#This is the extracting features proccess for MIALAB-PPIP, which can compute features for the prediction of residue-residue interaction.

There is no installation needed, just make sure the following files are included:
(1) extract_features.sh
(2) hydro.txt
(3) classify_features_by_chain.sh
(4) extract_surface.sh
(5) classify_surface_by_chain.sh
(6) README.md

After installation and before running computing jobs,The following externel sofeware tools is required:
(1) Qcontacts		
(2) Naccess
(3) Propka31

(1)Please change directory to MIALAB-PPIP cd /MIALAB-PPIP (2)Please put the ".pdb" data which you want to extract their features in a directory called "pdb" mkdir pdb (3)Please create a directory called "data" and copy the directory "pdb" mkdir data cp -r pdb data (4)Please change directory to /home/username/MIALAB-PPIP.Then execute: nohup bash extract_features.sh & (5)If you want to classify the data by protein chain, then execute: nohup bash classify_features_by_chain.sh &

A directory "results" which contains "features_by_chain" & "features_by_pair" will be created after the compute jobs running out.

If you running the (5) of Usage, then you will get serveral directory by chain.
