Operate set

This protocol includes several functionalities to modify any Scipion Set inside the project. It handles the internal SQLite representation to modify the set object. The user must define a reference attribute of the items which will determine the function of the protocol:

  • Unique: Keeps only one of the elements which have the referent attribute repeated.

  • Union: Merges two sets of the same type. The user can still perform the Unique operation after that.

  • Intersection: Keeps only the intersection of several sets, using the reference attribute.

  • Difference: Keeps the elements of the first set that are not repeated in the second set

  • Filter: Filters the set based on a filter attribute value and a filter operation the user can specify. Keeps only the elements that pass the filter.

  • Remove columns*: Remove a column or attribute from a Set object.

  • Ranking: Sorts the elements of a Set based on the filter column and keeps only those elements above/below a defined threshold.

These operations have some shared functionalities with “edit set” and “filter set” protocols from scipion-em. The user is free to choose among them.
