DNA sequence manipulation

  • reverse complement & remove whitespace

<syntaxhighlight lang="python"> complement = string.maketrans('ACGTacgt','TGCAtgca') def comp(s):

 return s.translate(complement)[::-1]

def nowhite(s):

 return .join([c for c in s if c in string.letters])


  • replace mac return character ('\r') with unix return ('\n')
cat foo | tr '\r' '\n' > bar
mv bar foo
