modularity index computation

[slipstick]

Hello,

The company I work for is now getting into the VI metrics analysis of our programs and I am struggling with the Modularity Index. According to the Style book, the value is computed by

# of VIs / total node count * 100.

In the image, I get a value with the calculator that varies from what the Analyzer reports. Can someone tell me how the Analyzer computes that value?

Hi Tay,

You are correct with the equation for the modularity index. I don't know why you are getting a modularity index of 0 for that vi. Could you post the vi for me to take a closer look?

Thanks!

Here you go...

Hi Tay,

I looked at your code and was unable to reproduce anything. Would you mind posting the code again with the project and with the vi analyzer task.

Thanks!

Here it is...

The VI Analyzer Results folder contains the config file and not results. Not my call on the name...

So I look at much more in depth and the problem is actually expected as the modularity index is subvi's/nodes and if there is no subvi's it is 0/X = 0.

Hope this helps.
