Hi Trevor, I don't know whether this will meet your needs or not, but you could try using Unit Cell (under Tools... Higher-Order Structure): http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/unitcell/ unitcell.html It will generate additional copies using MTRIX, SMTRY and/or CRYST1 matrices. I am hoping the refmac map will go along with one of those copies, but a disadvantage of the approach is that you will have the other copies too (could tax the system depending on number/size). The extras could be removed after you get the copy you want, however. I hope this helps, Elaine ----- Elaine C.

Hi,
It often turns out that the atomic model you create in O needs to be transformed by a crystallographic symmetry operation in order to fit into the map created by refmac. In O this is no problem because the map automatically covers the bit of model you put in the center of your screen. However this does not seem to happen in Chimera. Is there an easy way to make the map cover the model (i.e. without working out what the transformation is and then creating a transformed pdb file)?
Many thanks
Trevor
