    by a dot and a numerical micro version, and / or by an "extra" string.

    compares as prior to (pre-release for) `1.2.0`, where `somestring` can be

Read / write access to some common neuroimaging file formats

This package provides read +/- write access to some common medical and
neuroimaging file formats, including: ANALYZE_ (plain, SPM99, SPM2 and later),
GIFTI_, NIfTI1_, NIfTI2_, MINC1_, MINC2_, MGH_ and ECAT_ as well as Philips
PAR/REC.  We can read and write FreeSurfer_ geometry, annotation and
morphometry files.  There is some very limited support for DICOM_.  NiBabel is
the successor of PyNIfTI_.

.. _DICOM: http://medical.nema.org/

The various image format classes give full or selective access to header
(meta) information and access to the image data is made available via NumPy
arrays.
