[phenixbb] Creating files with positive and negative map peaks

I would like to obtain a file with a listing of positive and negative difference map peaks, similar in formatting and content to the files that would come out of cns: positive peaks in: _positive.peaks negative peaks in: _negative.peaks We need this for use in DDQ at the jcsg validation server (http://www.jcsg.org/prod/scripts/validation/sv2.cgi). Is there an easy way to create these peak files in phenix.refine? We'd prefer to not re-refine in CNS as we have *many* alternate conformations... Thanks, Jennifer
