Hi Martin and Beatriz,


I'm using SPHARM for interaction test in a group, but I'm a little confused with the test. First, please tell me if I'm doing it correctly. Here is one line of my glm matrix file :

1 1 /NAS/.../pat31_auto_lha_hippo_bin_close_to_templateSPHARM_ellalign.meta 66 1 11

I have 3 independent variables, age(66), gender(1) and my clinical score(11). I want to perform a correlation with the clinical score after a correction with age and gender, then I use : 

shapeAnalysisMANCOVA glm.txt --numIndependent 3 --interactionTest --testColumn 2

Is it correct ? I have no way to check if the correct variable is tested. 
Second, I'm confused with the results. I have correctly the Pearson and Spearman correlation statistics BUT, I obtain a map of FDR corrected p-value which correspond to the MANCOVA permutation. How is it possible given that I erform any group test ? What is the meaning of this p-value map of MANCOVA ?


Thank you for your help.
