Dear HCP list, We’re interested in clustering of subcortical structures in the HCP resting-state fMRI data and have two questions regarding the pre-processing:
1. We’re looking for a way to flip the data of the two hemispheres, including subcortical structures, It seems that an option exist to do his for the surface (-surface-flip-lr). Which procedure would you recommend for flipping the hemispheres of the whole brain, including the volume data? 2. Moreover, we’re thinking of applying wb_command -cifti-smoothing to the individual dtseries files with a fwhm of 3mm for subcortical structures to make the clustering more robust. Our approach would be to smooth across subcortical boundaries. What would be your advice? Has anyone got advice with regards to the kernel size? And finally, why do we need to indicate a left and right surface file in the command? How are these files used the smoothing process (and do they have to correspond to the surface from each individual)? Thank's a lot!
