Create a template NIFTI v1 header. You will have to adapt it for your use case.

Usage

ni1header.template(pair = FALSE)

Arguments

pair

logical, whether the template describes a NIFTI v1 pair file (a .hdr header file plus a separate .img data file, the variant that is also used by the ANALYZE 7.5 format and that FSL writes) instead of a single file (.nii, the header and the data in one file). The two variants differ in the magic field and in the vox_offset field, which is 352 for a single file (the data starts behind the header) and 0 for a pair (the data starts at the first byte of the .img file). Both variants are written by write.nifti1.

Value

named list, the NIFTI v1 header. All fields are present and filled with values of a proper type. Whether or not they make sense is up to you, but you will most likely have to adapt at least the following fields to your data: dim_raw, datatype, bitpix.

Note

Commonly used data type settings are: for signed integers datatype = 8L and bitpix = 32L; for floats datatype = 16L and bitpix = 32L. See the NIFTI v1 standard for more options. You may want to call ni1header.for.data instead of this function.
