12  Configuration

FLIM Playground provides an interactive configuration workflow to help users prepare their datasets that are not extracted by Data Extraction so that they fulfill the requirements.

The following sections use the iris dataset as an example: the flower_id is added to uniquely identify each row (i.e. a single flower). The other columns are: a categorical feature species, and a set of numerical features sepal_length, sepal_width, petal_length, and petal_width.

The configuration workflow in motion:

Specifically, the steps are:

Then the configuration interface will be displayed.

12.1 Analysis Profiles

✨ NEW ✨: Users can now create, save, and switch between multiple analysis profiles—each a ready-to-go configuration tailored for different datasets.

  • On the left you can select an existing profile to load.
  • In the middle you can create a new profile.
  • On the right you can delete an existing profile.

Everything described below is pertained to the current profile.

12.2 Identifiers Config

  • The dataset needs to have a unique identifier column to identify each row. In this case, flower_id is the unique identifier column. This dataset does not have a field of view column, so we leave it blank.

12.3 Categorical Feature Config

  • Add categorical columns you want FLIM Playground to recognize here. Those columns are converted to strings internally.

The default categorical feature list does not include species, so we add it manually.

12.4 Numerical Feature Config

  • Users can copy the numerical features from Excel or any text editor that opens their CSV files. The features can be separated by ,, ;, or whitespaces including newlines.

  • After hitting the ctrl/cmd + enter key, the numerical features are parsed and added to Available Features. Users can add/delete groups and drag features from the Available Features to the groups they’ve just created. Any ungrouped features are added to a group called Uncategorized Features.

12.4.1 Example

12.5 Save

  • After users finish the configuration and click the Save Configuration button, FLIM Playground saves configurations into the current profile and loads it for processing current and future datasets.

12.6 Reset

Users can reset the current profile to the default configurations.
