Hi, Marsbar users,
After I extracted percent signal change and contrast values for each condition in my 2*2 study, I run ANOVA to both measures. However, the two measures gave different results: percent signal change showed a significant effect of one condition, whereas contrast values did not show any significant results. Can anyone tell me the reasonn for this cosistency and which measure should I use for further analysis? Thanks!
