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 wit

Hi there, I have a couple of questions about the mri_glmfit-sim output files. First, in the mc-z.whole.absolute.sig.cluster.summary file, is the "Max" a z-score or t-score? I have seen it referred to as -log10pvalue, but is there a place where I can find the z- or t-score? Second, are the number
