Table 1:

Common fslmaths commands to spatially smooth (-s), spatially filter (-kernel), demean (-Tmean) and temporally filter (-bptf) a 3D (t1) or 4D (rest) image from the Human Connectome Project with a laptop using an Intel i5-8259u (28w) CPU. The ‘Time‘ column reports the time for fslmaths to complete (in seconds). The ‘Speed Up‘ column reports the acceleration relative to fslmaths (e.g. 2.0 means that niimath completed in half the time it took fslmaths).
