Dear FSL experts,
I would like to calculate motion estimates (DVARS, FD, RMS) for my already preprocessed subjects. I would like to compare the motion parameters before doing FIX (including the motion correction within FIX; -m) and afterwards.
1. To calculate the motion parameters BEFORE FIX I used the raw EPI data as input:
Fsl_motion_outliers –i raw_data_EPI.nii.gz –o FD –fd –s fd.txt
I averaged the motion parameters by calculating the mean of all parameters in the textfile
2. To calculate the motion parameters AFTER FIX I used the filtered_func_data_clean:
Fsl_motion_outliers –i filtered_func_data_clean.nii.gz–o FD –fd –s fd.txt
I averaged the motion parameters by calculating the mean of all parameters in the textfile
Is that the right way to calculate and compare motion parameters BEFORE and AFTER FIX?
