Can you please help me interpret these results from FSL Nets ?

1. arone =

2. Here is another result, which is from the attached figure

sorted edge#1 nodes 7,4 value=0.997

What does this mean ? Does this value mean the p-value ?? But sometimes I get values around 0.62 for some nodes; while all the components used in the analysis were above 0.99 p value threshold after benferroni correction.

3. I m also not abe to understand the LDA percentages

[lda_percentages]=nets_lda(netmats3,19, 1) : FLD gives me

I m unable to understand the practical difference between these results; which one am I supposed to use ?

4. On the other hand 

[lda_percentages]=nets_lda(netmats3,19, 8) for libsvm gives me an error because the feature vectors in libsvm are mistakenly getting understood as group-names. 

svmstruct = svmtrain([ ones(size(xa,2),1) ; zeros(size(xb,2),1) ], [xa xb]' , '-q'); 

xa is 342x18 matrix. xb is 342x2 matrix. Can you please check and guide what to correct here ?

5. If I m trying to find the network differences between 2 groups; and given the clusters figure; what should I be able to interpret ? I can understand that these clusters represents how the good components are connected to each other based on the netmats method that I have used. But if I m looking to find network differences in two groups; how should I select the best netmats results on which this cluster figure is based upon ?? 

Any help will be highly appreciated

Thanks a lot and best,

Qasim
