Dear FS experts

I have run a group analysis on thickness and area maps and everything worked fine. When running the same analysis on cortical volume maps, the following error occurred (figures are attached):

*** CEPHES ERROR: fdtrc domain error ***

*** CEPHES ERROR: fdtrc domain error ***

*** CEPHES ERROR: fdtrc domain error ***

*** CEPHES ERROR: fdtrc domain error *** Fit completed in 0.453067 minutes Computing spatial AR1 on surface INFO: fwhmFromAR1: Fixing group surface area Residual: ar1mn=0.998253, ar1std=0.002494, gstd=10.000979, fwhm=23.550507 Writing results sad_Design maxvox sig=-1e+10 F=-18.96 at index 0 0 0 seed=1254498771 Computing kurtosis of residuals mri_glmfit done Neuromorphometer:/usr/local/freesurfer/subjects/average/stats/glm>

Any idea what is wrong?

I used FS 4.3.0 centos4 distribution on Ubuntu Linux and applied dods. When using doss and the DeMeanFlag = 1, the error did not occurred.

Thanks in advance Regard Jürgen
