Create ideal response files, in case the user wishes to plot them in the graph window along with the time-series data.

• Create ideal response files, in case the user wishes to plot them in the graph window along with the time-series data.

• • These are the main regressors of interest.
  • The BLOCK(30,1) basis function produces only one regressor. For basis functions that create multiple regressors, this 1dcat operation is skipped.
  • • 1dcat X.xmat.1D'[27]' > ideal_tneg.1D

• As the user requested, create sum_ideal.1D.

• • Supposing a voxel responds equally to all regressors of interest, this shows the expected shape of that response.
  • This is another good way to check for incorrect regressors.
  • • 3dTstat -sum -prefix sum_ideal.1D X.xmat.1D'[27..35]'
