I have a MATLAB program that reads a 256x256x190 NIFTI image, processes it to get 4D image data, and writes the resulting 4D data out as a binary file of floating point vales. I'm then trying to use an AFNI program to convert the binary file to a NIFTI image with the same geometry and orientation as the original 3D NIFTI image, with the exception of being 4D rather then 3D. This seems like it should be a simple thing to do, and to3d almost works, but it's not setting the orientation properly. I've looked through the AFNI command line documentation, and I haven't found any solution, so any help would be appreciated. The 'to3d' command I'm trying to use and the input and resulting image formats are shown below. Thanks in advance!

Cheers,
Steve
