Where should I extract library files?

I a nut shell: should it be
~/HomeI-TASSER/nr/nr/some.file or ~/HomeI-TASSER/nr/some.file
?

Hello,
I just installed I-TASSER on Ubuntu and I am trying to run a test sequence. The output doesn't look good (see the end of the post).The same error was described in this post:
http://zhanglab.ccmb.med.umich.edu/bbs/?q=node/130

I have checked "the path of your PSIBLAST executable: /home/mcho/I-TASSER/blast/bin/blastpgp" . Yes, the path is correct.

I think, the problem comes from the step "4.2. Files needed to download and install" of the manual. I think that I extracted them in a wrong place. For example, right now I have a directory ~/Home/I-TASSER/nr in this folder I have folders
nr
nr.00
nr01
..
nr05

In turn nr01 folder contains
nr.01.phd
nr.01.phi
..
nr.01.seq

So, what path for extracted files is correct
~/HomeI-TASSER/nr/nr/some.file or ~/HomeI-TASSER/nr/some.file

If the answer is "correct path is ~/HomeI-TASSER/nr/some.file" then where should the nr.00 - nr.05 files go?

what about *.sig files? Should it be
~/HomeI-TASSER/SIG/SIG/*.sig or ~/HomeI-TASSER/SIG/SIG/*.sig ?

Thanks in advance.
Stepan
