We present version 2.0 of piconmat.com, a freely-available web-based system for exploring connectivity strengths between cortical and subcortical regions in a database of individuals. Connectivity strength is computed using diffusion MRI and probabilistic tractography. Version 2.0 is a significant update: connectivity strengths are presented in an interactive connectivity matrix and controls allow the user to study connectivity in individuals who meet certain criteria (e.g., right-handed males aged 25-50), and connectivity strengths for individuals belonging to different groups can be visually and quantitatively compared (e.g., right-handed males vs. females).
