The program yields a beta-file as output.
To obtain a statistical parametric map, the program 'vgetcontrast' must be applied to this beta-file.
Example:
Let the text file 'design.txt' describe a 2-sample t-test:
% % design file 'design.txt', two-sample t-test % 1 0 1 1 0 1 1 0 1 1 0 1 . . . 0 1 1 0 1 1 0 1 1 0 1 1 . . .The following sequence of program calls first computes a beta-map, and then it computes a zmap that contrasts the two groups contained in the files conimage1_*.v and conimage2_*.v.
v2ndlevel -in conimage1_*.v
conimage2_*.v -out beta.v -design design.txt
vgetcontrast
-in beta.v -out zmap.v -con '1 -1' -type zmap
