Permeabilisation time and permeabilisation time unit in imaging_preparation_protocol

Wkt8 opened this issue · comments

For which schema is a change/update being suggested?
I would like to request an update to the imaging_preparation_protocol schema.

What should the change/update be?
I would like to add two new optional fields, permeabilisation_time and permeabilisation_time_unit to the imaging_preparation_protocol schema

'permeabilisation_time_unit' would be validated against the ontology module.

This update constitutes a minor change to the schema(s) it affects.

**What new field(s) need to be changed/added?

  • Field name: permeabilisation_time
  • Field description: The permeabilisation time in permeabilisation time units that the tissues were permeabilised for
  • Field type: number
  • Required: no
  • Examples: 15, 20-25
  • Guidelines: "Enter either a single value or a range of values. Indicate a range using a hyphen."

Field 2

  • Field name: permeabilisation_time_unit
  • Field description: The unit in which permeabilisation time is expressed
  • Field type: object
  • Required: no
  • Examples: 42
  • CV or enum: "module/ontology/time_unit_ontology.json",

Why is the change requested?
Data contributors need to be able to store and find permeabilisation_time as this is a key feature that they are interested in Visium experiments.
