Space Software

       Space is a free MS Windows (98, 2K, XP [Vista, W7 not tested]) application for the display, navigation, rendering, editing, and measurement of 3-D data sets. In many respects it serves the same needs as a traditional 2-D image editor for 3-D data, but is organized and optimized for the particular requirements of handling 3-D data for research purposes. The program provides fast display of arbitrarily oriented planes through 3-D data, direct spatial correlation and combining of multiple spatially coincident data sets, several image processing operations, and an array of fully interactive display and rendering options for visualization. All primary functions, display elements and user interaction elements are highly integrated.

    Space is authored by Mark Dow and Greg Scott, and is currently in active, but slow, development. Space is freeware
(in the free lunch sense), but the source code is not publicly available.

    The current beta-testing versions expired at the end of December 2010, but still operates normally. Functionally equivalent and improved free versions will be continue to be available. 

        Download most recent (version .94i.1) program: (2 MB)

    There’s no installer, just unzip the files to any directory. To run, double click the Space.exe file. A registry entry will be created, but no other files are "installed".

File formats supported by Space include: For DICOM files, use MRIConvert, or other DICOM conversion programs (see idoimaging). MRIcro can convert many machine specific 3-D formats to Analyze 7.5.

To write a 3-D Matlab array to a grayscale file readable by Space, use the MATLAB script write_Space_volume.m
    Several program details and advanced tools are still being perfected, and a few ragged edges will be trimmed in the coming months. The core operations are stable and well tested.

    Comments, requests, and bug reports are encouraged. (dow[at]

   Space was partially developed at the Lewis Center for Neuroimaging and Brain Development Lab at the University of Oregon . Greg Scott, previously working at the Brain Development Lab at the University of Oregon and now in an MD/PhD program at OSHU, wrote the lion's share of code for advanced rendering, multiple layer interface tools, AVI/ANALYZE/NIFTI file read/write, movie keyframing, 24 bit editing, transparent gzipping and much more.
