[phenixbb] Issue with phenix.superpose_maps

Hi all,
I'm trying to use phenix.superpose_maps through the GUI to get
superposed maps covering the same region of NCS-related chains A and B
for a figure. I have used PDB Tools to split the model into two files
with only chain A or chain B. However, when I run superpose_maps
specifying the two individual chains for the input PDB files but the
same mtz file for the map coefficients I only get one output map (I
think it overwrites the output file...). Selected input from the
generated .eff file is as follows:
input_files {
map_1 = "/home/stepheng/blah/Native_refine_6_map_coeffs.mtz"
labels_1 = 2FOFCWT,PH2FOFCWT
map_2 = "/home/stepheng/blah/Native_refine_6_map_coeffs.mtz"
labels_2 = 2FOFCWT,PH2FOFCWT
pdb_1 = "/home/stepheng/blah/Native_refine_6_chainA.pdb"
d_min_1 = None
pdb_2 = "/home/stepheng/blah/Native_refine_6_chainB.pdb"
d_min_2 = None
output_dir = "/home/stepheng/blah"
}
And the end of the output is as follows:
saving CCP4 map to Native_refine_6_map_coeffs_superposed.ccp4
Wrote Native_refine_6_chainA_superposed.pdb
Wrote Native_refine_6_map_coeffs_superposed.ccp4
saving CCP4 map to Native_refine_6_map_coeffs_superposed.ccp4
Wrote Native_refine_6_chainB_superposed.pdb
Wrote Native_refine_6_map_coeffs_superposed.ccp4
A bug?
Stephen
P.S. Incidentally, is there any reason you write both maps in a P1
box rather than putting map 2 on top of map 1 in the position of the
first (reference) model? The latter would be more convenient as you
can then re-use your carefully chosen pymol viewing matrices for all
figures...
