<div dir="ltr"><div>Are there any methods in BioJava's API to create electron density maps from structure factors? <br><br>The RCSB Protein Data Bank has switched from providing .mtz format to using a .cif format for the structure factors. BioJava already has mmCIF parsing for _loop records that relate to the protein structure and could probably easily support the new format for providing structure factors.<br><br>Using structure factors /w generated phases from coordinates and to create density maps would be a harder task. Is there any interest in this kind of functionality in BioJava? <font size="2"><span style="font-family:arial,helvetica,sans-serif">I saw a recent discussion related #224 (</span></font><font size="2"><span style="font-family:arial,helvetica,sans-serif"><span class=""> Extend biojava-structure to better support energy minimization ) that looked like a promising area that could benefit from having real electron density or methods for calculated structure factors.</span></span></font><font size="2"><span style="font-family:arial,helvetica,sans-serif"></span></font><br></div><br><div><div><div>-- <br><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr">Matt Larson, PhD<br>Madison, WI 53705 U.S.A.</div></div></div></div>
