Dear siesta developers and users:

I now need to rearrange the order of the atoms in my system to get the basis 
order altered, but their coordinates are unchanged. After the rearrange of the 
atom order,I want to reuse the previous results for the system to save 
computational time. So I use the SCF.Read.Charge.NetCDF option to read the 
elecron density from Rho.IN.grid.nc and generate the new files I needed for the 
rearrange system with MaxSCFIterations 0 .I expected all the physical 
quantities are the same for the two systems.All the computation is normal but I 
found the generated file was wrong,becasue the quantities are different from 
the previous system. So I guess the grid is relevant with the atom order not 
just correspond to the coordinates of the atoms? (Maybe I misunderstand the 
meaning of grid in the siesta). Is it?

I.e. if the SCF.Read.Charge.NetCDF option is used,the atom order should not be 
changed but the basis set can be altered.


Any discussion is welcome.
