apply_xfm_fsl

petpal.preproc.register.apply_xfm_fsl(input_image_path: str, ref_image_path: str, out_image_path: str, warp_path: str = None, premat_path: str = '', postmat_path: str = '', **kwargs)

Applies existing transforms in FSL format to an input image, onto a reference image. This is useful for applying the same transform on different images to atlas space, for example.

Important

Requires installation of FSL, and environment variables FSLDIR and FSLOUTPUTTYPE set appropriately in the shell.

Parameters:

• input_image_path (str) – Path to image on which transform is applied.

• ref_image_path (str) – Path to image to which transform is applied.

• out_image_path (str) – Path to which the transformed image is saved.

• warp_path (str) – Path to FSL warp file.

• premat_path (str) – Path to FSL premat matrix file.

• postmat_path (str) – Path to FSL postmat matrix file.

• kwargs (keyword arguments) – Additional arguments passed to fsl.wrappers.applywarp().
