[[FsTutorial/GroupAnalysis|Back to Group Analysis]] Surface-based Cluster Summary Table as created by mri_glmfit-sim. 1. Lines that begin with '#' are comments 1. Each data line is a cluster 1. There are 38 clusters 1. The value in the first column is the cluster number, which allows linking to the annotation. 1. Max indicates the maximum -log10(pvalue) in the cluster 1. VtxMax is the vertex number at the maximum 1. Size - surface area (mm^2) of cluster 1. Tal(XYZ) is the talairach (MNI305) coordinate of the maximum 1. CWP - clusterwise p-value. This is the p-value of the cluster 1. CWPLow and CWPHi - 90% confidence interval for CWP 1. 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. {{{ Cluster Growing Summary (mri_surfcluster) # $Id: mri_surfcluster.c,v 1.57 2014/03/06 17:02:46 greve Exp $ # $Id: mrisurf.c,v 1.778 2016/02/03 18:58:39 fischl Exp $ # CreationTime 2016/03/18-19:41:27-GMT # cmdline mri_surfcluster.bin --in lh.gender_age.glmdir/lh-Avg-thickness-age-Cor/sig.mgh --csd /home/nmrclass/freesurfer/average/mult-comp-cor/fsaverage/lh/cortex/fwhm14/neg/th40/mc-z.csd --mask lh.gender_age.glmdir/mask.mgh --cwsig lh.gender_age.glmdir/lh-Avg-thickness-age-Cor/cache.th40.neg.sig.cluster.mgh --vwsig lh.gender_age.glmdir/lh-Avg-thickness-age-Cor/cache.th40.neg.sig.voxel.mgh --sum lh.gender_age.glmdir/lh-Avg-thickness-age-Cor/cache.th40.neg.sig.cluster.summary --ocn lh.gender_age.glmdir/lh-Avg-thickness-age-Cor/cache.th40.neg.sig.ocn.mgh --oannot lh.gender_age.glmdir/lh-Avg-thickness-age-Cor/cache.th40.neg.sig.ocn.annot --annot aparc --csdpdf lh.gender_age.glmdir/lh-Avg-thickness-age-Cor/cache.th40.neg.pdf.dat --cwpvalthresh 0.05 --o lh.gender_age.glmdir/lh-Avg-thickness-age-Cor/cache.th40.neg.sig.masked.mgh --no-fixmni --bonferroni 2 --surf white # cwd /home/nmrclass/freesurfer/subjects/tutorial_data/buckner_data/tutorial_subjs/group_analysis_tutorial/glm # sysname Linux # hostname nmrclass19 # machine x86_64 # FixVertexAreaFlag 1 # FixSurfClusterArea 1 # # Input lh.gender_age.glmdir/lh-Avg-thickness-age-Cor/sig.mgh # Frame Number 0 # srcsubj fsaverage # hemi lh # surface white # group_avg_surface_area 82220 # group_avg_vtxarea_loaded 0 # annot aparc # SUBJECTS_DIR /home/nmrclass/freesurfer/subjects/tutorial_data/buckner_data/tutorial_subjs/group_analysis_tutorial # SearchSpace_mm2 65416.6 # SearchSpace_vtx 149953 # Bonferroni 2 # Minimum Threshold 4 # Maximum Threshold infinity # Threshold Sign neg # AdjustThreshWhenOneTail 1 # CW PValue Threshold: 0.05 # Area Threshold 0 mm^2 # CSD thresh 4.000000 # CSD nreps 10000 # CSD simtype null-z # CSD contrast NA # CSD confint 90.000000 # Overall max 3.74095 at vertex 153106 # Overall min -11.5636 at vertex 134036 # NClusters 20 # Total Cortical Surface Area 65416.6 (mm^2) # FixMNI = 0 # # ClusterNo Max VtxMax Size(mm^2) MNIX MNIY MNIZ CWP CWPLow CWPHi NVtxs WghtVtx Annot 1 -11.564 134036 3685.09 -11.1 34.5 27.2 0.00020 0.00000 0.00040 8495 -46427.05 superiorfrontal 2 -11.479 136827 7353.19 -49.4 5.9 -16.9 0.00020 0.00000 0.00040 18945 -105891.25 superiortemporal 3 -9.462 38853 1414.27 -25.4 -75.9 18.6 0.00020 0.00000 0.00040 3450 -18026.77 superiorparietal 4 -8.836 38022 150.27 -27.5 28.3 2.1 0.00280 0.00180 0.00380 408 -2297.87 lateralorbitofrontal 5 -8.379 95475 1068.72 -20.6 -49.4 -2.3 0.00020 0.00000 0.00040 2549 -13274.34 lingual 6 -8.323 133346 445.15 -33.0 -36.8 37.5 0.00020 0.00000 0.00040 1684 -8583.54 supramarginal 7 -8.081 101082 329.73 -44.4 -50.4 9.2 0.00020 0.00000 0.00040 984 -4973.56 bankssts 8 -7.915 120330 402.71 -20.2 -66.9 24.4 0.00020 0.00000 0.00040 1025 -4941.69 precuneus 9 -7.409 10899 413.74 -12.1 -54.9 28.8 0.00020 0.00000 0.00040 1050 -5410.59 precuneus 10 -6.724 155919 341.74 -56.8 -38.8 40.2 0.00020 0.00000 0.00040 1175 -5467.80 supramarginal 11 -6.583 120934 494.68 -27.6 -79.9 -8.1 0.00020 0.00000 0.00040 1075 -5092.23 fusiform 12 -6.567 80571 208.72 -31.2 34.1 25.6 0.00020 0.00000 0.00040 491 -2320.33 rostralmiddlefrontal 13 -5.987 62853 260.64 -52.0 -49.3 -19.0 0.00020 0.00000 0.00040 514 -2449.65 inferiortemporal 14 -5.577 81545 156.62 -28.8 -39.1 51.2 0.00260 0.00180 0.00360 487 -2192.27 superiorparietal 15 -5.389 159131 242.49 -10.4 -43.9 41.1 0.00020 0.00000 0.00040 655 -2765.41 precuneus 16 -5.248 81927 84.70 -9.1 -21.2 59.9 0.02938 0.02642 0.03253 207 -906.86 paracentral 17 -4.646 108705 84.31 -30.5 -55.0 62.5 0.03017 0.02702 0.03332 277 -1134.21 superiorparietal 18 -4.563 63135 73.74 -33.4 -43.5 -15.9 0.04273 0.03901 0.04645 124 -509.13 fusiform 19 -4.370 35855 194.37 -62.8 -44.5 -4.4 0.00040 0.00000 0.00080 551 -2199.50 middletemporal 20 -4.281 33706 89.60 -36.1 -72.7 43.9 0.02623 0.02326 0.02918 261 -1029.40 inferiorparietal }}}
