No use or reproduction without express written consent10 Genome Browser Gateway: start page, basic search text/ID searches Helpful search examples samples provided Use this Gateway to search by: Gene names, symbols, IDs Chromosome number: chr7, or region: chr11:1038475-1075482 Keywords: kinase, receptor See lower part of page for help with format

11. Copyright OpenHelix. No use or reproduction without express written consent11 The Genome Browser Gateway Make your Gateway choices: 1. Select Clade 2. Select genome = species: search 1 species at a time 3. Assembly: the official backbone DNA sequence 4. Position: location in the genome to examine 5. Image width: how many pixels in display window; 5000 max 6. Configure: make fonts bigger + other choices 1 45 6 3 2

17. Copyright OpenHelix. No use or reproduction without express written consent17 Visual Cues on the Genome Browser Track colors may have meaning—for example, UCSC Gene track: If there is a corresponding PDB entry = black If there is a corresponding reviewed/validated seq = dark blue If there is a non-RefSeq seq = lightest blue Tick marks; a single location (STS, SNP) For some tracks, the height of a bar is increased likelihood of an evolutionary relationship (conservation track) Intron and direction of transcription >> < exon < < << < ex 5' UTR3' UTR Alignment indications (Conservation pairs: “chain” or “net” style) Alignments = boxes, Gaps = lines

20. Copyright OpenHelix. No use or reproduction without express written consent20 Annotation Track Options Defined Hide: removes a track from view Dense: all items collapsed into a single line Squish: each item = separate line, but 50% height + packed Pack: each item separate, but efficiently stacked (full height) Full: each item on separate line

21. Copyright OpenHelix. No use or reproduction without express written consent21 Mid-page Options to Change Settings You control the views Use pulldown menus Configure options page Reset, back to defaults Start from scratch Enforce any changes (hide, full, squish…) Flip display to Genomic 3’  5’

29. Copyright OpenHelix. No use or reproduction without express written consent29 Accessing the BLAT Tool Rapid searches by INDEXING the entire genome Works best with high similarity matches See documentation and publication for details Kent, WJ. Genome Res. 2002. 12:656 BLAT = BLAST-like Alignment Tool

30. Copyright OpenHelix. No use or reproduction without express written consent30 BLAT Tool Overview: www.openhelix.com/sampleseqs.html Make choices DNA limit 25000 bases Protein limit 10000 aa 25 total sequences Paste one or more sequences Or upload submit

31. Copyright OpenHelix. No use or reproduction without express written consent31 BLAT Results with Hyperlinks Results with demo sequences, settings default; sort = Query, Score Score is a count of matches—higher number, better match Click browser to go to Genome Browser image location (next slide) Click details to see the alignment to genomic sequence (2 nd slide) sorting go to browser/viewergo to alignment detail
