  1. ftp xray.bmc.uu.se
    login as anonymous with your email as password
    cd into pub/gerard
    Get the rave suite of programs for eg since I have a mac I get rave_osx.tar.gz from the osx directory
    Then chmod +x the executables you just downloaded
  2. To convert map from cns to ccp4 format you would run the following
    osx_mapman
  3. AT the MAPMAN> prompt  read in the map into a variable called slot1
    re slot1 mapfilename_cns.map
    When mapman asks you which format - say X-PLOR for the cns format which is the input map , that you are storing in slot1
    X-PLOR
  4. Then write out the map
    wr slot1
    When mapman asks for filename , enter what you want the file to be called
    mapfilename_cns_convertedccp4.map
    Then when it asks for format enter CCP4
    CCP4
  5. If all goes well you will have the converted map. Also some maps tend to be big and may fail with a MAPSIZE error. Then you need to set the environment variable as follows
    setenv MAPSIZE 1111111 ( for cshrc  e.g)
    or
    export MAPSIZE=11111111 ( for bashrc eg)
    Set  these in the unix/linux/osx shell you use before you execute the mapman executable and then repeat the steps
