nifti-mrs-plus

Efficient, backend-agnostic batching of NIfTI-MRS spectra

nifti-mrs-plus wraps a list of NIfTI-MRS objects into a single batch-aware tensor, keeping the header, dimension tags, and provenance intact. It materializes in whatever backend your pipeline needs (NumPy, PyTorch, JAX, TensorFlow, or Keras) with no code changes.

Install

pip install nifti-mrs-plus                   # core (numpy + nifti-mrs)
pip install "nifti-mrs-plus[torch]"          # + PyTorch
pip install "nifti-mrs-plus[viz]"            # + plotting (matplotlib + fsl-mrs)
pip install "nifti-mrs-plus[all]"            # everything

Extras: torch · jax · tensorflow · keras · viz · hdf5 · all · dev

Quick start

from nifti_mrs_plus import NIfTI_MRS_Plus, Backend

batch = NIfTI_MRS_Plus(nifti_list)

batch.shape                          # (8, 1, 1, 1, 2048)
batch.numpy()                        # np.ndarray, cached
batch.get_data(Backend.PYTORCH)      # torch.Tensor  (if torch installed)
batch[0]                             # NIFTI_MRS  (single subject)
batch[0:4]                           # NIfTI_MRS_Plus  (sub-batch)
