Job: Particle Sets Tool

Split a particle group into subsets or compare two groups.

Description

Split a particle group into subsets or compare two groups.

Inputs

• particles_A: Particles

  • With only this group $A$ specified, choose the split action to split the data into multiple batches

• particles_B: Particles (optional)

  • With both groups $A$ and $B$ , choose the intersect action to compute set operations on the two groups, including (i) intersection $A ∩ B$ and differences (ii) $A - B$ and (iii) $B - A$.

Common Parameters

• Action

  • With only one particle input group, choose split to split the data into multiple batches

  • With both particle input groups, choose intersect to compute the set intersection and difference between the two groups.

  • if intersect is selected, a new parameter is available: Field to Intersect

    • uid: use the uid field to intersect the two inputs

    • path : use the particle's path and image index to intersect the two inputs.

      • The token used to intersect particles will be a concatenation of the particle's path from blob/path and its index from blob/idx.

• Split num. batches: With the split action, how many batches to split the particles into

• Split batch size: With the split action, the number of items to place into each split batch that is output. Additional items will be output as a separate remainder output. If the value is None, the items will be split into equal sized batches.

• Split randomize: With the split action, randomize the particles to add to each batch

Outputs

• Split mode:

  • split_X (multiple outputs): With the split action, batches of the resulting particles

  • remainder: With the split action, particles left out of split_X batches due to the specified batch size and number of batches

• Intersect mode:

  • intersect and intersect_B outputs: With the intersect action, these contain the result of $A ∩ B$

    • For the intersect output, all of the result groups in common from set A and B (e.g. blob, ctf, alignments3D, etc.) and passthrough groups will be copied from set A

    • For the intersect_B output, all of the result and passthrough groups will be copied from set B

  • A_minus_B: With the intersect action, set difference $A - B$

  • B_minus_A: With the intersect action, set difference$B - A$

Example outputs when only one input particle set is provided compared to two sets.
