Figure 4

Author/co-authorship graphs for nine pilot centers of the Protein Structure Initiative. Publications were collected from the official publication lists of the following centers: Berkeley Center for Structural Genomics (BSGC), Center for Eukaroytic Structural Genomics (CESG), Joint Center for Structural Genomics (JCSG), Midwest Consortium for Structural Genomics (MCSG), Northeast Structural Genomics (NESG) consortium, New York Structural Genomics Research Consortium (NYSGXRC), Southeast Consortium for Structural Genomics (SECSG), Structural Genomics of Pathogenic Protozoa (SGPP), and Tuberculosis Structural Genomics (TB) consortium. The MCSG, NESG, and NYSGXRC consortia have comparably greater authorship of publications, with individual laboratories clustering together. The BSGC and JCSG centers include nearly all participating authors on every publication, as seen by dense clusters with heavy edge weights. At the other extreme, the TB consortium is a loose collaboration of many groups of different scientists who tend to publish separately.
