**RNAinverse**

The program searches for sequences folding into a predefined structure, thereby inverting the folding algorithm. For each search the best sequence found and its Hamming distance to the start sequence are printed. If the the search was unsuccessful, a structure distance to the target is appended.


-----

**Input format**

Input is similar to a Fasta file. First line should be the structure in dot-bracket notation, second line the starting sequence. Lines with '>' in the beginning are treated as comments. Characters in the start sequence other than "AUGC" will be treated as wild cards and replaced by a random character. Any lower case characters in the start sequence will be kept fixed during the search. If necessary, the sequence will be elongated to the length of the structure. Thus a string of "N"s as well as a blank line specify a random start sequence.

------

**Outputs**

- text output of each sequence with its Hamming distance and/or the energy if the partition function is selected
