7977	DICOM: SEG models not aligned with CT 4	Elaine Meng	Zach Pearson	"In the RIDER lung example for one patient
(data /wynton/group/ferrin/usr.local/projects/chimerax/www/data/dicom/98820 RIDER-1129164940.tar.bz2 )
...there are two CTs (CT4 and CT8) and eight SEG models. I know that series are not necessarily aligned but in earlier versions of ChimeraX, when I opened this folder the SEG models were all aligned with CT 4, i.e. they were segmentations based on that scan.  So I suspect that the SEG models are now missing the proper transformation.  CT 8 is offset from CT 4, which I expected, because this was also the case in earlier versions of ChimeraX.

In UCSF ChimeraX version: 1.5rc202211080803 (2022-11-08) when I show all the datasets as full volumes with the SEG ones in surface style, they are far offset from both CTs.  Screenshot attached."	defect	closed	major	1.6	DICOM		fixed						all	ChimeraX
