 To test this toolbox and generate a protein-specific genome-scale model you just need to run humanSec.m function. This function needs following inputs:
   1) A model (HMR2 or HMR2-drived models)
   2) Uniprot ID for your interested protein
-  3) Protein-Specific Information Matrix (there is a list of human proteins in excel format in repository named PSIM_HUMAN.xlsx). you can call this list using importPsimFromExcel.m function and then use it in humanSec.m function.
-  4) List of template reactions (there is a list of template reactions in excel format in repository named tempRxns_v01.xlsx). you can call this list using importTempRxnsFromExcel.m function and then use it in humanSec.m function.
