GraphVar group1 vs. group2

Dear Tetsuya,

this seems strange and should not happen. I tried to replicate what you describe but I get the same results as in the results viewer when I extract the data. To make sure we really talk about the same thing this is what I did with the sample data from the sample workspace:

1. load all 30 subjects

2. calculate a group difference between male and female in the raw matrix on the connectivity between Precentral_L and Precentral_R

3. the contrast Group(female)<Group(male) should result in a difference of 0.044 (which means that males have a higher connectivity)

4. now extract the respective cells in the sample connectivity matrices for Precentral_L and R and plot these according to the subject in e.g. in the variable sheet

5. If I now manually calculate the group difference in connectivity from the extracted values (males-females) I get exactly the same difference of 0.044, telling me that males>females (as in the results viewer)

6. I did the same with smallworldness and the weighted clustering coefficient (calculate end export via the "calculate and export" button in the network calculations panel) and also manually run a group comparison. Again, the results mirror the results from the results viewer. At least for the weighted clustering coefficient it is also males>females with a positive difference of 0.02 at threshold .048 (as smallworldness is claculated from random networks our results could differ, but for me it is also males>females with a difference of 0.02).

Please try this out to see if you get the same results as I do - if you get the same results, results from your analysis (with other data) should also be correct.

Let me know what comes out!

Johann

Best wishesDear Johann,

Hi

I am trying to analysis my data including 35 subjects with group comparison, I used the mutual information to create the graphs but I have serious problems with following sample settings. I was wondering if you could help me.

Best wishes
