Participant Library

The Participant Library renames participants and sets their order across all plots. Renaming changes only the displayed label; the original source name is preserved.

Opening the library

1. Select a plot to open its Settings Pane.
2. In the Participant or Participant group section, click Edit participants….

Editing participants

Each participant is a row showing its original name and an editable Displayed name. Drag the grip handle to reorder; the order sets how participants appear in every plot. Two buttons sit above the list:

• Sort — Order by original or displayed name, ascending or descending. Sorting uses natural ordering, so Participant_2 comes before Participant_10.
• Bulk actions — Opens Rename items… for pattern-based renaming.

Pattern renaming

For systematic renames across many participants, use Bulk actions → Rename items…. The flyout finds a regular expression in the displayed names and replaces every match:

1. Enter a Pattern (regex). The status line shows how many names match.
2. Enter Replace with text (leave empty to delete the matched part).
3. Click Replace.

The wildcard buttons append common tokens to the pattern: \d+ (any number), \s (any space), [A-Za-z] (any letter), and . (any character).

Examples:

• Strip a prefix: pattern Participant, replace with P.
• Remove a file extension: pattern \.tsv, replace with empty.
• Drop a recording prefix: pattern Recording\d+\s, replace with empty — turns Recording34 P20 into P20.

The engine uses standard JavaScript regular expressions, so an external LLM can help you craft a pattern from example strings.
