Improving Models & Measures Why model? “Killer Applications”: Share, Search, Merge, Check, Design

The issue is not speed, but integration. Cost per 99.99% bp : Including Reagents, Personnel, Equipment/5yr, Overhead/sq.m Sub-mm scale : 1  m = femtoliter ( ) Instruments $2-50K per CPU Why improve measurements? Human genomes (6 billion) 2 = bp Immune & cancer genome changes >10 10 bp per time point RNA ends & splicing: in situ bits/mm 3 Biodiversity: Environmental & lab evolution Compact storage 10 5 now to bits/ mm 3 eventually & How ? ($1K per genome, bits/$ )

Projected costs determine when biosystems data overdetermination is feasible. In 1984, pre-HGP (  X, pBR322, etc.) 0.1bp/$, would have been $30B per human genome. In 2002, (de novo full vs. resequencing ) ABI/Perlegen/Lynx: $300M vs. $3M 10 3 bp/$ (4 log improvement) Other data I/O (e.g. video) bits/$

Why single molecules? Integration from cells/genomes/RNAs to data Geometric constraints : Who’s “in cis” on a molecule, complex, or cell. e.g. DNA Haplotypes & RNA splice-forms

Alternatively Spliced Cell Adhesion Molecule Specific variable exons are up-or-down-regulated in various cancers Controversial prospective diagnostic / prognostic marker (>1000 papers) Can full isoforms resolve controversy and/or act as superior markers? Eph4 = murine mammary epthithelial cell line Eph4bDD = stable transfection of Eph4 with MEK-1 (tumorigenic) CD44 Exon Combinatorics (Zhu & Shendure)

1. Search Signature Image for qualified ‘objects’ a. > 50 connected pixels with same signature value b. ‘solidity’ of > 0.50 c. long axis / short axis ratio < 3 OR a. > 25 connected pixels with same signature value b. ‘solidity’ of > 0.80 c. long axis / short axis ratio < Search for internal regional maxima within each object (lest two adjacent polonies with same signature get counted as one) 3. Assign centroid locations as qualified individual ‘polonies’ Trial & Error Derived Algorithm for Polony Finding
