I am using hgWiggle without a database to pull phastCons scores for a given 
chromosome position. It seems to be working pretty well using the following two 
wib and wig files downloaded from here:

ftp://hgdownload.cse.ucsc.edu/gbdb/hg19/multiz46way/phastCons46way.wib
ftp://hgdownload.cse.ucsc.edu/goldenPath/hg19/database/phastCons46way.txt.gz

... using the set-up with the instructions from here:
http://genomewiki.ucsc.edu/index.php/Using_hgWiggle_without_a_database

However, the only concern I have is that running hgWiggle without a database 
with these two files is slow, which I suspect is from the size of the wib file 
listed above and nearly 3 GB.   I have noticed that there are *.wigFix files 
for each chromosome listed here:

ftp://hgdownload.cse.ucsc.edu/goldenPath/hg19/phastCons46way/vertebrate/chr**.phastCons46way.wigFix.gz

and so I was wondering... a) are there are associated *.wib files for these 
individual chromosome files, b) is it possible to run hgWiggle using these 
chromosome-specific *.wigFix files, and c) do you think it would be faster to 
use the smaller, chromosome-specific files rather than the larger 
phastCons46way files I am currently using?  If not, I suspect using the actual 
database with hgWiggle would be significantly faster, but I'm not entirely 
excited or confident about trying to get a local copy of the database up and 
running on my computer.  Is there a set of instructions on getting the database 
up and running locally?

Thanks,
Craig
