Dear Freesurfer team,

In the mri_glmfit-sim summary output file, I get a number of output variables, and I'm not sure what some of them are. Could you explain the ones in bold to me?

# ClusterNo  Max   VtxMax   Size(mm^2)  MNIX   MNIY   MNIZ    CWP      CWPLow   CWPH   NVtxs    WghtVtx   Annot
   1                2.015  134872    355.89           -36.3   -9.7       -1.4         0.96620  0.96390      0.96850    841     1298.68      insula
   2                1.652   71259    154.25           -49.4    -52.7       39.2      1.00000  -0.00010      1.00000    363      526.18      supramarginal
   3               -1.521   91550     39.92            -37.1  -26.5      -23.3        1.00000  -0.00010      1.00000     90     -125.33       fusiform
   4                1.322  139141      0.76           -36.4    3.5         -10.7       1.00000  -0.00010      1.00000      2        2.62          insula
   5                1.312   73658      0.47            -36.0   -4.4           9.6        1.00000  -0.00010      1.00000      1        1.31          insula
   6                1.387  133422      0.44             -5.1  -17.2        51.7        1.00000  -0.00010      1.00000      1        1.39          paracentral

I know CWP stands for Cluster-wise P-value. But what is the low and the high number, a confidence interval? And isn't it odd that my p-values are (almost) 1?

Thank you in advance.

Kind regards,

Rose
