[chimerax-users] a question about CMM files

[Pranav Shah]

Hi Team,
How are XYZ coords represented in ChimeraX?
I have a volume of 794x794x272 sampled @15Å/px. When I place markers
in the volume and save the resultant marker file, the coords for the
points are as follows-

<marker_set name="markers">
<marker id="1" x="6950.3" y="6659.4" z="2010" r="1" g="1" b="0" radius="15"/>
<marker id="2" x="6977.7" y="6381.5" z="2010" r="1" g="1" b="0" radius="15"/>
<marker id="3" x="9747.8" y="3926.7" z="2010" r="1" g="1" b="0" radius="15"/>
</marker_set>

Such large numbers seem to imply that the dimensions are measured in
physical units (Å in this case). Is this correct?

Best,
Pranav
