  "abstract": "<p><strong>Background:</strong>&nbsp;Atrial anisotropy affects electrical propagation patterns, anchor locations of atrial reentrant drivers, and atrial mechanics. However, patient-specific atrial fibre fields and anisotropy measurements are not currently available, and consequently assigning fibre fields to atrial models is challenging. We aimed to construct an atrial fibre atlas from a high-resolution DTMRI dataset that optimally reproduces electrophysiology simulation predictions corresponding to patient-specific fibre fields, and to develop a methodology for automatically assigning fibres to patient-specific anatomies.</p>\n\n<p>&nbsp;</p>\n\n<p><strong>Dataset Description:</strong>&nbsp;We include&nbsp;endocardial and epicardial left and right atrial surfaces for each of the 7 anatomies included in our study (Constructing a Human Atrial Fibre Atlas, ABME, 2020),&nbsp;together with their fibre fields. We also include&nbsp;the average fibre field for each of the atrial surfaces displayed on anatomy number 6 (named *_A).&nbsp;</p>\n\n<p>For each of the surfaces, we also include universal atrial coordinate fields alpha and beta, which are a lateral-septal coordinate and posterior-anterior coordinate for the LA (IVC-SVC coordinate for the RA). More details on the coordinate construction are given in our manuscript and&nbsp;<a href=\"https://www.ncbi.nlm.nih.gov/pubmed/31026761\">https://www.ncbi.nlm.nih.gov/pubmed/31026761</a>. These coordinates can be used for registering datasets.&nbsp;</p>\n\n<p>These meshes are in vtk format, consisting of the nodes, triangular elements, the atrial coordinate fields defined on the nodes, and the fibre field defined on the elements.&nbsp;</p>\n\n<p>We have also included mesh files for the Cardiac Arrhythmia Research Package simulator. These are a list of nodal coordinates (.pts file), a list of triangular elements (.elem file), and a fibre file (.lon). More details on this file format and the carpentry simulator are available at:&nbsp;<a href=\"https://carpentry.medunigraz.at/carputils/index.html\">https://carpentry.medunigraz.at/carputils/index.html</a>.&nbsp;</p>",
