Also to Steve: if these are used after ICAFIX, don’t they need to have the 24 motion parameters and noise ICA component timeseries confounds regressed out as well, before being used on the cleaned data?
Peace,

Note that a major reason we didn’t use these physiological confound regressors was they don’t exist for every subject, so be sure to select a subset of subjects that have them. We’d also be interested to know if you found they were helpful.

Hi Derek
Please notice that model=3 is not officially released yet in FSL. Also, there
should be a future HCP release in the near future including bedpostx results,
with the optimal parameters.

urgh - yes you're right.

Not only that, but just because a given physiological trace exists, doesn't necessarily mean that it is a *good* trace. There is going to be considerable variability in the quality of the physiological measurements, which presents a challenge in using
them in a large scale study. I'm sure
Hello,
I am trying to analyze the preprocessed diffusion data, however, I am having
some difficulties. Is there some documentation that I could look at that
outlines how to use bedpostx, FLIRT/FNIRT, DTIFIT and probtrackx with this data?
From what I've found in the archives, I need to do the
Hi - I think you would probably be best off taking the FIX-cleaned version of
the data, and then apply additional confound regressors if they will help.
Don't forget to apply the same highpass filter (to those regressors) that was
applied already in the data preproc, before you use them.
Dear all,
Is it correct that until now the physiological monitoring data is not
made use of in the preprocessing of the rfMRI data? I would like to
correct for cardiac and respiratory signals and wondered how to best do
that. I can see that FIX-denoising probably takes care of this type of
Hi again Giles,
by mistake I sent you an intermediate version of the m-files.
Please ignore the scripts from the previous e-mail and please find the
proper version attached here.
