[Pytables-users] Change data already in PyTables array

[Sigve T. <sig...@3d...>]

Is there a method to change the data in a PyTables array / earray? I want 
to save a large array of data to disk, and then change only parts of it 
after some processing. Is this possible with PyTables or is arrays 
essential write once, read many? If there were a memory mapped array slice 
similar to the one provided by NumArray, it would do the trick, but I have 
not located such a feature.

Best regards, Sigve Tjora
