SLOMOCO does not support the censoring option, but provides the slice wise motion index, possibly used for your censoring. Check slomoco.TDzmetric.txt file, which is slice wise time series (tdim x zdim) of motion index. You should consider the slice acquisition timing for EPI data, e.g. 3 tp data is 1st volume, 3rd slice acquisition, not the 3rd slice.
