You fit it to the starting position and record that position with the command "view name pos1" command, then fit it to the final position and save that position with another "view name pos2". Then you could use the command "fly 100 pos1 pos2" to move have the map fly between the two positions over 100 frames. This does not change the shape of the mobile density it just moves it. If you wanted to change its shape while it flies to the new location you could use the "volume morph" command to change its shape while the fly command moves it.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>Tom</div><div class=""><br class=""></div><div class=""><br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Aug 18, 2022, at 6:46 PM, HONG ZHAN via ChimeraX-users <<a href="mailto:chimerax-users@cgl.ucsf.edu" class="">chimerax-users@cgl.ucsf.edu</a>> wrote:</div><br class="Apple-interchange-newline"><div class="">

Thank you Elaine for the quick response! I did use the volume resample, but I misunderstood the onGrid pointer… I made it!

<div class="">The volume morph dissolves one part of the complex and appears the other, but I want to have a "movement movie", like using morph for atomic models, one part of the complex flies out and fit into the other part, is there any functions I missed? </div>

Hi Hong,
<div class="">As mentioned in the volume morph" help, </div>
<div class=""><<a href="https://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#morph" class="">https://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#morph</a>></div>
<div class=""><br class="">
</div>
<div class="">"the input maps should have the same grids: dimensions, spacing, and numbers of points. Note <b class="">volume resample</b> can be used to make a copy of one map that has the same grid as another."</div>
<div class=""><br class="">
</div>
<div class="">Here is the "volume resample" help, with explanation that you can lose some resolution from resampling:</div>
<div class=""><<a href="https://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#resample" class="">https://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#resample</a>></div>
<div class=""><br class="">
</div>
<div class="">There is also a "volume add" if you are just trying to put different parts together, rather than morphing:</div>
<div class=""><<a href="https://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#add" class="">https://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#add</a>></div>

<div class="">I hope this helps,</div>

Dear user group, <br class="">
<br class="">
I am trying to do volume morph to transform different parts of a complex into another part of the same complex. Because I did drag and fit each segmented parts, the map positions are no longer the same and I have this error: Map positions are not the same. <br class="">
<br class="">
Is there a way to do the map morph to transform different map parts in the complex?<br class="">
<br class="">
Many thanks!<br class="">
Hong<br class="">
