Brief description
The b2k and b2kf images ("b" for baboon, "f" for blood flow) are intended for use as templates for automated 3D image registration algorithms for neuroimaging stidies in baboons. The b2k template is an average (after spatial normalization) of T1-weighted MRI images from 9 normal baboons, and the b2kf template is averaged from 397 [15O]water PET images in 7 normal baboons. Coordinates from the 1968 Davis and Huffman photomicrographic atlas of baboon brain can be derived from pixel coordinates in these images according to the conventions described in the attached appendix.html file (they are automatically computed by SPM based on the supplied .hdr files). Details of the images' formation and a test of the accuracy of our image registration software when registering MPRAGE and PET blood flow images to these templates appear in NeuroImage. The GIF files show a quick view of one slice of the template images. Corresponding images are also available for use with Macaca nemestrina (the pig-tailed macaque) and Macaca fascicularis (cynomolgus monkey).

*The "tight" mask approximates actual brain and was created by hand from b2k.4dfp.img using Analyze AVW. Its volume is 185 ml (185479 voxels). Note: Bonferroni correction for overall p < 0.05 with 185479 independent tests is p < 2.70 x 10-7, corresponding to a Z score of about 5.14 (two tails) or 5.01 (one tail). The loose mask (used for image registration with our local software) was created by dilating the tight mask slightly; its volume is 242 ml (241739 voxels).
