Browsing the Genome Using Genome Browsers to Visualize and Mine Data
2
Genome Browsers Software designed to enable a user to access and display sequence data Software designed to enable a user to access and display sequence data Provide a visual correlation for different types of information Provide a visual correlation for different types of information Organize large amounts of genome sequence data Organize large amounts of genome sequence data
3
Several Different Genome Browsers Common features: Common features: Coordinate system is based on the build Coordinate system is based on the build Zoom in and out Zoom in and out Gene features aligned to genome Gene features aligned to genome Major Differences: Major Differences: Each Browser has a very different look and feel Each Browser has a very different look and feel Navigating through the information Navigating through the information

Main Genome Browser Repositories Ensembl Ensembl NCBI (Entrez) - BLAST NCBI (Entrez) - BLAST UCSC - BLAT UCSC - BLAT Ensembl, NCBI, and UCSC use the same human genome assembly that is generated by NCBI but release timing is different between sites Ensembl, NCBI, and UCSC use the same human genome assembly that is generated by NCBI but release timing is different between sites

UCSC Vertebrates, Deuterostomes, Insects, Nematodes, Yeast Vertebrates, Deuterostomes, Insects, Nematodes, Yeast Entry into genome sequence via BLAT Entry into genome sequence via BLAT Table Browser Table Browser Creation of PDF Creation of PDF Provides access to all the data produced by the project, and to the software used to analyze and present it Provides access to all the data produced by the project, and to the software used to analyze and present it Site produces and maintains annotation tracks Site produces and maintains annotation tracks

Aligned Annotation Tracks Genomic data: known genes, predicted genes, ESTs, mRNAs, CpG islands, assembly gaps and coverage, chromosomal bands, mouse homologies, and more Genomic data: known genes, predicted genes, ESTs, mRNAs, CpG islands, assembly gaps and coverage, chromosomal bands, mouse homologies, and more Annotation tracks are both computed at UCSC from publicly available sequence data and provided by collaborators Annotation tracks are both computed at UCSC from publicly available sequence data and provided by collaborators Users can also add their own custom tracks to the browser Users can also add their own custom tracks to the browser
