Hi, I've run FLAME 1+2 using flameo on the terminal with and without outlier modeling for one group of subjects. The commands I used are:
1) No outlier modeling
flameo --cope=Beta.nii.gz --varcope=Var.nii.gz --mask=Mask.nii --dm=test.mat --tc=test.con --cs=test.grp --runmode=flame12
2) Outlier modeling
flameo --cope=Beta.nii.gz --varcope=Var.nii.gz --mask=Mask.nii --dm=testOutliers.mat --tc=testOutliers.con --cs=testOutliers.grp --runmode=flame12 --inferoutliers
The three files for option --dm, --tc, and --cs were generated with the FSL GUI. I have two questions:
(A) What are the following two output files? Are the results from Stage 1? Why lower and upper?
zflame1lowertstat1.nii.gz
zflame1uppertstat1.nii.gz
(B) The analysis with outlier modeling took more than two times longer time than the one without outlier modeling, but the results without and with outlier modeling are identical. Does it mean that no outliers were identified in the analysis? Or something is wrong with my commands?
Thanks in advance,
Gang Chen
