I used 3dTstat to generate a BRIK containing the mean of each voxel for a time series. The datum type of this output according to 3dinfo is float.

However the datum type of the timeseries file I want to scale is short, with no scalar attached (scanner values).

Will the following 3dcalc command work? Or do I need to convert one these files so that they are of the same type?

3dcalc -a TIMESERIES_file+orig -b MEAN_file+orig -expr '((a-b)/b)' -prefix BLAH+orig
