I have made some custom labels based on retinotopy data and I wish to export these as SPM ROIs so that I can use some specific tools.

I grouped the labels into an annotation file and I used mri_label2vol to convert it into nifti, I then imported it into matlab and I get a volume with each pixels corresponding to a number.

How can I confirm if the coordinates that I have used to export these labels are aligned well with the data in SPM coordinate system?

Thank you,

Mohamed,
