PCR

  • /make-pcr-oligos.py - given target sequence, generate oligos that can be used for PCR assembly of that sequence
  • /random-sequence.py - generate random DNA sequence of specified length
  • /primer.py - given upstream and downstream sense sequence of region to amplify, print out correct primers

Nanostructures

  • /toehold.py - given input sequence generate N-mers orthogonal (to seq and its complement) to be used as toeholds
  • /hexgui.py - Tk GUI for honeycomb lattice program

DNA sequence manipulation

  • reverse complement & remove whitespace 
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
