My guess is that the download did not finish. To check that the file is
"correct" (i.e., that it is the same file with all of the same bytes as
the one that I have), check its exact size and md5sum. Here are the
results I get on my computer (which exactly match the values you are
told they should be on
http://ambermd.org/AmberTools14-get.html):
swails.batman /usr/local $ ls -l AmberTools14.tar.bz2
-rw-r--r-- 1 swails swails 212395464 Apr 17 12:34 AmberTools14.tar.bz2
swails.batman /usr/local $ md5sum AmberTools14.tar.bz2
589cc9bd17b15ce3f9604b0bdeea3bab AmberTools14.tar.bz2
So the tarball should be 212395464 bytes (203 MB) large with the md5sum
shown above. If it's not, something went wrong with the download, and
you should try again. Until your downloaded file matches the statistics
above, it will not work.
