We've been having some problems with our MNI registration of the fMRI data.
After going through the PreFS, FS, PostFS, and the GenericfMRIbatch scripts, we
get a 4D dataset: subjectID/MNINonLinear/Results/taskname/taskname.nii.gz
I'm assuming those 4D images should be registered to the MNI
I don¹t recommend using data with large amounts of spatial smoothing
(downsampling is actually a more forthright acknowledgement of what you
are doing to the data and saves space and computational time). Also, it¹s
worth thinking if your use case would be better served by using a brain
Dear Matt and HCP experts,
Thanks again for this.
I have some further questions:
(1) Even if my data is 1x1x1mm^3 should it be registered to the
workbench default T1 MNI of 0.7mm or to 1x1x1mm^3?
(2) Within HCP: Is it valid to also look at white matter myelin not just
cortical myelin?
(3)
An additional note on downsampling: when using the ADAP_BARY_AREA surface
resampling, you do not need to smooth before downsampling (it will not lose
data that falls between the sampling points). However, with downsampling
volume data, the available methods do require some presmoothing to avoid
