Author Guide

This page provides background information for authors whose publication(s) has been curated for the Phenoscape Knowledgebase. The goal of the Phenoscape Project is to link evolutionary data to genomics using ontologies and Phenoscape is developing a curated knowledgebase of morphological characters and prototyping the approach with ostariophysan fishes, beginning with the papers that have published data matrices. Learn more about the project and the ontologies used by Phenoscape here.

How to provide feedback

Review the Excel spreadsheet for:

• Errors in character and state descriptions, taxon list, and matrix
• Comments or questions from the curator (please see Comments columns)

Please return your comments by email or in a Word or text file referencing the particular character or taxon for each comment.

Annotation of evolutionary phenotypes using Entity-Quality syntax

The morphological variation reported in systematic character data is documented in phenotype statements recorded in Entity-Quality syntax. Entities are terms taken from the anatomy ontology to represent anatomical structures and qualities are terms taken from the quality ontology to describe the variable aspect of the structure. For example, an author may describe a “rectangularly shaped supraorbital bone.” This is represented as:

E: supraorbital, Q: shape

Phenotype annotations for characters involving more than one entity require a 'related entity' (RE) in annotation:

 E: supraorbital, Q: relational structural quality, RE: antorbital

Complex characters may also require more than one phenotype statement. For example, a character state might describe: "antorbital large and sigmoid shaped." Two EQ statements are recorded:

E: antorbital, Q: size
E: antorbital, Q: shape

Additional information about EQ syntax is available here.

Phenoscape is currently annotating characters to a coarse level of entity and quality. We are using a small set of quality terms to categorize phenotype variation into broad categories which will guide future annotation and ontology development efforts. See the Guide to Character Annotation for the list of quality terms, and for further examples of how characters are annotated in Phenoscape.

Taxon Comment	Notes or questions made by a curator regarding a particular taxon
Specimens	Voucher specimen(s) from the materials list

Characters and EQ fields:

Field	Description
Character Number
Character Description	Free-text description of the character from the publication
