When deleting data, it takes the server a short amount of time to
refresh. It may take a bit longer right now since many people are
performing this action at the same time.
For the RNA-seq analysis question, reference annotation GTF files are
used by the Cuff* programs. (These are different than the result GTF
files produced by the programs). For reference annotation GTF files,
there are many sources, including Ensembl and UCSC. Here are links to a
tutorial and an FAQ that can help with your usage question.
But, there are many small details to running the tools to get the
optimal results. These types of questions concerning functionality are
best directed to the tool authors at tophat.cufflinks(a)gmail.com

Well if I do , I do not know :-)
What I used is first TopHat and then Cufflink. At what stage shall I use
such a GTF file?
And additionnaly: where shall I find such a GTF file?
As I understand it: there are tow sources for a GTF file:
1. The output from cufflinks generates one (but there is no gene names in
2. I could get one from Ensembl?
Shall I then use Cuffcompare on the cufflink output?
