Hello, when I try to use spm_coreg, via mrAlignMI, to co-register functional and anatomical data, and this is the output I get
iteration 1...

I managed to track it as far as finding that the first loop in spm_powell never gets to its stopping condition, but can't understand why.If it helps the registration is from 0.8654*0.8654*3 mm to 1*1*1 mm voxells.
