Hey Elaine, I've managed the occupancy error. Thanks for that. I also managed to upload the two pdb files and now I'mwaiting for the job to be done. Thank you and have a nice day!

I hope this helps, Elaine ---------- Elaine C.

Hey, Is it possible to change occupancy field to 1.0 in Chimera?

I need a pdb file of my protein for docking and the file needs to have an occupancy field 1.0.

Thanks for the help
