Step 1: Configure inputs#

In Inputs:

  • add one or multiple BIDS dataset paths,

  • optionally reorder/remove datasets,

  • select global settings or enable Use per-dataset configuration.

Step 2: Set analysis profile and policies#

In Analysis profile + policies:

  • Mode: legacy, new, reuse, latest

  • Profile ID: optional or required depending on mode

  • Config policy: provided, latest_saved, fail

  • Processed subjects: skip, rerun, fail

Step 3: Optional output root#

In Output folder (optional) set Derivatives output only when outputs should be outside dataset roots.

Step 4: Configure calculation runtime#

In QA/QC calculation tab:

  • set global Calculation n_jobs,

  • optionally enable per-dataset n_jobs override,

  • use per-dataset Scan/select for subject selection.

Step 5: Execute#

  • Run Calculation: calculation only.

  • Run GQI: recompute GQI attempts from existing metrics.

  • Run ALL (calc + plotting): full orchestration (calculation then plotting).

Stop buttons abort active tasks.

Example scenarios#

Scenario A: one dataset, all subjects, new profile#

  • add dataset,

  • set mode new (optional explicit profile ID),

  • keep subjects=all,

  • click Run Calculation.

Scenario B: two datasets, different configs and subjects#

  • add datasets A and B,

  • enable per-dataset config,

  • assign each settings file,

  • use Scan/select per dataset,

  • click Run Calculation.

Scenario C: full pipeline in one action#

  • configure plotting choices in QA/QC plotting tab,

  • click Run ALL (calc + plotting).

Runtime safety behavior

When one run starts, other run buttons are disabled until completion or stop.
