Dear Doug,
I don't know if I am doing something wrong but when I run the simulation under
QDEC I am not getting the csdbase.y.ocn.dat file. The only files that I get
under after running the simulation under QDEC are:
mc-z.abs.th20.sig.cluster.summary,
mc-z.abs.th20.sig.ocn.annot,mc-z.abs.th20.sig.ocn.mgh while QDEC output file
are: Contrasts, lh_Avg-Intercept-thickness, lh_Avg-thickness-Age-Cor. In the
last two files I have sig.mgh so I am not sure on what file should I run the
simulation and why Monte Carlo does not give me as an output the file I want as
a .dat.
Because I want to do a study and eliminate age, I choose as a Continuous
Variable: Age and as a Discrete Variable: Class and I highlight them in QDEC in
the Design window. What if I my discrete variable is not highlighted? Also, Age
is coming under Nuisance Factors but do I need to highlight this?
Thank you very much for your help.
Antonella

You can run mri_glmfit-sim on the QDEC output directory. Or you can run
the simulation from within QDEC. Both will give you this output file.
