I have 3000+ RNA sequences in which I have mapped sites of putative endonuclease cleavage. I hypothesize that cleavage site nucleotides are located within regions relatively free of secondary structure. I obtained the RNA sequence 50 bases upstream and 50 downstream for each candidate cleavage site nucleotide, giving me input sequences 101 nt long. I then used the standalone version of RNAfold to predict the RNA foldings of each sequence. This program can give me the positional entropy for each position, as shown by mountain plot in the web version. I would like to extract the entropy positional values for all the calculated foldings so that I can plot the positional entropy averaged over all sequences. However, I cannot find the entropy positional values in the outputted .ps files in the standalone version. How can I get this information?
