[phenixbb] Stretched Maps

[Pavel Afonine]

  Hi Joel,

it used to be the known issue for some rare cases until I fixed it a few 
months ago. So:

1) could you please try the latest PHENIX from nightly builds and see if 
you still have this problem:

2) if you still have this problem even using the latest PHENIX, then 
please send me the data and model (and, optionally the command you used 
that lead to these maps) and I will investigate.

Pavel.
