Hi Warren, Now I am more confused. I used align command to measure the overall RMSD between homologous structures. Apparently align is not appropriate if not sufficient sequence similarity is present. I later came across CEalign plugin, which does structure-based superimposition. This comm

Hey Thomas, if you want to use align anyway, make sure to use the quite=0 option. The "quiet" option (if present) is set to zero by default for parsed PyMOL commands, but is not set for Python API calls. align is nearly equal to cmd.align(quiet=0) Thus, if you want to get rmsd output, include qu

Tom, The complication with cmd.align() is that it is doing a whole lot more than a simple alignment. The first number is in fact the RMS, but it covers only the subset of the input atoms remaining after refinement is completed. The count of aligned atoms is the second field. If you're looking
