Dear experts,
I (think I) understand how to do a PPI from the menu and am now trying to
use the PPI batch editor. Using the menu, I can simply choose which
conditions to include and choose the weight so I end up with a 1 and a -1
for two different conditions. Using the batch editor, it asks for a [n x
3] matrix. Letīs say I have 3 sessions and 3 conditions and I am
interested in the PPI for condition 1 > condition 3. Am I correct that the
matrix would need to be
1 1 1
1 1 0
1 1 -1
2 1 1
2 1 0
2 1 -1
3 1 1
3 1 0
3 1 -1
Or am I completely off?
Many thanks in advance,
Mante
