RE: How can I generate a ROI-configuration file based on ICA results?
Hi Dora,
To manually create an ROIconfiguration file you may use something like the example below:
network1 = {atlas.'IC l', 'atlas.IC r'};
network2 = {'atlas.AG l', 'atlas.AG r'};
network3 = {'atlas.pMTG l', 'atlas.aMTG l','atlas.aMTG r','atlas.pMTG r'};
conn_roiclusters( {network1, network2, network3}, {}, {}, {'Insular Cortex','Angular Gyrus','Middle Temporal Gyrus'} );
and that will create a file named 'ROIorder.mat' defining the above networks, which you can then load/import in the ROI-to-ROI results explorer window (in any conn project where the above ROIs are defined) in order to analyze the within- and between- network connectivity patterns using the 'Functional Network Connectivity' approach (see https://web.conn-toolbox.org/fmri-method... more details about the FNC approach used in CONN, and see 'doc conn_roiclusters' for more details about how to create your own ROIconfiguration files)

Hi!
I would like to create a ROI-configuration file manually, based on the results from an ICA analysis on datasetA.
I have an anatomical atlas file, where ROIs represent the brain regions.
From the results explorer, I extracted how many voxels are covering what percentage of the respective ROIs of this atlas for each ICA network.
So I have the information that e.g. network A contains ROI x,y,z
My goal is to do a ROI to ROI analysis on datasetB, where I can use hierarchical clustering utilizing this information. How could I manually create the necessary ROIconfiguration.mat file? Based on this hierarchical clustering, could I also analyse the relationship between network A and network B if both contain multiple ROIs?
Thank you,
Dora
