This is to let you know that a new resource is now available on JBrowse in Echinobase. This is a developmental series of ATACseq measurements for S. purpuratus embryos. In our experience and that of others focused on encoded genomic regulatory sequences, ATACseq data provide a vastly superior indication of the genomic location of putative cis-regulatory elements of all forms (see Buenrostro et al., Nature Methods 10, 1213–1218, 2013). The direct link is here.
A comparative repeat on a second timed batch of embryos will soon be posted, as will a similar set of observations on L. variegatus. The data included in this resource were created in our laboratory by Erika Vielmas, and were computationally reduced by Parul Kudtarkar at Echinobase, although of course the whole Echinobase team contributed essentially.
We shall presently submit for publication an analysis of various aspects of these data, including validation in respect to some known genes. We wanted this to be available for your use as soon as possible, however.
