Looks like you are trying to put non-RNA letters into an RNA object:

   > RNAStringSet("e", use.names=TRUE)
   Error in .Call2("new_XString_from_CHARACTER", classname, x, 
start(solved_SEW),  :
     key 101 not in lookup table

In BioC devel, the error message also displays the letter associated
with the code:

   > RNAStringSet("accgaggaudnugeacc", use.names=TRUE)
   Error in .Call2("new_XString_from_CHARACTER", classname, x, 
start(solved_SEW),  :
     key 101 (char 'e') not in lookup table
