ANGLOR for backbone dihedral angle prediction
                         version 1.0 written by Sitao Wu


INSTALL THE SOFTWARE:
1. uncompress ANGLOR_source.tar.bz2 to a directory like xxxx/ANGLOR_source.
2. change path settings of xxxx/ANGLOR_source/library/bin/psipred24/runpsipred:
      dbname=xxxx/ANGLOR_source/library/data/nr/nr.filter
      ncbiname=xxxx/ANGLOR_source/library/bin/blast/bin
      execname=xxxx/ANGLOR_source/library/bin/psipred24/bin
      dataname=xxxx/ANGLOR_source/library/bin/psipred24/data
3. change the setting of xxxx/ANGLOR_source/ANGLOR/ANGLOR.pl:

      $datadir="xxxx/ANGLOR_source/example/$pdb"; #Phi and Psi prediction are saved in
                                                  # "xxxx/ANGLOR_source/example/$pdb"
      $libdir="xxxx/ANGLOR_source/library"; #ANGLOR libary
      $bindir="xxxx/ANGLOR_source/library/bin"; # Directory of ANGLOR executalbe files
      $user="username"; # Your user name

HOW TO RUN THE SOFTWARE:
Suppose the sequence file is saved in xxxx/ANGLOR_source/example/e01/seq.txt. First 
change current directory to xxxx/ANGLOR_source/ANGLOR. Then type:
"./ANGLOR.pl e01".
After the prediction is finished, the phi and psi angle predictions are saved in
"xxxx/ANGLOR_source/example/$pdb/phi.txt" and "xxxx/ANGLOR_source/example/$pdb/psi.txt"
respectively.
