A computed field is a schema field that automatically computes a value based on other values in your Benchling tenant. You can use computed fields to display a field from a parent entity onto the child entity, calculate the molecular weight of your protein entities, or calculate the average of all results recorded against an entity.

This article provides an overview of:

Computed Field

A computed field is a special type of field that lives on an entity schema and is automatically computed based on other values in the system. Computed fields may pull information directly from a specified field on an entity or indirectly from other linked entities within the Registry. Results can also be pulled onto an entity in a couple different formats.

Your Benchling admin must assign a formula configuration to the computed field, which informs Benchling of the data type that you would like pulled or calculated. A comprehensive list of formulas offered in Benchling have been documented in this help article.

Computed fields are specifically used in the Registry to track live data across all registered entities. Say you have a computed field on a protein that displays the resistance gene linked to its parent plasmid. If that resistance gene were edited at a later time point, the computed field would recalculate its value and display the new resistance gene.

Snapshot Fields

Users can now configure snapshot fields, a type of computed field, on Results and Workflows schemas to look up data from anything that is linked to inventory or registry items. Unlike computed fields, however, these snapshot fields are frozen in time.

Configuring Benchling to capture results at a specific point in time allows scientists to view and query this information in context with experiments, workflows, and the sample itself. Snapshot fields can be used in a multitude of ways, some of which include:

  • The ability to record results against a sample’s container: teams can now associate results with wells and containers in the Inventory.

  • Automatic data entry: scientists can automatically populate a results table with a sample’s metadata.
