Hi all,

After preprocessing my data using fmriprep, I would like to run my voxel-wise BOLD regression in T1w volume space and then sample my results to fsnative surface space. Does anyone know which registration file fmriprep uses to sample the BOLD time series in original space to the fsnative surface space? And is there a transformation matrix in the fmriprep output which would give me those voxels used to create the BOLD time series in surface space later on so that I can limit the number of voxels in my regression beforehand?

Thank you so much for your help!
