[chimerax-users] Placement of markers after translation

[Helge Paternoga]

Dear ChimeraX team,

I have a question regarding the placement of markers.

I am currently trying to extract densities from cryo-EM maps for figure 
preparation. Therefore, I am using markers to colour any density that is 
not part of what I want to extract and then split the map accordingly.

I noticed that when I translate a markerset, e. g. by using "view 
position" with "sameAsModels", new markers are not placed at the cursor 
position, but instead are transformed according to the translation of 
the whole markerset. Therefore, to move markers, I have to use the "move 
marker" command on each marker separately. I would like to know if this 
behaviour is intented and if it can be switched somehow to place markers 
at the cursorposition even after translation of the markerset.

Ultimately, I would like to re-use defined markersets for extracting (or 
"cleaning") the same invariant components of my maps. But the current 
behaviour makes it nearly impossible to add new markers for touch-ups 
after opening and aligning a markerset.

Best,

Helge
