sequence file into a numeric file Posted by sarish (sarish), 23 June 2005 Need some help!!!I have a DNA sequence file and would like to convert each nucleotide (from the file) into some number (say I assign A=0, T=1, G=2, C=3). It sounds quite simple but since I am new to perl I need some assistance. It is basically converting a sequence file into a numeric file and having that in a array format. Each cell having a number relating to a nucleotide. just in case if you have any idea please let me know. Thanks in advance.
