Dear Alina,
How did you extract the data for a given voxel? What is displayed if,
when looking at results, you move the 'current voxel' (red arrow) to
your voxel of interest and do a right click while on the glass brain and
select Extract data > betas > this voxel in the contextual menu that opens?
Best regards,
Guillaume.
