<div>Hi Brandon,
<div class=""><br class="">
</div>
<div class=""> Ok, I added a "mark connected" command to ChimeraX that places a spherical marker on every connected surface piece. If you are hiding dust it only uses the displayed surface pieces. Here's an example</div>
<div class=""><br class="">
</div>
<div class=""><span class="x_Apple-tab-span" style="white-space:pre"></span>open 1a0m from eds</div>
<div class=""><span class="x_Apple-tab-span" style="white-space:pre"></span>mark connected #1 radius 0.2 color gold</div>
<div class=""><br class="">
</div>
<div class="">There is a mouse mode to place a marker on a clicked surface piece under the Markers toolbar, and there is the surface dust command that finds all connected pieces and hides the small ones. I just looked over the Python code for those and combined
them to add this new command. It is a good example of the power of using Python to call existing ChimeraX capabilities. So I made a ChimeraX recipe web page showing how it was done.</div>

<div class="">Hi Brandon,
<div class=""><br class="">
</div>
<div class=""> Yes, the "measure area" command has the includeMasked option default false so the area of the small blobs masked by the surface dust command is not included in the calculation</div>
<div class=""><br class="">
</div>
<div class=""><span class="x_x_Apple-tab-span" style="white-space:pre"></span><a href="https://www.cgl.ucsf.edu/chimerax/docs/user/commands/measure.html#area" class="">https://www.cgl.ucsf.edu/chimerax/docs/user/commands/measure.html#area</a></div>
<div class=""><br class="">
</div>
<div class="">The "measure motion" command shows line segments (hairs, prickles) on a surface showing which direction a surface is moving in a series of surfaces, for instance in a surface depiction of a 3D light microscopy time series. Are you saying that
measure motion shows the line segments even for blobs hidden with "surface dust", and that you want an option to not show the line segments for those hidden blobs? The measure motion command is a rarely used feature and probably no one else ever tried it
with hiding dust</div>
<div class=""><br class="">
</div>
<div class=""><span class="x_x_Apple-tab-span" style="white-space:pre"></span><a href="https://www.cgl.ucsf.edu/chimerax/docs/user/commands/measure.html#motion" class="">https://www.cgl.ucsf.edu/chimerax/docs/user/commands/measure.html#motion</a></div>
<div class=""><br class="">
</div>
<div class="">It is possible to make that improvement but hard to find time to do it.</div>
<div class=""><br class="">
</div>
<div class=""> For tracking the surface as it moves, which points at time t=2 correspond to which points at t=1, that is a complex problem. Maybe the measure motion vectors are a tiny part of a solution. This would produce a large quantity of data matching
many of the surface vertices between every two time points. An critical consideration would be how you are planning to use that information. In general tracking surfaces that split, merge, disappear, ... and analyzing requires a lot of custom written software.</div>
<div class=""><br class="">
</div>
<div class=""> We don't have the funding to supply special purpose surface tracking software so I think it is likely you would need to find other software that can do the job, probably that does not exist, so you would need a programmer to develop it for you.
Maybe what you want it simpler than I think. But you would need to explain it in detail.</div>
