This was already using the smaller uniprot_spot.dat file rather than
the larger uniprot_trembl.dat, see:


We could include the links to the current release and to a specific

The tutorial was mean to get you to download all the chunks (16 at time
of writing), but I like your idea about picking a record near the start
so this can be done with just the first few chunks. Already logged as
