P-values in slice viewer and xjview

Submitted by cxl298 on

when i load a simple contrast map from a 2-sample t-test onto the slice viewer and xjview, they provide me with maps with different statistics (p-values not matching).

Am i missing something?

Hi Christian,

This is because xjviewer is using one-tailed p-value, while REST Slice Viewer is using two-tailed p-value.
If you double the p-value in REST Slice Viewer, you will have the same thing.
