#11 Index exceeds matrix dimensions.

HI,
I'm no longer having difficulty with empty voxels
(thanks for the fix!) but am now hung up on the
following error which occurs whenever I try to compute
signal change for a block design

SPM99: spm_tbx_roi (v2.31)

SPM99: spm_roi_getSPM (v2.35)

If it helps to know: I'm trying to extract the %
signal change in a single subjec. Any ideas?
Thanks,
