The entire 4D volume is rescaled by the 4D mean. On 12/11/17 2:13 PM, Taylor, Johnmark wrote: Hello, When using preproc-sess and selxavg3-sess, how is global mean scaling handled?

[Freesurfer] Global Signal Scaling in FSFAST Pipeline
Hello, When using preproc-sess and selxavg3-sess, how is global mean scaling handled? Is the session-wide (4D) mean subtracted, is each volume's mean subtracted, or neither?
