Move it into an <h2>Data Access</h2> in the usual place, after Methods and before Credits, and add pointers to the Table Browser, the Data Integrator and the REST API, plus the maf* and bigWig* command line tools. 134 pages: 55 had a download block that was moved and labeled, 56 get a list built from hgdownload directories that were checked to exist, 21 have no download directory of their own and so get the Table Browser and API pointers only, and 2 already had a Data Access section that was reworked. Existing download lists are unchanged apart from http -> https and an added target="_blank". Wording follows what each track actually holds, so the alignment-only pages do not claim conservation scores and the Data Integrator is only mentioned where it can really be used, since it does not handle MAF. Also corrects one link: hg18 cons44way pointed at multiz44way/maf, which redirects; it is now multiz44way/maf/.

In full and pack display modes, conservation scores are displayed as a <em>wiggle track</em> (histogram) in which the height reflects the size of the score.

The predicted elements are segments of the alignment that are likely to have been "generated" by the conserved state of the phylo-HMM. Each element is assigned a log-odds score equal to its log probability under the conserved model minus its log probability under the non-conserved model. The "score" field associated with this track contains transformed log-odds scores, taking values between 0 and 1000. (The scores are transformed using a monotonic function of the form a * log(x) + b.) The raw log odds scores are retained in the "name" field and can be seen on the details page or in the browser when the track's display mode is set to "pack" or "full". </p> +<h2>Data Access</h2> +<p> +The alignments and the conservation scores can be retrieved for a single region or for a list of +regions with the <a href="hgTables?db=fr3&hgta_group=compGeno&hgta_track=cons8way">Table +Browser</a>, which returns the alignments in MAF format and the scores as wiggle data.
