  • id index: identifier to find unique string for each subject
  • filetype: files in the filetype will be searched in input directories.
  • input dirs: directories can be input either using a .txt file or spm select window.
  • out dir: output directory for saving results.
  • Meaning of results:
    • max-abstranslation(mm): maximum translation. Estimated as the max absolute value of the first 3 columns from rp*.txt
    • max-absrotation(deg): maximum rotation. Estimated as the max absolute value of the last 3 columns from rp*.txt multiple by 180/pi.
    • From van Dijk et al., Neuroimage 2012
      • max-motion-Dijk(mm): maximum root-mean-square of translation.
      • mean-motion-Dijk(mm): mean root-mean-square of translation.
      • num-movements-Dijk(>0.1mm): number of micro-movement. The number of root-mean-square of translation that is greater than 0.1mm
      • mean-rotation-Dijk(deg): mean absolute Euler angle
    • From Power et al., Neuroimage 2012
      • mean-FD(mm): frame-wise displacement. Estimated using translation and rotation.
      • num-FD>0.5: number of frame-wise displacement that is greater than 0.5mm.
