Dataset Files - II
¥ AFNI dataset filenames consist of 3 parts
H The user-selected prefix (almost anything)
H The view (one of +orig, +acpc, or +tlrc)
H The suffix (one of .HEAD or .BRIK)
H Example: BillGates+tlrc.HEAD and BillGates+tlrc.BRIK
H When creating a dataset with an AFNI program, you supply the prefix; the program supplies the rest
¥ AFNI programs can read datasets stored in several formats
H ANALYZE (.hdr/.img file pairs); i.e., from SPM, FSL
H MINC (.mnc); i.e., from mnitools
H CTF (.mri, .svl) MEG analysis volumes
H NIfTI-1 (.nii) Ñ a new standard format that AFNI, SPM, FSL, and BrainVoyager have agreed upon (real soon now)
H ASCII text (.1D) Ñ numbers arranged into columns
