[VoxBo] contrast limit in rfx

Hi there,

I'm trying to run an rfx script that uses a relatively long and complex
contrast.  The contrast is complex because we were very specific about
naming our trial types to include information about the previous trial.
Individual GLMs look ok, but any rfx scripts crash.  Is there a limit on the
number of items that can be included in an rfx contrast?  The # of
conditions in my contrast matches the # in the contrasts.txt.  I'm just
trying to figure out what else might be causing this...

One of my scripts is located here:
/jet/ling/ANT_MED01/scripts/ling/06_rfx/prevtrial_t1t2/ t1_inc-con.vbp

Thanks!
Ling
