Hi,

I have generated white matter regressor files for resting state analysis using fcseed-config and fcseed-sess. The resulting files include: wm.dat, wm.dat.pca-stats.dat and wm.dat.log.

How do I interpret the wm.dat.pca-stats.dat file? There are 388 numbered rows (I'm guessing one per acquisition since # of acquisitions is 388?) and five columns. What do the columns represent?
