[ccp4bb]: Iodine ions, REFMAC5 ?
Dear all,
I am using REFMAC5 including the TLS refinement.
In my pdb file, i specify positions for Iodine ions (I-), for example:
ATOM 5620 I I I 1 -0.525 15.449 40.404 0.70 20.03
and in the same way for 20 additional sites.
I can run REFMAC5 until the end of the refinement without any problems,
but it complains at the beginning and gives the following message:
WARNING : I II 1 : wrong definition of first atom of the tree
WARNING : I II 21 : wrong definition of first atom of the tree
I guess, i should worry about it !?!
What should i change ?
Also, Could someone tell me how to specify the ion and not the normal atom ?
Thank you,
Regards,
Gregory.
