It is in -log10(p). There will be the vertex number for the max in that file. You can load up the F.mgh file to get the F-value for that vertex. Assuming your contrast matrix only has one row, then t = sqrt(F). You can compute the z-value in matlab. first convert the -log10(p) to a p-value with p=10^(-abs(sig)) then use fast_p2z (in matlab) to convert the p to a z.
