I have a text file which shows a column of position of TF and strand(+ or -) and another column showing total sequence length. I want to create a program which can take an input of a starting integer and add the position of the TF and depending on whether the strand is positive or negative, we can either subtract or add the first added position of the TF. It should show one column showing TFBS positions which has the first position of the TFBS added with the position and the final position coming from either subtracted or added from the type of strand given. Thank you. I am adding the few of the lines of the file for a better understanding:
Position (Strand) Factor Name Sequence Total Sequence Length 201 (-) HNF-4 tgttgaaCTTTAagccaac 19 700 (+) Pax-6 gaagtTCACGgttcacatatt 21

i am grouping my way at these maths , which I could not do with out you. You cover every question step by step and of top quality , inch by inch you guide me along the path, maybe a little expensive for me (71 years old who had a stroke) but top quality.
