It does not matter that the voxel size is different. The matrix being copied is one that transforms the model physical coordinate system (usually in Angstroms) to the world coordinate system (also in Angstroms). The voxel size is how grid indices are converted to physical units (Angstroms) and is not a factor for aligning the two maps with matrixcopy.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>Tom</div><div class=""><br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Aug 29, 2019, at 1:35 PM, Oleksiy Kovtun <<a href="mailto:okovtun@mrc-lmb.cam.ac.uk" class="">okovtun@mrc-lmb.cam.ac.uk</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><meta http-equiv="Content-Type" content="text/html; charset=us-ascii" class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;" class="">Dear community, <div class="">I need your advice on the following problem.</div><div class="">I align map #1 to the reference volume using fit command, and then need to confer this transformation to map #2.</div><div class="">This could be done by using matrixcopy command.
