    PR14 used 3 yeast PPI data to compare MCL with others. The MCL parameter was taken from Boheree2006. PR14 used protein complex as 'golden standard'. When overlapping score > 20%, MCL is the best algorithm. Bader's MCODE is also a good method for certain parameter settings.

    Xue 07, MSB, a modular network model of aging

    My notes on Xue 2007, a modular network model of aging.

    Xue07 examined PPI in fruit fly and human brain aging. Xue07 used simulation and stated that "aging might preferentially attack key regulatory nodes that are important for the network stability, implicating a potential molecular basis for the stochastic nature of aging".

    Xue07 identified negative (N) and positive (P) correlations during aging based on expression data, and then identified the PPI subnetwork for these NP correlations. Xue07 then used clustering method to identify 'network modules'.

    Its method paper is in
