You can't  on either occasion just using preproc-sess. You can create an analysis with those components, then run selxavg3-sess with the -svres option. This will create a folder called eres with volumes that have had all the nuisance variables and low freqeuncies regressed out

Thanks.

1- By using only preproc-sess, how can I perform "band pass filtering"?

2- And how can I take in account the nuisance variables: the CSF from which the top 5 principle components, the white matter from which the top 5 principle components, motion correction parameters (-mcextreg), 5th order polynomial. How can I eliminate the first 4 time points?

just use preproc-sess

Hi list,

in FS-FAST, on rs-fMRI data, is possible to run selxavg3-sess without -a option?

I would use whole the FS-FAST to preprocess my data. I would include the mkanalysis-sess step but I would not perform a seed-based analysis. 

Thanks

Stefano
