Study workflow

Neurology follows a left-to-right research flow. You can revisit earlier steps at any time; cohort views depend on uploaded datasets with assigned group labels.

Create study → Upload datasets → Run pipelines → Assign groups → Cohort analysis → Interpret / Runs

Dashboard — area home

The neurology dashboard (/areas/neurology/dashboard) shows recent studies and links to create a new study.

Readiness signal: at least one study with one uploaded dataset and one completed pipeline run.

Study home — project overview

The study page (/areas/neurology/studies/{id}) is your project hub:

  • Upload dataset — connectivity matrix, EEG, or fMRI file
  • Datasets list — open any dataset workspace
  • Subjects — imported cohort metadata (when present)
  • Cohort analysis — available when datasets have group labels
  • Runs — run history table for the study (status, pipeline type, timestamps)

Dataset workspace — analyze and explore

Each dataset opens at /areas/neurology/studies/{id}/datasets/{dsid}. Available pipelines depend on modality:

ModalityTypical sequence
Connectivity matrixGraph metrics → visualize → (cohort) NBS
EEGPreprocess EEG → EEG features → graph metrics on connectivity → microstates / TFR / source localize
fMRIBIDS validate → functional connectivity → dynamic FC → graph metrics

See Dataset workspace.

Cohort analysis — group comparison

Navigate to Cohort analysis (/areas/neurology/studies/{id}/cohort):

  1. Assign group labels to connectivity matrix datasets
  2. Run Batch graph metrics across the cohort
  3. Launch NBS when two or more groups exist
  4. Compare group-level graph metric summaries
  5. Interpret cohort or NBS results

See Subjects and cohorts.

Runs — history and reporting

The runs page (/areas/neurology/studies/{id}/runs) lists every pipeline run for the study with status, pipeline type, and timestamps, and lets you delete a run. /areas/neurology/studies/{id}/report redirects to the shared, cross-area report composer, where you can pull neurology plots (alongside other areas) into one document.

See Runs and reproducibility.
