[Genome] fly assembly sequence

[Debasis Dan]

Hello,
   While using multiple alignments from goldenPath/dm2/multiz15way/ 
directory I find that
some of the recent version of sequences like D. pseudoobscura (dp4, Feb. 
2006), D. ananassae (droAna3, Feb. 2006) that have used to make this 
multiple alignment are missing from the 
http://hgdownload.cse.ucsc.edu/downloads.html page. Can you direct me to 
the page where I can find these versions of scaffolds/chromosomes in 
fasta format ?
    I look forward to your early reply.

With warm regards,
Debasis Dan
