Dear experts,

I recently started to use CONN and got a few questions about the analysis in this toolbox.

In particular, I am not sure about how the  weighted GLM works in functional connectivity analysis.

Now I'm guessing one possible scenario: the condition vector, which is made from the conditions in the 'SETUP', multiplied with the BOLD timeseries in order to make unrelated BOLD signal to zero.

Is it the real process using weighted GLM in 1st-level analysis?

If it is right, I'm not sure how to get bivariate correlation coefficient using that timeseries. Does the toolbox remove the zero points and calculate the correlation?

Thanks!
