> How do I code that in 3dDeconvolve -gltsym ?

If you modeled the resting periods as baseline (and each session is modeled with a separate baseline), then the effect estimates for A-Day1 and A-Day2 are already the contrasts against the effects of their respective resting periods. So you can simply code the desired contrast in -gltsym of 3dDeconvolve with something like

'SYM: +A-Day1 -A-Day2'
