Do you already know the desired rotation and translation for each particle? Or do you want to calculate those fits? What you want is probably possible but I need more details to give specific advice. Chimera is not memory efficient with its molecular models, so if your particles are proteins with several thousand atoms and you want to load 300 of them, you will need a lot of memory (~2 Kbytes / atom).<br><br> Tom<br><br><blockquote cite="mid:D76DD140FBBE5A49BA76B24EE4A4773C0A68396D@SERV-MAILBOX1.igbmc.u-strasbg.fr" type="cite"><div class="WordSection1" style="page: WordSection1; "><div style="margin-top: 0cm; margin-right: 0cm; margin-bottom: 0.0001pt; margin-left: 0cm; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN-US">Dear colleagues,<o:p></o:p></span></div><div style="margin-top: 0cm; margin-right: 0cm; margin-bottom: 0.0001pt; margin-left: 0cm; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN-US"><o:p> </o:p></span></div><div style="margin-top: 0cm; margin-right: 0cm; margin-bottom: 0.0001pt; margin-left: 0cm; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN-US">I would like to fit about 300 particles inside of the map according to it coordinates (X,Y,Z) what I have found before.
