Dear Rebecca,

I don't know what the problem with marsbar is but if you just need to
access the raw data within a cluster, you can do that directly with the
latest version of SPM12 by moving the red cursor to the cluster of
interest and choose Extract data > raw y > This Cluster from the context
menu. The data will be available from the MATLAB workspace in a variable
called 'y'.

Best regards,
