MRC Handles

class fouriercrop.load_mrc(load_path: str | Path, as_tensor: bool = False, get_voxel_size: bool = False)

Loads data from an MRC file and optionally retrieves voxel size.

Parameters:

• load_path (Union[str, Path]) – Path to the MRC file.

• as_tensor (bool, optional) – If True, returns tensor (default=False).

• get_voxel_size (bool, optional) – If True, returns voxel size (default=False).

Returns:

The MRC data and voxel size.

Return type:

Tuple[Union[np.ndarray, torch.Tensor], np.ndarray]

Raises:

FileNotFoundError – If the input file does not exist.

class fouriercrop.save_mrc(save_path: str | Path, save_data: ndarray | Tensor, voxel_size: float = 1.0)

Saves data to an MRC file.

Parameters:

• save_path (Union[str, Path]) – Path to save the MRC file.

• save_data (Union[np.ndarray, torch.Tensor]) – Data to save.

• voxel_size (float, optional) – Voxel size of the data (default=1.0).
