Traits

Overview

Data is collected in Field Book by defining different traits. Each trait layout is optimized for a specific type of data collection. The traits screen allows new traits to be defined and existing traits to be managed.

Creating a Trait

Traits can be created by pressing the large icon at the bottom right of the screen, or the same icon in the toolbar. For each format, the creation screen adjusts to indicate which fields are required. Trait names must be unique. Each trait is created by specifying a trait format, a trait name, optional details, and format-dependent fields such as min, max, and default.

Managing Traits

Once created, traits can be manipulated using the following features:

Single trait changes

Reorder an individual trait by pressing and dragging the icon on the far left of its trait line.

Copy, edit, or delete an individual trait by pressing the icon on its trait line, then selecting the desired operation from a list.

Reorder all traits by selecting Sort, then chosing your sort criterion (options include trait Name, Format, or Checked status)
Remove all traits by selecting Delete all traits, then confirming the operation.
Transfer traits in and out by selecting the Import/Export option.

Trait imports and exports are similar to field imports/exports in that they rely on files stored in a dedicated folder, or on communication with a designated server using a BrAPI (Breeding API) connection.

When using local storage, trait lists are stored as .trt files in the trait folder. Internally, .trt files store their data in a CSV format, but it is not recommended to manually edit these files.
