NV-Generate-MR-Brain-Finetune

Purpose

• Used for finetuning the NV-Generate-CTMR rflow-mr-brain v1 diffusion UNet from user-supplied T1, T2, FLAIR, SWI, or MRA NIfTI training volumes.
• Not for clinical interpretation, regulatory use, or approving synthetic data for production training.
• The wrapper stages the config glue locally and delegates execution to existing upstream scripts: scripts.diff_model_create_training_data, scripts.diff_model_train, and optionally scripts.diff_model_infer. It does not execute the notebook.
• Manifest I/O: inputs are datalist and data_base_dir; outputs are finetuned_checkpoint, optional inference_outputs, and result_json.
• The underlying training contract is the upstream config/env JSON (the same one driven from cell [10] of train_diff_unet_tutorial.ipynb). The wrapper stages those JSON files for you and exposes the most-tuned fields as CLI flags; the sections below document the fields, their defaults, and how to monitor/tune a run.
