Protein Design


We developed a protein design algorithm that selects the final designed sequences from clusters of low-free-energy decoy sequences.

Sequence clustering program
CLUSEQ is a program to cluster a set of amino acid sequences based on their BLOSUM62 similarity.
  INSTALLATION (Linux)
  1. cd to the directory where you want to install the program.
  2. Download and unpack "cluseq.tar.gz" into the installation directory.
  3. Change the path to input file "blosum62.txt" in source file "cseqlongset/Amino1CharSeq.cpp" (line 6). 
     The path must be changed to the location you choose for "blosum62.txt" in your file system.
  4. Run the "build" script from the installation directory.
  5. You are ready to run CLUSEQ.
 
  USAGE
  cluseq <path_to_the_input_file>
  - The input file (example) contains the set of amino acid sequences to cluster. 
    The sequences are all of the same length and occupy consecutive lines in the file. 
    Each sequence lies on a single line and is immediately followed by a line terminator.
  - The output (example) is printed to screen. First it lists the cluster centers (tags), then it lists
    the entire clusters. The clusters are expressed in terms of sequence indices in the input file. 
    Both the sequence indices and the cluster indices start at 0. Cluster 0 is the largest cluster. 
    The first index of each cluster represents the tag of the cluster.
