[Genome] 1 maf file in addition to individual maf files

[Hiram Clawson]

Good Morning Howard:

For the large multiple alignments, a single maf file becomes too
large to be practical.  Files larger than several Gb cause a variety
of difficulties.

I would recommend using rsync to download data from hgdownload with
no need to worry about the number of files:

For example, the 28-way multiple alignment on hg18 can be fetched
with the rsync:

rsync -avz --progress rsync://hgdownload.cse.ucsc.edu/goldenPath/hg18/multiz28way/ ./

Resulting in about 26 Gb of data transferred.
