RNA-Seq:Main Page

This page is intended to provide participants of the RNA-Seq workshop with the pre-workshop information. For detailed information about the PMACS HPC go to our main page

Basic information

The RNA-Seq workshop is a day long workshop with the intent of showing participants how to use specific tools commonly used for RNA-Seq analysis. The workshop is of the hands-on kind where participants will have access to prepackaged code and a few sample datasets. All the exercises will be done in a demo environment that closely resembles the live PMACS HPC environment. Familiarity with working at the UNIX command line is a requirement as all the work will be done from the command line. Participants will need to bring their laptops to the workshop in order to connect to the demo environment.

Connecting to the demo environment

Secure shell (ssh) is the only supported method of connecting to the demo environment. The login machine name is demohpc.pmacs.upenn.edu. All participant will need to use Public keys to access the demo environment. Below are instructions on how to create Public-Private keys on GNU/Linux, Mac OSX and Windows systems.

Setup information for GNU/Linux and Mac OSX Users

Summary of tasks:

• Verify that you haven't already generated a Public-Priviate keypair (look inside the .ssh directory in your home area)
• If don't have keys, open a terminal and run the ssh-keygen command and follow the on-screen instructions refer picture below.
• If you do have keys, copy the id_rsa.pub key to your desktop as username-id_rsa.pub where username is your PennKey username
• Email this file as an attachment to pmacshpc@med.upenn.edu (please don't paste the contents of the file in the email).
• Do not delete either the Public or Private key till after the workshop

Example

Setup information for Windows Users

Summary of steps

• Verify that you haven't already generated a Public-Priviate keypair (if you haven't used keys before, its safe to assume you don't have a key pair already)
• If you haven't installed PuTTY (the full installer), you can download and install it from here
• Once installed, PuttyGen should be used to generate and save a PuTTy compatible Public-Private keypair
• PuTTY will be configured to use the generated keypair
• Install WinSCP for file transfer. WinSCP can be downloaded from here
• Import the PuTTY compatible keys and profile into WinSCP
• Test the connection
• Email only the Public key as an attachment to pmacshpc@med.upenn.edu (please don't paste the contents of the file in the email).
• Do not delete either the Public or the Private key till after the workshop
