Hi all,
I generated concatenated data after the first PCA step by projecting eigen
vectors (dewhiteMatrix) on to the individual data-sets and stacking the
reduced data-sets. However, the concatenated data doesn't match in the file
concat_data.nii.gz (generated using --debug option in melodic). Is there any
additional pre-processing step before stacking data-sets?
I noticed that in paper
(http://www.fmrib.ox.ac.uk/analysis/techrep/tr05cb1/tr05cb1.pdf) first PCA
step eigen vectors are generated by stacking data-sets spatially. Was this
not the obvious choice because of memory limitations?
Thanks,
Srinivas
