ASTRAL-SCOPe subset 2.04 in ActivePapers format

<p>This ActivePaper contains the structures in version 2.04 of the&nbsp;ASTRAL SCOPe subset with less than 40% sequence identity. For more&nbsp;information about ASTRAL and SCOPe, see</p> <p>&nbsp; http://scop.berkeley.edu/astral/</p> <p>Each ASTRAL entry describes a domain from a protein structure in the&nbsp;PDB. This ActivePaper contains these domains in the MOSAIC HDF5&nbsp;format. For more information about MOSAIC, see</p> <p>&nbsp; http://mosaic-data-model.github.io/</p> <p>The structures are arranged by its SCOPe classification. For example,&nbsp;ASTRAL entry d1v0aa1 is found under /data/b/18/1/30/d1v0aa1, because&nbsp;SCOPe classifies it&nbsp;as</p> <p>&nbsp; b: all-beta proteins<br /> &nbsp; b.18: Galactose-binding domain-like<br /> &nbsp; b.18.1: Galactose-binding domain-like<br /> &nbsp; b.18.1.30: CBM11</p> <p>For each entry, the ASTRAL database provides a reference to the PDB&nbsp;entry with chain and residue identifiers plus a sequence. The&nbsp;importlet in /code/import_structures reads this information, downloads&nbsp;the corresponding PDB entry in mmCIF format, extracts the domain,&nbsp;checks that its sequence matches the one given by ASTRAL, and stores&nbsp;the domain in MOSAIC format.</p> <p>For a small number of ASTRAL entries, this process failed for various&nbsp;reasons: mismatch between the ASTRAL reference and the PDB data,&nbsp;mismatch in the sequences, a mistake in the PDB mmCIF file, or&nbsp;unjustified hypotheses in the conversion script. The number of&nbsp;failures was deemed sufficiently small (28 failures out of&nbsp;13042 entries) for not attempting a&nbsp;time-consuming in-detail analysis of each failure. The list&nbsp;of missing entries (generated automatically during the import process)&nbsp;can be found in this ActivePaper under /documentation/missing-entries.</p>
