Brief description of each motion correction procedure.
Procedure | Method |
---|---|
1 | Traditional motion correction: regression of BOLD data with six rigid motion parameter in pre-processing |
2 | The six rigid body frame to frame parameter were used as a covariates to generate partial correlation matrices |
3 | Same as Procedure 2 but uses FD as a covariate |
4 | Same as Procedure 1 but regressed the BOLD data with six rigid body frame to frame parameters |
5 | Group level correction: mean FD is covaried while cross-correlating connections across subject age |
6 | Movement matching: removed subjects to make sure there was no relation between mean FD and age |
7 | Frames having FD > 0.2 mm were removed (scrubbing). To account for temporal blurring one frame before and two after were also removed |
8 | This is combining Procedure 7 and Procedure 6 i.e., frame censoring and movement matching was done |
9 | Same as Procedure 8. Instead of FD > 0.2, frames were removed based on DVAR > 4, then the movement matching was done with mean DVAR and age |
10 | Utilizes a polynomial generated for each subject based on information obtained from Procedure 7 to correct for the effect of movement |
