I thought I had replied to this, but don't see it any where in my sent
folder. So, please forgive me if this is the second time I have sent this.
The PickleCol works great. It is a neat idea and it does exactly what I
need in this situation. But the files are very large. SciPy has a
function called shelve and using it to store the same data seems to
result in files about 1/10th the size of using PickleCol and matrices.
I think shelve uses some sort of compression or something. Is there
away to use compression with PickleCol?
