[phenixbb] phenix.maps kick maps: seed and error

I have started using phenix.maps to calculate some kicked omit maps and 
had two questions:

1) is there a way to control parameters such as the initial random seed 
or number of kick iterations? Different runs with the same params and 
input files appear to give different map coefficient outputs.

2) after what appears to be a successful run on a pdb containing two rna 
chains and solvent atoms  I (a) removed all non-RNA atoms and (b) moved 
all RNA atoms to corresponding symmetry locations within the ASU. No 
other changes were involved but I now receive the following python stack 

Compute maps.
