>>> How to install ResQ?
    There are two steps to install ResQ:
    1) Download and unpack ResQ.tar.bz2 (available at: http://zhanglab.ccmb.med.umich.edu/ResQ/download/ResQ.tar.bz2)
    2) Download I-TASSER Suite (available at: http://zhanglab.ccmb.med.umich.edu/I-TASSER/download/)

>>> How to run ResQ?
    There are two methods to run ResQ depending on how your models were generated.
    1) If your models were generated by the I-TASSER Suite, you can run the script runResQ_IT.pl directly to predict B-factor and local structure errors. The only argument required is the directory of the I-TASSER decoys. You can read more at the head of this script to get more information about its input.

    2) If your models were not generated by I-TASSER Suite, you can run runResQ.pl without argument, which will print out the help information. In this case, ResQ needs to run the LOMETS program, which is available in the I-TASSER Suite.

>>> What is the output?
    For I-TASSER models, the output of ResQ (runResQ_IT.pl) is: rsq_bfp.dat
    For other models, the output of ResQ (runResQ.pl) is:
      1) global.txt for global accuracy estiamtion
      2) local.txt for local error and B-factor estimation
