Graph-theory in conn
Hello conn users,

I've never worked with conn before and now I am trying to use it for a graph-theory analysis of resting state data.
The software is a bit overwhelming and the PDF manual seems geared towards task-based data, so any help would be appreciated!

(This thread helped somewhat: http://www.nitrc.org/forum/message.php?msg_id=4678 )

The following input data is used:

(1) one participant's resting-state fMRI (128 time points, 2s TR) in MNI152 space (2mm)
(2) MNI152T1 as the structural image
(2) ROIs (GM, WM, CSF) obtained by segmenting the MNI152 T1
(3) BA ROIs that come with conn (these are intended to be used for computing graph-theory measures)
(4) condition: "rs", onset: 0, duration: 256
No covariates, 0.01-0.08 band pass filtered, WM and CSF masks used to define GLM confounds in "Preprocessing"

After all is said and done, the output doesn't look right:
