A few questions about the workflows of fMRIPrep

[Steven]

Hi @younghoo,

@younghoo

Do these dummy scans affect subsequent processing steps?

Please read previous response here: Fmriprep --dummy-scans purpose? - #2 by effigies

@younghoo

Is STC performed on the raw (input) BOLD data or on the motion-corrected BOLD data?

STC is applied to the motion-corrected BOLD.

@younghoo

is it recommended to perform denoising procedures in standard space while the confounding signals are derived in native space?

You should denoise in whatever space you want to analyze data in.

@younghoo

How does fMRIPrep select the registration target? For example, in the command above, I requested the BOLD data to be resampled to the res-2 resolution of the MNI152NLin6Asym template. Which resolution of that template is used to derive the registration warp field?

I believe the T1w registration step uses the best resolution available for the specified template family. The resampling happens separately.

Best,
Steven
