<p class="MsoNormal" style="margin-bottom:12.0pt">This should work I think. To get the model centered on the box, you can first center on the new map, then use the "cofr model" argument of "move" to move the molmap model to the center of rotation before resampling
on the new grid.<br>

> There is no way to directly specify a cube in the "molmap" command. It does have an "onGrid" option to generate the map on the grid of another map. So one possibility might be to make a blank map with "volume new" with the desired "size" and "gridSpacing"
values and then use that zero-valued map with the "onGrid" option of "molmap." The tricky part might be making the zero-valued map go in the right place, but maybe it would work to just make it first and then move the structure inside of it rougtly at the
center after showing its (the map's) outline box. <br>
