What this skill does
NV-Generate-CT (rflow-ct) Purpose Used for generating synthetic CT volumes and masks with NV-Generate-CTMR rflow-ct. Not for production training data without review. Use the wrapper exactly as documented; do not replace the upstream entrypoint with a handwritten implementation. Do not write custom inference code for normal runs. The wrapper owns config staging, output paths, label mapping evidence, and validation. Manifest I/O: inputs are configinferoverride; outputs are syntheticctvolumes and resultjson. Instructions Read skillmanifest.yaml before changing arguments, side effects, or validation gates. Run scripts/runrflowct.py through the documented command below; keep outputs under a caller-provided run directory. If a host agent exposes runscript, use runscript("scripts/runrflowct.py", args=[...]); otherwise run the Bash/Python command shown below. Emit a single bash code block, and keep the python -m pip install -r "$NVGENERATEROOT/requirements.txt" step in that same command — the runtime may be a fresh environment without nibabel/MONAI, so dropping the install fails with ModuleNotFoundError. Do not add rm, mkdir, or any cleanup of --output-dir; the wrapper creates it. Use a fresh --output-dir instead of deleting one. Check the emitted JSON and paired verifier guidance before treating the run as evidence.
