Hi, dock fans, I ran flexiable docking with dock6.1 and have ran into a problem below :
ERROR:  Could not complete growth. 
        Confirm grid box is large enough to contain 
        ligand and try increasing max_orients.

 
I read messages from :http://blur.compbio.ucsf.edu/pipermail/dock-fans/2006-August/000694.html , which said turning off the bump checking to fix the problem , but the problem is that I used "bump_filter   no" in my parameter file,  the following is the parameters I used . Is there something  wrong?
