Hi Lorena,
The designs should be identical between the two methods _however_ there will probably be minor numerical differences between the two runs due to subtle changes in things like how the data mask is generated when pre-stats is disabled. Note that both motion-parameters and "other" confound EV files should be treated the same way with respect to filtering etc.
Kind Regards
Matthew

Can I just run the Stats + Post-stats using the filtered_func_data.nii image as input and add the motion parameters by clicking the "add additional confound EVs" button in the Feat GUI loading in the "prefiltered_func_data_mcf.par" file from the original feat directory? Do I get the same results as if I run prestats, stats and post_stats in the same FEAT run using "add motion parameters to the model" button.
