Dear spmers:
I have asked the same question several days ago,I wish i can get clear answer about if i can process these image with SPM.
several days ago, I used MRIcro to open a set of Rcbf images from GE company¡¯s STARcam format(one group are patient,another is normal,one scan for each person). All the transverse image is normal, but all the coronal images like a broad ¡°Z¡± shape. The sagital images are all another strange separated shape. The size of the Rcbf image is about 2.0 Mb.
I have attached the two of the raw images into the list, any suggestion about the my questions is greatly appreciated.
thanks in advance

The header information in MRIcro is
Dimension size(mm) origin
X 128 3.24 0
Y 128 3.24 0
Z 64 1.00 0
Offset 4978 Scale 1.000
I continue to use SPM99 to prossess the images . in spatial step of normalization, i couldn¡¯t get the correct results(only process one person once a time) , Matlab stop iteself . I have submitted the error message below:
One kind of error message were:
