  each time I use an afni interface I have not been using for a long time I spend 4 hours fixing some bugs that goes down to base interface specs......
  fix tcorrmap for use of source_name, depends on recent fix cline_bug branch
  fix the TCorrMap histogram options
  3drefit does not accept -prefix option, since it operates on its own file now it will work if you give the same out_file name as in_file name however if you give no out filename it might not work if your infile is a .nii or .nii.gz since afni will make briks
Fixed P2PDistance

Interface failed because tvtk is loaded with the default value
of ETSConfig.toolkit. Now it is initialized, so now the enthough.traitsui
does not look for $DISPLAY.
