Hi,
I am examining the difference in significance between different scan parameters in a retinotopy experiment and analysis. I have loaded the sig.nii.gz file in matlab using MRIread, and I am confused by the dimensions of the "volume". I understand that this is a surface based file, but the dimensions of my sig file from the eccen subfolder are: 1 148498 1 2
Obviously the ones are not a problem and the 148498 refers to the number of vertices in that hemisphere. What does the 2 mean? What is that second component? (note this is using 5.1.0).
Thanks, Dan
