Inline comments:
In @.dockerignore:
- Around line 13-14: Add an explicit .dockerignore allowlist entry for
utils/lung_bundle.py alongside the existing utils rules so the Dockerfile COPY
using that source remains valid; retain the Dockerfile COPY block at Dockerfile
lines 81-84 unchanged.
In `@docker/brev-deploy.sh`:
- Around line 40-56: Update the download-lung-bundles.sh invocation in the
deployment flow to honor the existing use_sudo decision, using the same Docker
access fallback as docker_cmd while preserving required environment and
arguments. Apply this consistently to both download-step occurrences, without
changing the existing behavior when direct Docker access is available.
In `@docs/installation.rst`:
- Around line 113-124: Update the Method 1 PyPI installation instructions to
state that the [all] extra requires an R580-series driver, and add a separate
command using the CUDA 12.6 extra plus the required optional features for
R560/R565 users. Keep the existing CUDA-specific installation guidance
consistent with these commands.
In `@docs/viewing_meshes.rst`:
- Around line 67-72: Update the viewing meshes documentation near the VTP
example to clarify that VTP overlays are static and the --fps option applies
only to USD input; ensure the example does not imply that --fps 3 can be used
with the shown VTP command.
In `@pyproject.toml`:
- Around line 129-141: The published cuda12 installation instructions must
select the CUDA 12.6 package index instead of relying on the project-only
pytorch-cu126 mapping. Update the cuda12 dependency/install guidance in
docs/faq.rst and the associated install command to use an explicit CUDA index,
or switch to a source-checkout command that reads the uv source configuration;
keep the cuda13 path consistent with its existing behavior.
In `@src/physiotwin4d/mesh_web_viewer.py`:
- Around line 252-342: Update _preload_point_frames and its fast-path consumer
to cache and apply per-frame openusd_rgba data, including time-sampled
displayColor, displayOpacity, and material values, alongside point coordinates.
Ensure each frame updates both geometry and visual attributes, or bypass
preloading when those attributes vary incompatibly. Add a two-frame regression
test verifying color and opacity changes.
- Around line 239-250: Update _collect_time_codes to include time samples from
UsdGeom.Xformable transforms on each mesh and its ancestors beneath root_prim,
while retaining the default (0.0,) result when no samples exist. Add a
regression test that exercises sampled transforms at 0 and 2 and asserts
mesh_at_index() produces different evaluated positions.
In `@tests/test_tutorials.py`:
- Line 448: Extend the test around the lung-only labelmap assertion to load both
persisted labelmaps, derive the expected lung-only array from the configured
lung label IDs, and assert the lung-only content matches it rather than checking
existence alone. Preserve the existing output-path validation and use the
tutorial’s configured label identifiers and established array-comparison
utilities.
In `@tutorials/LUNG_TUTORIAL_COMMANDS.md`:
- Line 12: Replace inline HF_TOKEN assignments with a non-echoing prompt or
secret-managed environment variable in tutorials/LUNG_TUTORIAL_COMMANDS.md lines
12-12 and 53-53, and tutorials/LUNG_TUTORIAL_WALKTHROUGH.md lines 16-16 and
53-53; apply the same secure pattern at every listed site and preserve the
existing bundle-download commands.
In `@tutorials/LUNG_TUTORIAL_WALKTHROUGH.md`:
- Around line 95-100: Recompute the documented storage requirement in the
tutorial to include the persisted Hugging Face cache alongside installed
profiles, then raise the minimum above 20.57 GiB with allowance for checkout,
Docker layers, and regenerated outputs. Update the corresponding threshold in
check-host.sh to use the same minimum.
In `@tutorials/tutorial_10_lung_infer_physicsnemo_mgn.py`:
- Around line 144-153: Update prepare_checkpoint_compatible_lung_case usage to
include mask_dilation_mm, distancemap_squared_max, and ICON weight identity in
checkpoint-cache provenance so changed fit inputs invalidate stale results:
tutorials/tutorial_10_lung_infer_physicsnemo_mgn.py lines 144-153 and
tutorials/tutorial_11_lung_evaluate_physicsnemo.py lines 160-168. At
tutorials/tutorial_11_lung_evaluate_physicsnemo.py line 190, ensure ground-truth
assembly consumes outputs validated against the current fit inputs; use the same
complete provenance in both preparation paths.
In `@utils/create_motion_comparison_usd.py`:
- Around line 60-67: Update the topology validation in the frame-processing flow
to store the first frame’s cell connectivity alongside its point and cell
counts, then compare each subsequent mesh’s connectivity against that reference
before appending it. Keep the existing topology-count validation and raise the
same conversion error when connectivity differs.

Awesome work!
The helper created to generate data that should be stored in files from Tutorial 08 suggest that I might have a bug in the globbing or tutorial 08 didn't complete successfully. I will investigate and report back. Let's not merge until that bug is resolved.

I am not certain why this is needed. The files "tutorials/output/tutorial_08_lung/Case*/Case*_T??_ssm_surface.vtp" are the shape model fit to the patient for that T?? phase, with point-by-point correspondence to the shape model. This appears to be repeating that work - warping the Case*Pack_ssm_surface.vtp file (the baseline heart shape) to each phase using the saved transform. Perhaps I am missing something?
...and perhaps I have a file naming bug! I'll investigate. Also, tutorial 08 could have failed, producing the need for this work-around. In theory, if the transforms exist in the tutorial 08 output directory, then the already warped shapes should be there as well.

You are right, the workaround was generated due to a missmatch in vertices in the PCA mean template. I removed the alternative PCA mean template, and changed the code back to using the previously configured results.

The lines above are the correct ones.
Maybe your tutorial_08 didn't complete correctly so those files are missing.
Also, I renamed these files at one point, and I could have messed up and release a version with incompatible naming!!! This could be 100% my fault.

Line above is correct. Shouldn't need the transforms since we have point correspondence between the pca_mean.vtp and the patient's SSM surface.

Python 3.11 tarfile.data_filter extractall filter availability official documentation
💡 Result:
In Python 3.11, the tarfile.data_filter functionality was backported as a security update beginning in version 3.11.4 [1][2][3]. This feature allows the use of a filter argument in the TarFile.extractall and TarFile.extract methods to control how archive members are processed and to mitigate directory traversal and other security risks [1][4][5]. Key details regarding this feature in Python 3.11 include: 1. Availability: While originally introduced in Python 3.12, the extraction filter mechanism was backported to Python 3.11 starting with version 3.11.4 [1][6][3]. 2. Usage: You can check if the feature is available in your current Python 3.11 installation by using hasattr(tarfile, 'data_filter') [1][5][3]. 3. Recommended Best Practice: Because the availability of this filter depends on the specific minor version/patch level (e.g., 3.11.4 or later), official documentation recommends using a defensive check [1][5]: if hasattr(tarfile, 'data_filter'): my_tarfile.extractall(filter='data') else: # Handle the lack of filtering or warn the user my_tarfile.extractall Note that the 'data' filter itself has been subject to subsequent security vulnerabilities (such as bypasses allowing path traversal), and researchers advise keeping your Python installation updated to the latest patch version to receive the most recent security fixes [7][8][9]. Official documentation continues to emphasize that even with the 'data' filter, the tarfile module is not intended for extracting untrusted archives without additional inspection [5][3].

Support all declared Python versions for archive extraction.
pyproject.toml declares Python >=3.11, but Python 3.11.0–3.11.3 do not provide tarfile.data_filter. Bundle installation can therefore raise AttributeError before extraction on supported runtimes. Require Python >=3.11.4 or use the validated fallback when the API is unavailable.

In `@utils/lung_bundle.py` at line 44, Update the archive extraction filter around
tarfile.data_filter to support declared Python 3.11 runtimes: either raise the
minimum Python requirement to 3.11.4 or, preferably, detect when data_filter is
unavailable and use the validated fallback while preserving the existing
filtering behavior.
Use the existing 282,782-vertex lung model data directly across Tutorials 8-11 and pin the matching workshop bundle, avoiding a second checkpoint-domain fit.
Route bundle downloads through the selected Docker access mode and deploy the verified v0.3-cu126 image.
Remove redundant workshop helpers and documentation while keeping the Hugging Face bundle installer and Docker runtime reproducible.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Fall back to the full stem when the shared prefix consumes it.
If two inputs have the same stem, os.commonprefix returns the whole stem. The trim loop then keeps the part up to the last separator, and short_name becomes an empty string. Example: monai-physio-view-meshes runA/pred_lung.vtp runB/pred_lung.vtp produces two empty labels, so the visibility checkboxes at line 476 have no text.
Use the stem when the shortened name is empty.

short_name = stem[len(prefix) :] if prefix else stem

Guard against concurrent playback tasks.
_toggle_playback creates a new _play() task on every False→True transition. It does not cancel a previously created task. A prior task only exits when it observes playing as False at line 608 or line 611. If the user pauses and resumes inside one frame interval, for example 83 ms at 12 fps, the prior task never observes the paused state and keeps running. Two loops then write frame_index from different started and first_index baselines, so playback jumps between two schedules.
Track a playback generation and exit stale tasks.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Support the full declared Python 3.11 range during bundle extraction. The package supports Python 3.11, but Python 3.11.0–3.11.3 lack both TarFile.extractall(filter=...) and tarfile.data_filter. The reachable bundle installer therefore fails before extracting its first archive on those versions. Add a safe pre-3.11.4 fallback, or raise the minimum to Python 3.11.4 and update the version declarations consistently.
