I tried to get the centroid from

obb\_centroid = np.array(stats[segmentId,“LabelmapSegmentStatisticsPlugin.centroid\_ras”])

but it gives KeyError.

Can someone help me how to do that properly ?

thanks

You need to enable the `LabelmapSegmentStatisticsPlugin` plugin and the computation of the `centroid_ras` value.
