Dear concern, this is Asif from BRAC University, Biotechnology program. I hope you're in good health. I need a little help from you. Recently, I have joined two peptide fragments by forming a peptide bond between them using your standalone UCSF Chimera software. The file has been saved as a Chimera session fle. However, I'm not finding any clue on how to convert it into an entire pdb file. I'm not being able to do any other modification to it since a pdb file is required for this purpose. Could you please help me out on this regard? kindly let me know how can I generate a pdb file from that session file format. I wish to hear your reply. Thanks in advance!
