Hi Liam, 

You cannot do this in the NBS software. 

But you can save the network from the first half and fit a model to each edge in this network using the second half data as part of a separate function that you would need to write. 

If you load in the second half data into NBS, it will perform statistical testing on this half. It is not possible to just compute coefficients. 

Best, 

Andrew

I want to conduct a split-half analysis using unpaired t-tests.

For the first half of the data, I conduct an unpaired t-test and find a network where the two groups are different. I extract the coefficient values from all first half data matrices and save the adj_edge_file.

I don't want to conduct another unpaired t-test on the second half of the data in the same way in NBS, as it is impossible to replicate. 

Instead, I just want to extract the coefficent values from the second half data matrices, but using the adj_edge_file that comes from the first half analysis.

I thought this would just be a simple case of loading the second half data matrices in NBS and then extracting the coefficient values.    

It doesn't do this, and just keeps giving me the coefficient values from all first half data matrices.

Is there a way of doing this in NBS, but that I am not getting right?

All the best, Liam.
