PI is a program for interpreting MS/MS data,
whose performance has been tested over three public datasets which from A8_PI, Gygi and Keller.

A8_IP This is the experiment results on A8_IP data set, which includes the training set, the testing set and the parameters to loss a NH3 or a H2O.
PI_package This is a PI package for download, which includes the source code package and a jar file.
Experiment_Result_On_Keller_Data This is the experiment results on Keller's data sets.
SEQUEST_IONTRAP This is the experiment result on the of SEQUEST runned on Gygi LTQ data.
SEQUEST_QSTAR This is the experiment result on the of SEQUEST runned on Gygi QSTAR data.
