You can use wb_command -cifti-parcellate on the dense timeseries to get the timeseries and then wb_command -cifti-correlation to get the network matrix. Spatial ICA and areal parcellations are in some ways different approaches to dimensionality reduction of the data.

Now I have HCP lifespan rfMRI time series data. I want to do network analysis. I want to extract time series associated with every functional ROI, which are nodes of the network. Which connectome workbench command should I use? And, there are many voxels corresponding to a ROI, how do I deal with them to get a time series corresponding to a ROI? Or, I can use ICA components ,each of which has a time series, as nodes of the network? In this case, how should I define ICA dimensionality, so I can think of each component as a node, not a network? Thanks. 发件人: Glasser, Matthew [mailto:[email protected]] 发送时间: 2017年5月26日 0:23 收件人: wtj <[email protected]<mailto:[email protected]>>; [email protected]<mailto:[email protected]> 主题: Re: [HCP-Users] BOLD signal The database is back up and you can get the parcellation from here: https://balsa.wustl.edu/file/show/3VLx Peace, Matt.
