CONN functional connectivity toolbox: RRID SCR_009550, release 22

Abstract

CONN is a Matlab-based cross-platform software for the computation, display, and analysis of functional connectivity in fMRI (fcMRI). Version 22 brings a number of updates and additions to previous releases. Some of the main new procedures and tools include new interactive analyses exploring the entire brain-wide functional connectome, with a focus on descriptions of commonalities as well as heterogeneity of functional connectivity patterns across subjects and experimental conditions (similar to AFNI instacorr but across all subjects in a study; available in 2nd-level fc-MVPA summary tab), new preprocessing options for normalizing anatomical and functional volumes in the presence of anatomical lesions (available in Setup.Preprocessing), new displays for ROI-to-ROI connectivity and contingency table data (in ROI-to-ROI results explorer), as well as the ability to create automated text, distributed under a public domain dedication license, describing in detail the specific preprocessing, denoising, 1st- and 2nd- level analyses steps performed on each individual CONN project (available in Tools.WriteMethods).
