WarningThe treatment group [group names] and its isocenter coordinate [coordinate name] are each identified by a different number. The same number should be used where possible. If several treatment groups are assigned to the same isocenter coordinate, unique alphanumeric identifiers should be used. Contact Brainlab support.
