Now, I want to save 1 pdb file containing target + one of poses of ligand for example, number 3.

For this aim, what to do?

I did following steps, but I did not succeed:

file ---> save pdb ... 

In save models section, I selected both of target.pdb (#0) and (#1.3)

In file name section, I wrote complex.pdb and then save.

I encountered with error (see the below link):

I tested other names such as $target.pdb and $1.3.pdb.

Unfortunately, I encountered with the same error.

Best regards,
