[Insight-users] DescentDirection parameter for deformable registration

[George Iordanescu]

Hi everybody,

I have a question about deformable registration parameters:

I am not sure how to set the DescentDirection if I use the ncc or MI
Similarity metric.

My current file looks like this:

0 0.99  % Similarity metric (0=mean sq, 1 = ncc, 2=pattern int, 3=MI,
5=demons)
1.0	% Alpha
0	% DescentDirection (1 = max, 0 = min)


Can I use this:
1 0.99  % Similarity metric (0=mean sq, 1 = ncc, 2=pattern int, 3=MI,
5=demons)
1.0	% Alpha
1	% DescentDirection (1 = max, 0 = min)

Thank you for your help,

George
