<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Hi!<div><br></div><div>I have been using a program called Curves for analyzing nucleic acid crystal structures for quite a while and I have always used Chimera to visualize the output pdb. One file shows the backbone splines and the vectors defining the nucleic acid groove widths (r+bdna_b.pdb) and the other file shows the nucleic acid helical axis (r+bdna_X.pdb). Chimera has always been able to read both of these files until the recent production release where it is no longer able to read the r+bdna_b.pdb file. I have attached the two files and the actual DNA pdb file. Can you please help me fix the problem with reading the r+bdna_b.pdb file in the new production release?</div><div><br></div><div>Thanks,</div><div>Dave<br><div> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>--------------------------------------------------------<br>David Chenoweth<br>NIH Postdoctoral Fellow<br>Swager Research Group<br>Massachusetts Institute of Technology<br>Chemistry Department, 18-053<br>77 Massachusetts Avenue<br>Cambridge, MA 02139<br><br>Email: <a href="mailto:dcheno@mit.edu">dcheno@mit.edu</a><br>Lab Phone: 617-258-6537<br>--------------------------------------------------------</div><div><br></div></div></span><br class="Apple-interchange-newline"> </div><div></div></div></body></html>
