in thread replace fist and last occurrences of N

Ok, what about newlines? Are there newlines in your datafiles? Or are they just one long string consisting of character class [a-zA-Z]?

    yes, there are new lines
    the files looks exactly like in your example (DATA)
    thses are dna files of whole genomes and they are quite large....
