Dear AFNI gang,
We are dealing with mean activation maps that include a great deal of deactivation, or, negative beta values and want to run contrasts now. In order for the negative values to not confound the contrasts we woud like to know if there is a way, within AFNI, to either A) set the beta values to absolute values or B) add a constant positive value?

Thanks in advance.
