[EMBOSS] dbxflat and size of index files

[Jérôme Laroche]

Hello,

I use dbxflat to index uniprot (sprot and trembl) flat files for  
which the size is 1.2 G for sprot and 11 G for trembl. The resulting  
files are amazingly huge: 11 G. Is it normal?

Another example with Genbank flat files: the division gbsts has a  
size of 3.3 G. Indexing with dbxflat give 6.8 G of index files but  
with dbiflat give only 199 M of index files. I know its not necessary  
to index genbank flat files with dbxflat because each individual file  
is not bigger than 300 M. I did this just for the demonstration.

Apart of this, all is working very well.

Thank you in advance.
