2. Outline of the Topics UCSC and Ensembl Genome Browser (Blat vs Blast vs Blastz vs Multiz) 挖掘数据用 Table Browser 或 BioMart 用户友好化你的数据 写自动查询程序 基因组浏览器的介绍 序列查询

3. UCSC Genome Browser Introduction Jim Kent (http://www.genome.ucsc.edu/)

4. Organization of genomic data… Genome backbone: base position number Annotation Tracks chromosome band known genes predicted genes evolutionary conservation SNPs sts sites gap locations repeated regions microarray/expression data more… Links out to more data

5. Ensembl Genome Browser Introduction http://www.ensembl.org Ewan Birney

6. 1 1 Select Clade 2 2 Select Species 3 3 Select Assembly 4 4 Position or Term 5 5 Image width 6 6 Configure track and Image 7 Submit 7 Genome Browser

7. Protein gene microRNA/snoRNA Multiz Alignment Conserved Score Get ImageGet sequence Genome Browser

8. <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< Track colors may have meaning—for example, UCSC Gene track: exon 3’ UTR 5’ UTR Intron, and direction of transcription >> Genome Browser

9. Phenotype and Disease Mapping and sequencing Gene and Gene Prediction mRNA and ESTExpression and RegulationComparative Genomics Variation and Repeats Genome Browser

10. Hide: removes a track from view Dense: the track is displayed with all features collapsed into a single line. Squish: the track is displayed with each annotation feature shown separately, but at 50% the height of full mode. Pack: the track is displayed with each annotation feature shown separately and labeled, but not necessarily displayed on a separate line. Full: the track is displayed with each annotation feature on a separate line.

19. Blat vs Blast vs Blastz vs Multiz BLAT = BLAST-like Alignment Tool Rapid searches by INDEXING the entire genome Works best with high similarity matches –Kent, WJ. Genome Res. 2002. 12:656 Choices Paste one or more sequences

21. Blastz Alignments

31. 1. Extract Intron of Protein-coding Gene In the Human Genome 2. snoRNA/microRNA Intersect with Intron Find snoRNA/microRNA located within Intron in the human genome

32. 1 Choose Human genome 2 Choose SQL Table 3 Choose Region 4 Choose Filter Extract Intron of KnownGene In the Human Genome

33. Output KnownGene as Custom Track

34. Custom Track Displaying Custom Track in the Browser

35. Choose SQL Table Intersect with snoRNA/microRNA
