One approach is to use -gltsym in 3dDeconvolve with something like
-gltsym 'SYM: cond1 - cond2 \ cond1 - cond3 \ ... \ cond1 - cond12'
or
-gltsym 'SYM: cond1 - cond2 \ cond2 - cond3 \ ... \ cond11 - cond12'
or, more awkwardly,
-gltsym 'SYM: cond1 - 0.08333 * cond1 - 0.08333 * cond2 - ... - 0.08333 * cond12 \ cond2 - 0.08333 * cond1 - 0.08333 * cond2 - ... - 0.08333 * cond12 \ ... \ cond12 - 0.08333 * cond1 - 0.08333 * cond2 - ... - 0.08333 * cond12'
