Hello,
I 've read this paper: Beherens et al, Neuroimage 2007,34:144-55
"we examin each fibre population to confirm that the volume fraction has not
been forced to zero by automatic relevance determination (we threshold at
0.05)."
Program(xfibres.cc) is written as
"nfibs=0;
if((m_sum_f[f]/m_nsamples>0.05)) nfibs++;
...
m_beenhere = nfibs "
But, mean_f2samples contains <0.05.
What is the meaning of "we threshold at 0.05" ?
And m_beenhere is used by "bool neighbour_initialise".
I donot understand "bool neighbour_initialise" well.
I assume (possibly incorrectly) that it decides whether to
execute "initialise_tensor".
Many thanks for your help.
