ENH: Movement evaluation workflow and end-to-end tutorials 11-13 - #120
Conversation
Add WorkflowEvaluateMovement, which scores an inferred moving anatomy per anatomical structure (Dice, volume, surface RMSE) and writes a CSV, volume plots, and a markdown report with provenance. Add WorkflowInferMovement.process_time_series to predict one subject across a whole time series, plus TransformTools helpers to smooth scalar arrays and wrap them as ITK images so per-timepoint deformation magnitude and RMSE fields can be written out. Tutorials: - 11 (heart, lung): evaluate PhysicsNeMo inference against ground truth - 12 (heart, lung): end-to-end inference from a raw 4D image - 13: combined heart and lung motion - rename tutorial_10_duke_heart_infer_physicsnemo to *_mgn for consistency with the lung tutorial Fix ContourTools.split_labeled_surface to pass an integer array to extract_cells so a label with no cells is reported instead of raising. Tests: test_workflow_evaluate_movement, test_workflow_train_physicsnemo, and added transform_tools coverage. Repository hygiene: - stop tracking tutorials/network_weights in LFS; weights are produced by running Tutorials 2 and 9, not distributed - MANIFEST.in drops setup.py, scripts/, and bundled weights; ships AGENTS.md - CI test paths and comments follow the renamed test modules - nightly status.json is published through the nightly-status branch Docs: tutorials, architecture, quickstart, installation, testing, and API pages updated for the new workflow; new assets for tutorials 8-13; drop stale brain_vessel_modeling and lung_gated_ct CLI pages.
WalkthroughThe PR adds time-series PhysicsNeMo inference, movement evaluation, expanded heart and lung tutorials, combined motion rendering, updated documentation, packaging rules, and CI status handling. ChangesPhysicsNeMo motion workflows

Inline comments:
In @.github/workflows/ci.yml:
- Line 238: Update the test listing and local execution instructions in
tests/README.md to reference test_convert_vtk_to_usd.py instead of the stale
test_convert_vtk_to_usd_polymesh.py entry, matching the pytest target used by
CI.
In `@docs/installation.rst`:
- Around line 242-247: Update the Tutorial 13 description near the Simpleware
dependency entry to clearly state that it uses Simpleware to segment the heart,
replacing the ambiguous wording while preserving the surrounding dependency and
licensing information.
In `@docs/tutorials.rst`:
- Around line 54-58: Update the Duke-heart dependency descriptions in
docs/tutorials.rst lines 54-58 and data/Duke-Heart-4DLabelmaps/README.md lines
20-23 to state that Tutorials 4 through 12 form a nine-tutorial chain, and
clearly distinguish Tutorial 2 as a separate optional finetuning variant.
- Around line 49-52: Keep the Heart Tutorial 7 dataset mapping consistent with
tutorials/README.md: in docs/tutorials.rst lines 49-52 remove Heart Tutorial 7
from the DirLab-4DCT list; update the dataset table in docs/quickstart.rst lines
85-87, the downstream pipeline description in docs/quickstart.rst lines 310-312,
and the See Also mapping in docs/cli_scripts/download_data.rst lines 116-120 to
identify KCL-Heart-Model plus Tutorial 6 output.
In `@src/physiotwin4d/workflow_evaluate_movement.py`:
- Around line 285-286: Update the metadata construction in the evaluation
workflow to populate network_weights_created from st_birthtime when available,
falling back to st_mtime on platforms without it; leave network_weights_modified
mapped to st_mtime.
- Line 402: Update _write_volume_plot to safely handle more structures than the
eight entries in _SERIES_COLORS by cycling the color selection, while preserving
the existing color order for the first eight structures and avoiding IndexError
for subsequent indices.
- Around line 366-374: Guard the empty-results path in process before invoking
_write_csv and _write_report, since both writers require at least one row and
_write_csv currently accesses rows[0]. If scoring produces no rows, raise a
clear error or return early instead of allowing either writer to run; preserve
normal report generation when rows are present.
In `@tutorials/tutorial_10_lung_infer_physicsnemo_mgn.py`:
- Around line 131-133: Update the reference CT path construction near
reference_ct_file to define test_mode using TestTools.running_as_test() and
resolve the file through LUNG_CT_DIRLAB.input_directory(test_mode), preserving
the existing case_id and reference_phase filename.
In `@tutorials/tutorial_11_duke_heart_evaluate_physicsnemo.py`:
- Around line 140-160: Exclude the reference labelmap from gated-frame parsing
before deriving cardiac stages. In

both ground_truth_labelmaps and stages to skip reference_files while preserving
the existing reference-file validation and non-reference frame handling.
Apply the same fix in `@tutorials/tutorial_12_duke_heart_end_to_end_inference.py`
around lines 218 - 221.
In `@tutorials/tutorial_12_duke_heart_end_to_end_inference.py`:
- Around line 166-183: Move the output_dir cleanup and creation in
tutorials/tutorial_12_duke_heart_end_to_end_inference.py (lines 166-183) until
after the required-file loop and frame/reference-frame validations; make the
same change in tutorials/tutorial_12_lung_end_to_end_inference.py (lines
166-193), placing it after the required-file loop and frame/reference-phase
checks. Preserve the existing validation and directory setup behavior otherwise.
In `@tutorials/tutorial_13_heart_and_lung_motion.py`:
- Around line 206-209: Update cardiac_cycles_per_phase in the tutorial
configuration to a value whose product with n_phases is an integer, such as 0.8,
so the cardiac axis wraps seamlessly at the animation loop boundary; keep the
surrounding wrapping documentation consistent with this behavior.

Nitpick comments:
In `@tests/README.md`:
- Around line 26-32: Add a “Workflow Tests” section to the Test Categories list
in tests/README.md, documenting test_workflow_evaluate_movement.py and
test_workflow_train_physicsnemo.py with concise descriptions consistent with the
existing entries.
In `@tests/test_tutorials.py`:
- Around line 905-936: Update the affected tutorial end-to-end tests and their
_run_tutorial_script output handling so generated artifacts are stored under
./results/<test_name> rather than tutorials/output. Pass the required output
location into the tutorial scripts, then update _compare_screenshots and
artifact assertions to use that results directory consistently across all three
test sections.

720-741: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick winValidate physical geometry for every auxiliary image.
The code validates only array shape for
normal_imageandinterior_mask. It does not validateweight_imageat all. Same-sized ITK images can have different origin, spacing, or direction. The code then combines data from different physical locations and produces an incorrect displacement transform.Reject auxiliary images unless their region, origin, spacing, and direction match
field. Add a regression test with a same-sized but shifted auxiliary image.As per coding guidelines, “never silently squeeze or permute axes” and “add or update tests that reproduce invalid inputs or regressions before implementation.”

Correct the retry description.
DataDownloadTools._DownloadFile deletes its temporary file when the download fails. A retry starts a new download. It does not resume from the partial byte offset. Replace “resumes an interrupted download” with wording that states that the download restarts.
Proposed wording
- reused, so re-running resumes an interrupted download. See
+ reused, so re-running retries the download from the beginning. SeeAs per coding guidelines: “Update docstrings for every changed public method and keep claims factual.”

Remove the undocumented exterior_normal_scale claim.
exterior_normal_scale is not a parameter or implementation feature. This text makes the public API documentation incorrect.

Add WorkflowEvaluateMovement, which scores an inferred moving anatomy per anatomical structure (Dice, volume, surface RMSE) and writes a CSV, volume plots, and a markdown report with provenance.
Add WorkflowInferMovement.process_time_series to predict one subject across a whole time series, plus TransformTools helpers to smooth scalar arrays and wrap them as ITK images so per-timepoint deformation magnitude and RMSE fields can be written out.
Tutorials:
Fix ContourTools.split_labeled_surface to pass an integer array to extract_cells so a label with no cells is reported instead of raising.
Tests: test_workflow_evaluate_movement, test_workflow_train_physicsnemo, and added transform_tools coverage.
Repository hygiene:
Docs: tutorials, architecture, quickstart, installation, testing, and API pages updated for the new workflow; new assets for tutorials 8-13; drop stale brain_vessel_modeling and lung_gated_ct CLI pages.
