[phenixbb] Format problem of restraint file

Hi everyone, I generated the basepairing restraint file by command phenix.secondary_structure_restraints MR.1.pdb > ss.eff . Then I opened the ss.eff file with gedit and edit the basepairing information. However, after I finished editing and saved the file, the refine program can not read the file. The error is "This application does not support the file type for ss.eff (format:txt)". I have attached a copy of the eff file. Do I have a way to solve the problem? Thanks for your help! Sincerely, Xiang
