Report on PAG 2016

• strong emphasis on high throughput phenotyping, machine learning is hot right now
• data standardization, field scale measurements
• Utilization of ontologies for data annotation
• everyone wants specialized ontologies for THEIR data, not something predefined

- we need to demonstrate how ontologies are useful.

Planteome Collaborators Workshop Monday Jan 11th

- http://planteome.org/outreach/workshops/PAG_2016

• Goals of the Meeting:
  • Introduce the Planteome project and launch Planteome 1.0 beta
  • Provide an update on the progress of the collaboration with the Crop Ontology to map crop-specific trait dictionaries to the Reference Trait Ontology
  • Provide a summary report and overview of the Planteome Curators Workshop, held Nov 2015 in Corvallis, OR
  • Engage Planteome collaborators and the plant genomics community by demonstrating use cases of data annotation for rice, cassava and lentils
  • Seek engagement of the plant genomics community through tools and applications to integrate into your workflow

• Who attended?

- 29 attendees (link to spreadsheet: Participants list CO-Planteome Meeting PAG 2016)

- Representatives from: CG centers (IITA, CIP, CIMMYT, IRRI) and Bioversity; INRA, IRD, LIRMM, USDA-ARS databases (SoyBase, MaizeGDB, GDR, PeanutBase, LegumeInfo), EBI, Transplant, ELIXIR Consortium, Rothamsted Research.

Comments and feedback

• People are concerned about the GAF2 format, but hopefully it will be expanding to more than 16 columns- modification of the GAF2 format
  • we will develop standards for conversion to GAF2

Data download functionality on the browser needs to be refined

• PJ: Suggest to have the column headings disaplyed- that would help people

• figure out what format people want to download data in, allow for download in this format
  • GeneBanks use the MCPD format (?)
  • Need a few use-cases for questions that researchers will be trying to answer

Update on browsers

• Main Planteome website: http://planteome.org/
  • drupal front pages and AmiGO2 browser serving ontologies and annotation data

• Development site: http://dev.planteome.org/amigo
  • Currently just ontology files but can also load annotations on there to test
  • loads nightly with all the ontologies

Issues being sorted out:

• Many of our relations are not being recognized and displayed in AmiGO 2.0 (https://github.com/Planteome/planteome-ontology-browsers/issues/20)
  • only showing up- is_a, part_of and occurs_in; this is an issues for the Gene Ontology as well
  • Gene Ontology tracker:

• Synonym scopes are not being displayed- all the broad, narrow, related and exact synonyms are being lumped together- (https://github.com/Planteome/planteome-ontology-browsers/issues/17)

From MAL:

• The CO terms are showing up as subclasses, but they get confused with other things that are subclasses
  • Perhaps they should be 'taxonomic equivalents' AND subclasses; perhaps you can have double-relationships??? (Suggestion from BS)
  • Perhaps color coding in combination with changing CO_### to the correct name

• Visualization: Need a better way to view trees.

- Choices now are OLS-vis, or the static .png display
