Surface-based Cluster Summary Table as created by mri_glmfit-sim.
- Lines that begin with '#' are comments
- Each data line is a cluster
- There are 38 clusters
- The value in the first column is the cluster number, which allows linking to the annotation.
- Max indicates the maximum -log10(pvalue) in the cluster
VtxMax is the vertex number at the maximum
- Size - surface area (mm^2) of cluster
- Tal(XYZ) is the talairach (MNI305) coordinate of the maximum
- CWP - clusterwise p-value. This is the p-value of the cluster
- CWPLow and CWPHi - 90% confidence interval for CWP
- NVtxs - number of vertices in cluster (each vertex will not have the exact same area, you can estimate mean vertex area by dividing total surface area by the number of vertices)
Eg, the 13th cluster has a pvalue of p<.006.
