Dear experts I has obtained two ROIs (corrected FDR) difference between AA and GG regressing out the effect of age and gender using the QDEC with attachment, following extract the average surface area of two ROIs to analysis using SPSS, in which I used the Univariate Analysis of Variance to find the difference between AA and GG, gender and age as covariates, but find that there no significant in these ROIs, I want to know why there were significant difference in QDEC, but no significant difference in SPSS? I hope that have experts to help me, thanks!

Hi Bo, you need to make sure that you have exactly the same design matrix in SPSS. The design matrix for qdec is Xg.dat in the output directory. How did you extract the data out of the ROIs?

I drawing two ROIs in two clusters, and mapping two labels to all subjects, following extract the average surface area of two ROIs from every subject. Anyway, whether have command to direct obtain the label of two clusters, not to drawing the ROIs from these clusters, then there have exactly data to be obtained. Thanks! Ho Xiang

That technique can yield inconsistent results when the ROI is small (as in your case). You are better off extracting the data directly from the input to mri_glmfit. This is created by QDEC and is called y.mgh. This will be a file with number of frames equal to the number of subjects.

Dear experts
I has obtained two ROIs (corrected FDR) difference between AA and GG regressing out the effect of age and gender using the QDEC, following extract the average surface area of two ROIs to analysis using SPSS, in which I used the univariate analysis of variance to find the difference between AA and GG, gender and age as covariates, but find that there no significant difference in this ROIs which from region to region, and the other is significant difference between AA and GG, I do not know whether these different result were influenced from region to region? I hope that have experts to help me, thanks!
