Dear Experts,
I completed my FA group analysis and I expect my FA to be larger in controls versus patients (based on the uncorrected results). I corrected by multiple comparisons using:
mri_glmfit-sim \ --glmdir GroupAnalysis_pos.glmdir \ --sim perm 1000 3 permcsd \ --sim-sign pos \ --cwpvalthresh .05
so I have my:
permcsd.sig.cluster.nii – map of significance of clusters permcsd.sig.ocn.nii and grf.th3.pos.sig.ocn.lut – segmentation of significant clusters permcsd.sig.cluster.summary – text file of cluster table (clusters, sizes, MNI305 XYZ, and their significances)
1) How can I visualize my results more exactly how I can visualize my uncorrected and corrected results. 2) How I can output in a table the FA values corresponding to each cluster? 3) If use tkmedit is the Functional value given me the FA values while moving the cursor or this Functional value represents something else in the case I plot:
tkmedit cvs_avg35 norm.mgz \ -ov /media/2Tra/Antonella_2011/DTI_FS/GLM_CVS/GroupAnalysis_pos.glmdir/contrast/permcsd.sig.cluster.mgh \ -seg /media/2Tra/Antonella_2011/DTI_FS/GLM_CVS/GroupAnalysis_pos.glmdir/contrast/permcsd.sig.ocn.mgh \ /media/2Tra/Antonella_2011/DTI_FS/GLM_CVS/GroupAnalysis_pos.glmdir/contrast/permcsd.sig.ocn.lut \ -fthresh 0.2 -fmax 1
Thank you very much, Antonella
