Preclinical MTI-PASL Pipeline
=============================

**Runner:** ``pyasl.pipelines.preclinical_mti_pipeline.run_preclinical_mti_pipeline``

**Purpose.** Unified entry for MTI-PASL workflows (load NIfTI/Analyze, fit T1,
compute absolute CBF, save outputs).

Inputs
------

- ``data_dir``: base directory used to resolve relative paths in step params.
- ``config_path``: YAML config.

YAML Example
------------

.. code-block:: yaml

    type: mti
    steps:
      - module: NIfTILoader
        params:
          path: "data/preclinical_MTI_PASL/FAIREPI.img"   # resolved against data_dir
          target: AbsData
          savedir: "results_mti"
      - module: AbsCBF_T1Fit
        params:
          TI_list: [200, 400, 600, 800, 1000]
          sel_index: [1,3,5,7,9]
          glo_index: [0,2,4,6,8]
          save_curves_every: 300
