect them locally.

4.5 MobaXterm

If you are on a Windows system, and you want to open graphical applications from the terminal, we recommend MobaXterm. It is recommended that you INSTALL the program and not use the portable version. MobaXterm also has an integrated SFTP file browser.

4.6 Filezilla*

When you need to transfer data between the remote cluster and your computer, you can use the tools SCP or SFTP through the terminal. Windows users can use the SFTP browser available with MobaXterm. If you prefer a GUI to upload and download files from the remote cluster, we recommend installing FileZilla.

* Optional

4.7 Eduroam

Note

This is is only relevant for on-site courses.

Please make sure you have a working Eduroam wifi connection setup before the course, since we will only have wifi internet access in the computer room where we have the course. The instructions on how to get it working could differ university to university, so please refere to you home university’s instructions on how to do that. Try searching for “eduroam” and your home university, e.g. eduroam uppsala university, to find it.

Tip

If you want to get a primer on using the terminal, you can get started with the following Tutorial One at this link Unix tutorial for beginners. You can use https://scilifelab.github.io/courses/ngsintro/common/emu/ (or this mirror) to try the commands in the tutorial, so that you don’t mess up any real world system.
