My name is Adrian. I am a graduate student at Bar Ilan University in Israel.  I have 2 pdb files, each containing rRNA sequences and I would like to combine the 2 to make 1 pdb file displaying all of the rRNA subunits.  I download the Chimera program.  Is it possible to do this on your program and if so, can you please tell me how?

Thank you so much,

Adrian
