# optimal branch specific model

## OBSM

Introduction:

OBSM is a pipeline calculate Optimal Branch Specific Model with CODEML (belong to PAML package). It is written by Perl. OBSM will calculate a bunch of branch model based on Dynamic Programing prediction. Accoridng to our analysis, OBSM will logically find out the optimal model--in 50 cases we recalculate, OBSM find out much better models in 47 times, while the remain 3 times are the same model compare to the previous study.
