Hello,
I'm having a problem with PyTables that's driving me nuts. I'm probably doing
something wrong, but I wonder if it could be a bug.
Basically, I need to write a series of numpy arrays to an HDF file. Because of
performance and compression requirements, I decided to convert each numpy array

Hi All!!
I'm quite new to pytables and this mailing list so I'm sorry if my
question is a bit stupid!:)
I'm using pytables to buil a persistent binary tree containing from
10^3 to 10^8 (may be in future 10^10) integer numbers. The structure
reflects a previus binary tree entirely built in memory.
