.bashrc setup

If you already have a .bashrc set up, make a backup copy first. You can restore your original login script after class is over.

Code Block

language	bash

cd
cp .bashrc .bashrc.beforeNGSTools

Copy and configure the login profile for this class

Code Block

language	bash

cd
cp /work2/projects/BioITeam/projects/courses/Core_NGS_Tools/tacc/bashrc.corengs.stampede2  .bashrc
chmod 600 .bashrc

# or, using your symlink
cd
cp ~/CoreNGS/tacc/bashrc.corengs.stampede2  .bashrc
chmod 600 .bashrc

Source it to make it active (if this doesn't work, log off then log back in):

Start an idev session

To start an a 3-hour idev (interactive development) session:

Code Block

language	bash
title	Start an idev session

idev -p normal -m 120 -N 1 -n 2468 -A UT-2015-05-18 --reservation=CCBBBIO_DATA_week_1

Tip
You can tell you're in a idev session because the hostname command will return a compute node name (e.g. nid00438 c401-041.stampede2.tacc.utexas.edu) instead of a login node name (e.g. login5. login2.stampede2.tacc.utexas.edu).

The n idev session will terminate when the requested time has expired, or you use the exit command.
