== Introduction ==
 +
This Amazon demo runs through the GotCloud SNP and INDEL calling pipelines.
 +
 +
The data used for this demo is originally from our sequencing workshop demos. We also have alignment and structural variation demos.
 +

#After logging into the Amazon node as the ubuntu user, you should by default be in the ubuntu home directory: <code>/home/ubuntu</code>
 +
## You can check this by doing:
 +
##:<pre>pwd</pre>
 +
##* This should output: <code>/home/ubuntu</code>
 +
## Take a look at the contents of the ubuntu user home directory
 +
##: <pre>ls</pre>
 +
##* This should output be 2 directories, <code>example<code> and <code>gotcloud</code>
 +
##** The <code>example</code> directory contains the files for this demo
 +
##** The <code>gotcloud</code> directory contains the gotcloud programs and pre-compiled source

# Look at the example input files:

#:# <code>bam.list</code> contains the list of BAM files per sample
 +
#:# <code>bams</code> is a subdirectory containing the BAM files for this demo
 +
#:# <code>test.bed</code> contains the region we want to process in this demo
 +
#:#* To make the demo run faster, we only want to process a small region of chromosome 22. This file tells GotCloud the region.  The region we are using is the APOL1 region

#:#:[[File:BedContents.png|400px]]

#:# <code>test.conf</code> contains the settings we want GotCloud to use for this run
 +
#:#:[[File:ConfContents.png|400px]]
 +
#:#:* For the demo, we want to tell GotCloud:
 +
#:#:*# The list of bams to use: <code>BAM_LIST = example/bam.list</code>
 +
#:#:*# The region to process rather than the whole genome: <code>UNIFORM_TARGET_BED = example/test.bed</code>
 +
#:#:*# The chromosomes to process.  The default chromosomes are 1-22 & X, but we only want to process chromosome 22: <code>CHRS = 22</code>
