Nickolas,

The warning message indicates that 4 columns in the design matrix are all 0s. Add option -x1D in your 3dDeconvolve script, and spill out the design matrix. Then use tools such as 1dplot, ExamineXmat and xmat_tool.py to figure out what those zero columns correspond to in your stimulus timing file Listen.1D.
