Image Data Formats and Conversions
3dAFNItoNifTI converts AFNI .head/.brik file pairs to NifTI .nii files.
MRIConvert, from the University of Oregon, is a GUI utility that converts DICOM to NifTI, Anayize, SPM99, BrainVoyager and MetaImage formats. MRIConvert includes a basic DICOM viewer. McVerter, a command line DICOM to NifTI converter, is included with MRIConvert. Dcmdb uses mcverter.
The mricron package contains two conversion programs, dcm2nii and dcm2niigui. Some versions of dcm2nii do not work with our data. If you have trouble make sure you are using the latest version or try MRIConvert. (August 2016 I really should check if the dcm2nii bug is fixed yet)
FSL reads images in nii, nii.gz, NifTI .hdr/.imp pairs, and Analyze .hdr/.img pairs. FSLTUILS includes programs to convert, slice, merge, interleave, fix, adjust and corrupt your data. The util program fslchfiletype converts between Analyze and various types of NifTI.
