Hi all,

Apologies for this basic question, but im quite the newbie.

I'mcurrently using tksurfer and got this result:

surfer: filling (ctrl-c to cancel).... done, 4646 vertices filled
surfer: performing FDR on 1989 vertices
MRISfdr2vwth(): np = 1989, nv = 163842, fdr = 0.05, vwth=2.24098
MRISfdr2vwth(rate=0.050000, sign=0, 1, only_marked=1) = 2.240980
surfer: MRISfdr2vwth with rate 0.05 and sign 0 returned threshold 2.240980


I was wondering what np, nv and vwth actually stand for?

Also does anyone know how to get the T or F statistic?

Thanks,
Harry
