[Chimera-users] Save a transformed density map

Hi Keren,

   You can save the Chimera session to preserve the orientation of one 
map fit into another.

   If you want to write a new map so that when it is loaded in Chimera 
and other software it will be at the correct place in the map it was fit 
into that is harder.  The problem is that none of the map file formats 
provide for a positioning transformation in the header.  So it would be 
necessary to resample the map that you fit on the grid of the map you 
fit into.  Resampling interpolates data values and can degrade map 
quality.  Do you want to do that?
