There are some advantages about using custom template in VBM based analysis
In many papers, authors provided following steps to create custom template
1. individual T1 image normalize to T1 template (Which is provided by SPM2)
2. Average normalized T1 images and smooth with 8mm gaussian kernel
My question is "the custom template" should be in radiology orientation or
in neurology orientation ? If the T1 template (Which is provided by SPM2)
is in the neurology direction , maybe i need to flip my custom template ?
PS: The defaults.analyze.flip value is set to 1 in spm_defaults.m
