Each field in an assay design is associated with a set of properties of that field. This topic outlines the options available for formatting values of each data type.

Type Specific Formatting Options

Each type has specific options for formatting values, outlined here. In addition, fields of all types have name and linking options and most include validation options, described in the common topic: Field Editor.

Text/Multi-Line Text Options

  • Text Options/Multi-line Text Field Options Options: Maximum Text Length. Sets the maximum character count for the field. Options are:
    • Unlimited
    • No longer than X characters: provide a value in the box. The default is 4000.
  • Name and Linking Options
  • Validation Options: Regular expression validators.

Boolean Options

  • Boolean Field Options: Format for Boolean Values: Use boolean formatting to specify the text to show when a value is true and false. Text can optionally be shown for null values. For example, "Yes;No;Blank" would output "Yes" if the value is true, "No" if false, and "Blank" for a null value.

Integer/Decimal Options

Date Time Options

File/Attachment Options

Sources, samples, and assay designs (run and batch fields) support including file attachments, known in different structures as either File or Attachment fields.

  • Source Types use Attachment
  • Sample Types use File
  • Assay Designs allow File fields in batch and run field sections

Both field types offer:

In practice, these field types are very similar: both can accept files like PDF documents or images. The contents of these fields will display as thumbnails, open in a larger panel when clicked, and include a download option.
