I have tried to run a 3dLME model but got the attached error. I am trying to examine activation during levels of the task in relation to mean reaction time. The variable names in the code match the columns of the data frame, and there are no missing data in the data frame. I am not sure what could be the issue? Any insight/suggestions would be greatly appreciated.

3dLME -prefix ${output_directory}/RT_fourlevels+tlrc \
-jobs 8 \
-model 'StimType*meanRTacrossrun' \
-qVars "StimType,meanRTacrossrun" \
-ranEff '~1+RT' \
