Background
The PhenoScape Needs Analysis Workshop was held September 17-18, 2007 at NESCent. We invited 9 scientists from the fields of morphology, development, evolution, genetics, and ichthyology to help us define what informatic tools need to exist in order to enable synthetic research that takes full advantage of the accumulated data in each of these fields. We hoped to identify driving biological questions and use cases to guide the development of our software tools and database.
Agenda
After being introduced to the project goals, the meeting participants each provided a brief chalk talk outlining their integrative research problems. The participants then split into two break-out groups, each arranged around either the developmental genetics of morphology or the evolution of morphology. At the end of the day the groups merged again to discuss the research questions arising in the breakout groups.
The second day began with three break-out groups: correlations, phylogeny, and semantics. As before, the whole group then discussed the uses cases arising in the break-out groups, and tried to identify priorities for the project.
Driving questions/use cases
The following is a bullet-point summary highlighting both research questions and software use cases produced by the discussion. Minutes from the relevant session are linked next to each point.
- Use the database to identify discrete evolutionary modules BG1
- Depends on identifying patterns of evolutionary covariation among phenotypes
- For a branch hypothesized to be under positive selection (from e.g. a molecular analysis), identify candidate phenotypes that could have been selected for BG1
- Requires mapping phenotypic changes on phylogeny, visualizing synapomorphies
- Topology can be modified and the results of modification visualized
- Use the database to help with negative information - what knowledge is missing that is required to answer a particular question? BG1
- Integrate data regarding ecologic conditions, life history, adaptation, and evolutionary time with phenotypic and genetic data to elucidate mechanisms of phenotypic change BG2
- must integrate with existing databases, literature, across biological levels
- use other factors (environment, ecology) as constraints on data presentation
- User adds own annotations using modified curator interface, compares own data with database BG2, PB
- user may also want to store media such as images and movies
- Enrichment analysis: given a list of genes, find which phenotype terms are overrepresented among them RO1
- User is notified of additions or changes to the database relevant to him/her RO1
- save user-defined queries as RSS feeds
- Capture and represent within-species variation in phenotypes and genotypes RO1
- describe polyphenism dependent on environmental factors or variable gene expression
- view population frequencies of polymorphic phenotypes
- describe phenotypic change through developmental time series
- View traits related to particular parts of anatomy - just tail, or just vertebra CB
- User view ancestral character states on tree using default reconstruction methods CB
- User downloads data in a form useful for applying their own methods of character reconstruction CB
- Find cloud of similar annotations using summary matrices CB
- traits vs traits, traits vs genes, genes vs genes
- cells would be number of branches on which the two traits change in common (traits vs traits), or number of mutants they have in common (traits vs traits, and traits vs genes), or number of traits in common (genes vs genes)
- User uses interactive tree view to select taxa for summary matrix CB
- User selects one or more regions on body plan view to view traits(genes) affecting all CB
- then map corresponding traits on tree
- User creates and edits a tree using MacClade-like interface, then visualizes character changes on tree PB
- User may want to work with data regarding mutations actually underlying evolutionary change SB
- different genetic states in different species
Requirements arising from the use cases
The uses cases present requirements for both our scientific framework/data model and our software tools (curation tools and web application).
