Hi,

After indexing I got files. I need to use .bwt file and .sa file in my algorithm.

My question is: is there a way to decompress .bwt file and .sa file ?

I tried zlib.decompress it doesn't work.

Any help will be appreciated.

But why would you want to do that?

It's also not just a compression, it's a suffix array/transformed/indexed genome.

I need to use BWT and SA in my algorithm that why I need to decompress them because in the first step to produce BWT and SA: we have to form all rotations. All these rotations took too much memory that why I prefer to produce BWT and SA by using BWA. Any idea how to use BWT and SA ? Or what is the best way to produce BWT ? better than the naive version of the BWT that forms all rotations.

Hello mrm259!

This is typically not recommended as it runs the risk of annoying people in both communities.
