NAME PPSampler2 (Proteins' Partition Sampler Version 2) - predicts protein complexes from weighted protein-protein interactions SYNOPSIS PPSamplers [OPTIONS] OPTIONS -f, --file specify a file of protein-protein interactions (PPIs) with their weights, where each line should contain two protein IDs and the corresponding interaction weight, which are tab-deliminated. Optionally, three files of PPIs with weights for protein complexes of size two, three, and four or more can be specified in the format of fileOfSize2;fileOfSize3;fileOfSize4OrMore. -h, --help show help document and exit. --output set an output file to be . The default is "output.txt" in the working directory. --maxClusterSize set the possible maximum size of clusters to be predicted to be . The default is 100. --temperature set the temperature parameter to be . This parameter controls acceptance rate of candidate state. The default is 1e-9. --gamma set the parameter, gamma, of the score subfunction, f_2, to be . The default is 2. --f1DenominatorExponent set the exponent of the denominator of f1(c), where c is a cluster, to be . The default is 0.5. --f2 add the function, f2, into the whole scoring function, f. Without this option, f2 is not included in f. In the default, this option is not valid. --f2variance1 The variance of f2 is /^(cluster size), where is specified by the next option, --f2variance2. The default is 1000. --f2variance2 see the above. The default is 1.1. --lambda set the parameter, lambda, of the score subfunction, f_3, to be . The default is 2000. --f3variance set the variance of f3 to be . The default is 1e6. --maxIterationCount set the repeat count to be . The default is 2e6, in which case, PPSampler2 will stop in 20 minutes. --proposalDitribution specify a proposal distribution. is either 1 or 2. The option of 1 corresponds to the proposal distribution given in [1]. The option of 2 is the modification of the former one, which is explained in [2]. This is more efficient in time than the former. We recommend to use the option of 2. The default is 2. --beta set the parameter, beta, of both proposal distribuitions. should be in [0..1]. The default is 0.01. --noPlot makes no graphs of historical scores. Without this option, graphs are given. -v, --version output version information and exit.
