Thanks for the effort of bringing pynifti (and pymvpa) avaliable. For me (on Ubuntu 9,04, or Mac Leopard)
$ sage -i pynifti-p0 unfortunately did not work directly. However, downloading the sources 'pynifti_0.20090303.1.tar.gz' and 'pymvpa_0.4.2.tar.gz', then $ sage -sh and $ make all and $ python setup.py install in the unpacked directories of pynifti_... and pymvpa_... , respectively, works OK, i.e. sage: import nifti sage: import mvpa On the Mac (Leopard) I have problems with the nifticlib 1.1 library (i.e. $SAGE_HOME/local/lib/python2.6/site-packages/ nifti/_clib.so, 2): Symbol not found: _Xznzclose ) that must be installed before the punifti or pymvpa packages. - Arvid Lundervold On Aug 6, 4:28 pm, Marshall Hampton <hampto...@gmail.com> wrote: > I have a proposed experimental pynifti package, tracked as ticket > #6678: > > http://trac.sagemath.org/sage_trac/ticket/6678 > > -Marshall > > On Aug 5, 10:23 pm, Marshall Hampton <hampto...@gmail.com> wrote: > > > Maybe this was some sort of path issue I don't understand, but when I > > tried things again it seemed to work, i.e. if I go into my SAGE_ROOT > > folder and use either sage or the sage python, the "import nifti" > > works.
