You need to use the standard spheres of the current and lower resolution grayordinate space, using the -left-spheres and -right-spheres options. The volume part of the resampling assumes the identity transform if you don't specify a volume option.
As the command help says, to use it on a dconn, you need to run it on the original dconn (using ROW for <direction> first for less memory usage when downsampling), then again on the output of that (using COLUMN), to obtain a second output that is the lower resolution on both directions.
