Useq on Helix

USeq is a collection of software tools for for both low and high level analysis of next generation, ultra high throughput signature sequencing data from the Solexa, SOLiD, and 454 platforms. Initial emphasis: chIP-seq and RNA-Seq with FDR estimations. USeq is under continuous development at the Huntsman Cancer Institute in the Utah Bioinformatics Shared Resource Center.

 

Programs location

/usr/local/useq/

The environment for USeq can be set up with the 'module load useq' command. This will also set up the following environment variables:
$USEQ - points to the USeq applications area
$USEQDOCS - points to the USeq documentation

 

Command-line usage
$ java -jar -Xmx#G $USEQ/Appchoice
where # is the number of GB of RAM required.

For example, to run the USeq program ChIPSeq using 8 GB of memory, you would type:

java -jar -Xmx8G $USEQ/ChIPSeq

 

To Run GUI Interface

First log in to Helix with an Xwindows connection

The first time you run the USeq GUI, you will need to create a directory called /home/username/.GWrap and link the USeq applications and documentation as in the example below:

[user@helix ~]$ cd /data/YourUserID

[user@helix ~]$ module load useq

[user@helix ~]$ mkdir ~/.GWrap
[user@helix ~]$ ln -s $USEQ ~/.GWrap/Apps
[user@helix ~]$ ln -s $USEQDOCS ~/.GWrap/Documentation

[user@helix ~]$ java -jar $USEQ/GWrap_GUI_ClickMe.jar
