Three normalized brains for displaying data are located here:
\\Gall\Programs\User_Scripts\karlBrains
They are standard mulitples of 180x216x156 for displaying normalized data at various resolutions (big, half, small). Also there is a skull-stripped full size anatomical in the same folder. These images are from the spm T1 template and have been upsampled then and/or scaled down to fit 45x54x39 normalized functionals by Chris Petty.

they were in-fact created from the single-subject-T1 brain. The normalization parameters were changed to the ones we always use (.875x.875x.875), then the brain was normalized to itself, only changing the voxel size ... then padded with zeros to become a direct multiple of our normalized functionals (180x216x156 ... .875x.875x.875). The skull stripped brain was created in MRIcro. |

Out of curiosity I checked to see if any of the canonical or template brains had changed between SPM99 and SPM2. Here is what I found:
templates\EPI - Same
templates\filT1 - Only in SPM99
templates\PD - Same
templates\PET - Same
templates\SPECT - Different
templates\T1 - Same
templates\T2 - Same
templates\Transm - Same
canonical\avg152PD - Same
canonical\avg152T1 - Same
canonical\avg152T2 - Same
canonical\avg305T1 - Same
canonical\single_subj_T1 - Same
The SPM99 brains use the Analyze 7.5 with SPM modifications format and the SPM2 brains use the MINC format. I only checked that the image data were the same. Other metadata may be different. |

This brain has too much detail to be created from the SPM99 T1 template brain.
(\\Gall\Programs\MATLAB\spm99\templates\T1.img)
Were these images created from the SPM99 single subject T1 canonical brain?

the bkarlBig.img is a skull stripped anatomical |
