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!

Hi Darjan,
If you have occupancies that are < 1.0 there may be atoms with alternate locations (more than one position included in the PDB file), and you may wish to remove all but one set of locations, for example, using the option in Dock Prep.

You can change occupancies with the "setattr" command, for example:

setattr a occupancy 1.0


Then you can save a new PDB file containing all occupancy values = 1.0.
I hope this helps,
