[chimerax-users] Re: issues with writing models as pdb files

Hi everyone, I noticed that sometimes when i write pdb of one model or a selection , it does not open in other programs.( MOE,Pymol). One of the errors i noticed recently was that th pdb file was written as a multi model pdb file ( each of the 70 residues in the protein were separate models) , i cleaned it using notepad++ by removing the model lines and it was opening correctly. i was told that it might be related to using split command. i use split often and it might be the case. can some one please explain how using split can lead to this? and if so what is best way to fix it? should i perhaps run some version of combine command on the model prior to writing it out as pdb file. thanks again, best amith
