A Question Regarding Connectivity Threshold

[maede...@gmail.com]

Dear frank

In the process of calculating connectivity matrices, I set the connectivity threshold to dsi studio's default which is 0.001 of the maximum value.

Now I have been asked to cite a reference, because they believe that 0.001 of the maximum value may exclude true positives as well. 

Now I wonder, of which base  its default value is 0.001?Actually, searching the papers that have done connectivity-based study using deterministic tractography, I havent been able to find a reference so far.

I would be grateful if you could  help me justify or find a reference.

best regards

Maedeh

It depends entirely on the data, and you may figure out the best threshold.
Sorry I don't have a reference.
