ctp-skill skillA
ctp-skill is agent-read markdown (skill) from cuhk-aim-group/neurodiscovery: Process 4D CT perfusion (CTP) time series and supplied Tmax, CBF, CBV and MTT maps, including rigid motion correction, AIF/VOF-based deconvolution, spatial/unit validation and ROI/QC outputs. Use for CT perfusion, not ASL or DSC perfusion MRI..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# CT Perfusion Skill Research workflows for NeuroDiscovery. Read [the input and method contract](references/input-contract.md) before processing data. These reference implementations are not clinically validated diagnostic software; do not label an ischemic core, penumbra, treatment eligibility or patient outcome from their maps. ## Choose the input route - **4D CT:** accept a NIfTI HU series and acquisition timing, reviewed precontrast frames, brain mask and arterial input function (AIF) mask. For DICOM, first use a validated converter with rescale slope/intercept and per-frame acquisition timing preserved; never guess slice ordering or time units. Shuttle/per-slice asynchronous data need explicit upstream temporal reconstruction. - **Unaligned frames:** use `scripts/motion_correct.py`, inspect motion and all-frame coverage, then save a reviewed metadata file. Do not declare registration good just because the optimizer stopped. Register/select all masks in the fixed frame. - **Already derived maps:** use `scripts/ctp.py summarize`. Require units and a common affine/grid; never infer vendor scaling or replace missing-value codes with meaningful zero perfusion. …

How to install
mdr add cuhk-aim-group/neurodiscovery/ctp-skill@git:20260914.cfc1dd5mdr add cuhk-aim-group/neurodiscovery/ctp-skill@sha256:467773abd4331798Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
