Workflow Guide

Build a first workflow

  1. Open Workflows and select New Workflow.
  2. Choose a template or Blank Workflow.
  3. Select an existing dataset or a completed run as the source.
  4. Use Find compatible steps. Recommendations come from manifest-declared artifact types; incompatible pipelines are not offered.
  5. Add and configure one step at a time, then save the workflow.
  6. Review Planned execution before pressing Run workflow.

Execution locations

  • Local OK runs locally by default.
  • Slow locally / Cloud recommended can transition to a configured cloud workspace when the planner determines a handoff is appropriate.
  • Completed local nodes are not rerun after handoff.

Example: BET to FLIRT

Use a completed dcm2niix run exposing nifti_raw as the source. Add FSL BET, then add FSL FLIRT from BET's nifti_skull_stripped output. BET runs locally. With a cloud workspace configured, FLIRT enters the handoff-required state. Select the workspace and press Continue in Cloud.

The workflow history records node location, run IDs, parameters, lineage, transfer state, errors, and result synchronization. A failed handoff can be retried; the idempotency key prevents a duplicate workflow execution.
