I recently tried several ways of doing this with a number of structural
scans (which were in coronal orientation).
I used a tool called XMedCon (http://xmedcon.sourceforge.net) to convert
the images from dicom 2D -> dicom 3D (but you may be able to skip this
step) and then dcm2nii to go from dicom to nifti (dcm2nii comes with
MriCRoN, see http://www.sph.sc.edu/comd/rorden/mricron/dcm2nii.html)
The nice thing about NifTI is that, if the orientation parameters are
carried forward in a proper way in all your conversions, your left-right
settings are correct. Simply put, NifTI *does* store the orientation,
Analyze *doesn't*, the latter meaning that you need to re-enter is
before you start your analysis.
Of course, if you're comfortable with Analyze and you have a standard
setup for solving L-R, there's no direct need to change to NifTI. A
non-matlab (scriptable) program to convert would probably be good? I
think medcon (the command-line version of xmedcon) would do a good job.
