cburger has asked for the
wisdom of the Perl Monks concerning the following question:
I'm trying to write a script which replaces one letter with another for nucleotide bases. e.g. A with T. when I write:
for example I want to convert this string:
I wrote something like:
the replacement is not correct and I get for the print out:
what is happening? why is sub always T and not changing? I dont see the problem with the lines.. thanks for the help!
thanks everyone! I could figure out the problem now. Indeed the eq sign mix up was the problem, and I wasnt aware of the tr// possibility. Painful learning from sloppiness...Thanks again for the help perlmonks!
