Hi Jean-François,<br>
<br>
When you use the Segment Map tool (also known as Segger) and mask
the map to a selected region (for example, using menu entry Regions
/ Mask Map with Selected or File / Save Selected Regions to .mrc
File) the new masked map outside the region is set to zero. The
segmentation regions only extend to the displayed map contour when
used when you created the segmentation. So the rough surface of the
masked map is because the map drops to zero abruptly. The only
reasonable fix is to use a lower contour level when doing the
initial segmentation, a level lower than you will use later when you
display masked regions. There is no ability to roll off the mask
gradually at the boundary.<br>

<br>
I am using the segmentation tool on a ~15A cryoEM map. I have
noticed that the surface of the mrc maps saved from selected
areas look pixelated. Any suggestions how to improve the
quality of the segmented maps ?<br>
<br>
Best wishes<br>
