Dear FSL experts,
I am running a dual regression on the rsn20 template.
To do that I am using the following command:
/usr/local/apps/fsl/5.0.11/bin/dual_regression rsn20.tlrc.nii.gz 1 -1 1 outout.DR.`cat fileName.`
However, I have been reading that it is important to first run melodic and then perform denoising in the data using:
fsl_regfilt -i filtered_func_data -o denoised_data -d filtered_func_data.ica/melodic_mix -f "2,5,9"
Question:
1. Is that correct?
2. What would happen if I do not run melodic followed by denoise before performing dual regression here?
Also, in my dual regression I have two groups sometimes three.
3. should I perform melodic and fsl_regfit on all groups together or each one separately?
Thank you , Jasmin
