I have recently begun to use DOCK 5.2, and at the moment I am encountering a 
rather irritating problem. Specifically, when I attempt to run dock itself 
using one sphere file I have generated, the program runs smoothly and I 
obtain a nice set of docked orientations. When I use a different sphere file 
I have generated (which has more spheres within the cluster, but is 
otherwise identical as far as I can tell), there is a segmentation fault. 
I've implemented bugfix #9, and the sphere file itself has only 1 cluster 
and the proper number of spheres listed on the top. I've attempted to paste 
the text into a new file from Word, in case there were hidden characters, 
but that had no effect. The only other possible issue is that the file 
contains 314 spheres, but I was under the impression that it was only 
recommended to keep the number of spheres below 100 for performance reasons. 

In any event, I can enclose the .sph file if that would assist in diagnosis, 
but I will wait for some response first, in case there may be an obvious 
problem that I'm missing (And to avoid spamming the group on my first post
