Dear all,
I would like to regress out the motion parameters during the pre-processing steps for resting state fMRI. Although this question was posted several times by others before, I didn't find confirmed answer.
I try to use the command:
fsl_regfilt -i input.img -o output_regression.img -d subjid.img.par -f "1, 2, 3, 4, 5, 6"
Here input imge is the 4D image processed by Slice timing, motion correction, skull stripping, band pass and intensity normalization steps. -d is designed matrix. So here I make motion parameters as a design matrix. -f: means I would like to regress out all of these 6 parameters.
I am not sure whether above command is right or not.
Any idea will be appreciated!
Thanks in advance!
Li
