Using the GUI I can turn the molecule and save the pdb after unclicking the "Use untransformed coordinates" box. However, when I run a script using the write command I don't know how to invoke this option. The docs on the "relative" option suggest that the default is to write transformed coordinates.<br class=""><br class="">I've tried the following:<br class="">for i in xrange(0,90,10):<br class=""> rc("rock " + "y " + str(i) + " 1")<br class=""> fn = basefn + str(i) + '.pdb'<br class=""> rc("write format pdb 0 " + fn)<br class="">and the files end up identical although the rotation around y does appear on the screen. I had the problem in version 1.10.2 and it remains after upgrading to 1.11.<br class=""><br class="">thanks for your help,<br class="">Michael</div></body></html>
