Great! Thank you! I will dive into that :)

Hi - OK, this is easy - use group-ICA and then dual-regression and then FSLNets

Cheers.

Hi Steve,
Sorry for being not clear. We want to do the same as is in the Fox (2005) paper: http://www.ncbi.nlm.nih.gov/pubmed/15976020
But instead of correlating time courses of task-positive regions with those of task-negative regions, we want to correlate complete networks: so for example the frontoparietal network with the default mode network.
We then want to investigate whether this degree of (anti-)correlation changes over time.
So, I am thinking of a way to correlate time courses of two networks.

Hi - I think you need to start with a much clearer definition of what question you are wanting to ask - it's not very clear what you mean by "correlate two resting state networks".
Cheers, Steve.

Dear FSL developers,
For our next project we want to correlate two resting state networks , so two different components from the ICA.
I have been thinking on what would be the best way to do such an analyses, and I was thinking to calculate the mean of the time courses of one component and use that as a voxel-based EV in the design.
I thought I could then analyze the association between this voxel-based EV component and the other component by using the GLM gui.
So set the contrast as 0 1.
Would it be possible to extract correlation coefficients?
Would that be the solution? Or are there other more intelligent ways to investigate this?
Look forward to your suggestions!
