Hi,

I generated a difference map using MatchMaps (https://github.com/rs-station/matchmaps). However, when I load the map in ChimeraX, the density appears split into two distinct regions.

Interestingly, this does not occur when the same map is opened in Coot, where it displays as expected.

I have attached a screenshot for reference.
Any ideas on how to “unsplit” the map or what might be causing this behavior?

Thanks in advance.
