Hi everyone,

I was wondering if someone could answer the following questions about reporting results for 3dlmer?

So, I have the following 3dlmer script:

3dLMEr -prefix /analysis/results \
-jobs 24 \
-resid /analysis/residuals \
-mask /analysis/grey_matter_mask.nii.gz \
-model "Time*Group+Age+Sex+(1|Subj)" \
-qVars "Time,Age,heartrate,RT" \
-gltCode Int-Ctlr_over_Time 'Group : 1*Intervention -1*Control Time :' \
-gltCode Int_over_Time 'Group : 1*Intervention Time :' \
-gltCode Ctlr_over_Time 'Group : 1*Control Time :' \
-gltCode Int-Ctlr_Base 'Group : 1*Intervention -1*Control Time : 0' \
-gltCode Age 'Age :' \
-gltCode Female_vs_male 'Sex : 1*female -1*male' \
-dataTable @/analysis/datatable.txt

Based on the residuals, I do cluster correction with 3dClustSim, that reports a minimum cluster size for significancy.

What would be the correct words for reporting the results of the Chi-Square tests and contrasts of 3dlmer?
I am interested in the group*time interaction, so I mainly looked at the result of [-gltCode Int-Ctlr_over_Time 'Group : 1*Intervention -1*Control Time :']
- when I get a significant result there, can I call it a significant 'interaction effect'? What is the difference to the result of Time:Group Chi-sq, which is slightly different to the other one (in regards to the cluster size)?
