The -log 10(p) image contains negative values, and when we convert these these values into p-values, we get p-values greater than 1. Is there possibly something wrong with the image? The sig.mgh histogram looks like a t-distribution (viewing with tksurfer...Configure Overlay Display...also after converting to ANALYZE format as viewed by fslview:Image Histogram).
Thanks, Eric

They are signed by the contrast. To convert to a p, take the abs first.
