Hello,

I need to translate a DNAstringSet to AAstringSet, where the alternative initiation codons doesn't apply. 

How can I get rid of the attribution?

Tried to set attr(GENETIC_CODE, "alt_init_codons")=NULL, but won't work.

Thank you.

 attr(GENETIC_CODE, "alt_init_codons")=character(0)  works
