forgot once more than probesets are usually on hg19, not hg38, adding a note for myself to the docs page. Also adding a note that avada has been lifted to hg38. no redmines.

 Tracks labeled as <em><b>Probes (P)</em></b> indicate the footprint of the oligonucleotide probes
 mapped to the human genome. This is the technically relevant targeted region by the assay. However, 
 the sequenced region will be bigger than this since flanking sequences are sequenced as well.  
 Tracks labeled as <em><b>Target Regions (T)</em></b> indicate the genomic regions targeted by the
 assay. This is the biologically relevant target region. Not all targeted regions
 will necessarily be sequenced perfectly; there might be some capture bias at certain locations.
 The Target
 Regions are those normally used for coverage analysis.

+<p>Note that most exome probesets are available on hg19 only. If you are working with hg38 and cannot find
+a particular probeset there, try to go to hg19, configure the same track, and
+see if it exists there. If you cannot find an array, do not hesitate to send us
+an email with the name of the manufacturer website with the probe file.  If
+an array is available on hg19 but not on hg38 and you need it for your work, we
+can lift the locations. Our mailing list can be reached at genome@soe.ucsc.edu.

 <h1>Methods</h1>
 
 <p>
 The capture of the genomic regions of interest using <b>in-solution capture</b>, is achieved 
 through the hybridization of a set of probes (oligonucleotides) with a sample of fragmented genomic 
 DNA in a solution environment. The probes hybridize selectively to the genomic regions of interest 
 which, after a process of exclusion of the non-selective DNA material, can be pulled down and 
 sequenced, enabling selective DNA sequencing of the genomic regions of interest (e.g., exons).
 In-solution capture sequencing is a sensitive method to detect single nucleotide variants, 
 insertions and deletions, and copy number variations.
