<meta http-equiv="content-type" content="text/html; charset=UTF-8" class=""><p class="">Hi Tom,</p><p class="">To the best of my understanding, ChimeraX displays images and
associated segmentations in physical space not image space.
However, segmentations are performed in image space. EMDB-SFF
uses the first transform in the transforms_list field (with
id=0) as the image-to-physical transform.

different values for transform 0 and they render the same.</p><p class="">Could you please implement this feature in ChimeraX?</p><p class="">Kind regards,<br class="">
