Errors and letters
As we are all human we all make mistakes. You may find after your paper has been published that it contains an error. If this happens you need to contact the editorial team immediately, the paper cannot be changed (it will already have been deposited with DOI) but an addendum to the paper can be published in the journal as soon as possible. If the error is a major one eg, there was a problem with your original study that now invalidates your findings the paper may be retracted, but this is very rare.
