I have a question about the preprocessing for the task-fMRI
grayordinates datasets, specifically the images from the Level 2
fixed-effects analysis. For clarity, the images I'm asking about are
From Barch et al. (2013) and the HCP_S500 Reference Manual, these
participant-level analyses were performed with a grayordinates-adapted
version of the FSL Level 1 and Level 2 analysis routines, using as input
the output of the fMRISurface pipeline.
Which brings me to the question: Is it correct that the pipelines
producing these images perform (amongst other preprocessing steps)
motion correction and spatial normalization (MNI atlas registration) on
the fMRI images in volume space, before the surface mapping? Figures 19
and 20 in Glasser et al. (2013) suggest that this is the case, but it is
a bit unclear.
