Re: [Freesurfer] slice timing correction with mulit-band

Great to know that this would not cause any problems. After I did stc first and named the file with the stc stem, I tried to use -mcin, -mcout, -smin, and -smout to specific the input and output file stems for motion correction and spatial smoothing in preproc-sess. I received error messages abo

That sounds ok, I don't think it will cause problems. You can also do whatever preprocessing you want and then specify the input data with the -funcstem option to mkanalysis-sess On 6/5/18 8:16 PM, Xu, Yaoda wrote: OK, I realized that I was running under Freesurfer 5.3 and not 6.0. Once I was

OK, I realized that I was running under Freesurfer 5.3 and not 6.0. Once I was running under the correct version, things were running as intended. I was told that in fs-fast, motion correction (mc) has to go before slice timing correction (stc). For my data, I need to run stc before mc. So I fou

I tried to use preprocess-sess with -sdf, here is the error message: ERROR: Flag -sdf unrecognized. I attach here the slice timing. I saved it in a .txt file and tried “-sdf slicetimingfile” but got the above error message. Instead of using preproc-sess directly, I tried to use stc-sess to corr

You will need to know how many slice groups were used in the acquisition, fsfast will not know that. preproc-sess should accept a slice-timing with with -sdf (though this is not listed in the help). What is the error that you are getting? There is no way to do STC before MC in fsfast. When you
