What is genomesontheCloud ?
gotCloud is a sequence analysis pipeline Integrative Alignment, QC, Variant Calling, Phasing Seamless Requires only simple configuration files Robust ..against unexpected failures & stops Scalable ..to many thousands of genomes gotCloud also provides… A set of many useful software tools Software library (C++) for sequence analysis Briefly Talk about software tools and library included in GotCloud

GotCloud Alignment Pipeline
& QC Single Sample Many Samples GotCloud Alignment Pipeline qplot & verifyBamID bwa / mosaik dedup & recab Processed BAM (one per sample) FASTQ Raw BAM (one per sample) QC End-to-end analysis Fully automated and parallelized (with quality controls) Requires only a simple fastq list file SAMPLE_ID FASTQ1 FASTQ2 Sample1 Sm1_Run1_1.fastq.gz Sm1_Run2_1.fastq.gz Sample2 Sm2.fastq.gz . Sample3 Sm3_1.fastq.gz Sm3_2.fastq.gz

How can I use gotCloud on the Cloud?
Briefly Talk about software tools and library included in GotCloud
14
GotCloud on the Cloud Alignment & QC Variant Calling Variant Filtering Haplotyping Deep Genomes Shallow Genomes Targeted Exomes GotCloud supports for many high-computing cluster systems MOSIX SLURM Sun Grid Engine (SGE) Portable Batch System (PBS) GotCloud also supports the Amazon Cloud In 1000G low-pass genomes examples… Average cost is $20 per genome GotCloud Amazon Machine Images (AMI) available
15
GotCloud on Amazon Cloud
Alignment & QC Variant Calling Variant Filtering Haplotyping Deep Genomes Shallow Genomes Targeted Exomes Getting started… GotCloud AMI is publicly available The AMI contains example input files You can run today’s demo on your own Adding computing power for your own analysis… GotCloud AMI supports StarCluster (SGE-compatible) You can add as many nodes as you need. You will need to upload your own files to Amazon Have your data mounted or use wget/curl/lftp
