[Bioperl-l] How to use gi2taxonid

[Hubert Prielinger]

hi,
I have downloaded the gi2taxonid file to get the taxonid for a GI number 
taken from a report as recommended here, but I don't know how to use the 
gi2taxonid file.
Jason wrote in a previous post that you have to make a DB_File out of 
it, but I don't know how....and finally tie it to a hash....
Can anybody give me a hint how to use it..... my final goal is to get 
the taxonomy.

thanks
Hubert
