Introduction of galaxy and UCSC genome browser
outlines
• What’s galaxy• How to use galaxy– Upload your data– FastQC– ChIP-seq/MACS
• How to use UCSC genome browser– Load wiggle/BED files into browser tracks
About galaxy• Galaxy is an open, web-based platform for
data intensive biomedical research.Public server: http://main.g2.bx.psu.edu
More about galaxy
• A web-based computing server• Many software have been installed• You can upload your data to server• You can run installed tools to analyze your data• You can share your data to others
• You can also install your own tools (advanced feature)
Experiment (I): upload Fastq data

Experiment (III): ChIP-seq/MACS
• You need to at least one dataset: IP-ed DNA• It is preferred to have control/input DNA
• Practise to upload data.bam and control.bam into galaxy
Experiment (III): ChIP-seq/MACS
IP-ed DNA
control DNA
Experiment (III): ChIP-seq/MACS
• Many options/parameters– Choose default setting– Check to output wiggle files for IP/control data
Screenshot of results
Save both wiggle files of IP-ed and control DNA
UCSC genome browser
• A web-server to display genome information in graph
• Pre-installed annotation– Gene, repeat, others
• Custom tracks for user upload data

Experiment (IV): show ChIP-seq data in genome browser
