Hi, All

Every time I try to enter images into a VBM2 cross sectional analysis I get this error:

>> Use the 'Estimate' button to estimate parameters
>> ??? Attempted to access CPos(-2.14748e+09); index must be a positive integer or

Does anyone know why this error is occuring? I was able to to analyses on these same images just a few day ago with no problems and I've never had this problem before. I'm using MATLAB 7.1 and SPM2. Any and all input on the nature of this error and how to fix it is appreciated!

Thank you,
