Added accessor/replacement functions for cal. nifti were designed to use as much information as possible from the metadata-rich DICOM format and apply that information in the construction of the NIfTI data volume. Please just raise your hand. To write image data or metadata to a file in DICOM format, use the dicomwrite function. Interpretation of the files will also be possible, since the meaning of the fields is determined, when the intent of the file is known. Derived images were excluded automatically "I was thinking: the number of mm^3 is still hard to grasp. Hathout L, Patel V, Wen P. For reading it was trivial, because zlib can transparently read uncompressed files. Tour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have The most common case for images with a dictionary is DICOM, but also the fields from TIFF, NIFTI, MetaIO and other file formats maybe loaded into the meta-data dictionary.
