Good Afternoon Dr. Bina:
Your error appears to be from a file transfer that did
not complete properly.
Does the file look like this in size:
$ ls bosTau8.fa.gz
-rw-rw-r-- 1 868105036 Oct 21 2014 bosTau8.fa.gz
With sum:
$ md5sum bosTau8.fa.gz
46a577bb922a261988471842fec7779d bosTau8.fa.gz
Which compares to the sum in md5sum.txt
$ grep bosTau8.fa.gz md5sum.txt
46a577bb922a261988471842fec7779d bosTau8.fa.gz
This will transfer the file more efficiently than FTP:
rsync -a -P rsync://
hgdownload.cse.ucsc.edu/goldenPath/bosTau8/bigZips/bosTau8.fa.gz ./
