Copyright OpenHelix. No use or reproduction without express written consent9 Genome Browser Gateway: start page, basic search text/ID searches Helpful search examples, suggestions below 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
10
Copyright OpenHelix. No use or reproduction without express written consent10 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

Copyright OpenHelix. No use or reproduction without express written consent15 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

No use or reproduction without express written consent16 Options for Changing Images: Upper Section Change your view or location with controls at the top Use “base” to get right down to the nucleotides Configure: to change font, window size, more… Specify a position fonts, window, more Walk left or right Zoom in Zoom out click to zoom 3x and re-center
17
Copyright OpenHelix. No use or reproduction without express written consent17 Annotation Track Display Options Some data is ON or OFF by default Links to info and/or filters Menu links to info about the tracks: content, methods You change the view with pulldown menus After making changes, REFRESH to enforce the change enforce changes enforce changes Change track view
18
Copyright OpenHelix. No use or reproduction without express written consent18 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
19
Copyright OpenHelix. No use or reproduction without express written consent19 Reset, Hide, Configure or Refresh 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’

26
Copyright OpenHelix. No use or reproduction without express written consent26 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
27
Copyright OpenHelix. No use or reproduction without express written consent27 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
28
Copyright OpenHelix. No use or reproduction without express written consent28 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
29
Copyright OpenHelix. No use or reproduction without express written consent29 BLAT Results: Browser From browser click in BLAT results A new line with Your Sequence from BLAT Search appears! Base position = “full” menu and zoomed in enough to see amino acids in 3 frame translation query
