I've modified an analysis to include a vector of noise time courses estimated using ICA. Since IC effects should be consistent across runs, I'm using taskregs instead of nuisregs. I can define the analysis and set up contrasts fine; however, when I run the analysis (selxavg3-sess), I get the following error:

[...]

Error using zeros
Size inputs must be integers.

Error in fast_selxavg3 (line 1248)
hhattmp = [zeros(Navgs_per_cond,nvox); hhattmp]; % Add zero for cond 0

>> ------------------------------------------

============================

Looking at h.dat, I notice "Nh" is set 3.625000e+00 rather than "1" as usual.

Any tips on how to debug further?
