%GC in sliding window calculation

Sliding window program to compute the %GC in sequence of nucleotides.

Input

• Mode (file or sequence input)
• DNA sequence
• The window size (assume the window increment is 1)

py %gc_sliding_window.py 1 NCNACT 3

output

• Nucleotide number
• %GC for each window

Window 1: NCN
Nucleotide number: 3
There are 0.0 Gs, 1.0 Cs, 0.0 As and 0.0 Ts, in the DNA strand.
GC content is: 33.333333333333336%
======================
Window 2: CNA
Nucleotide number: 3
There are 0.0 Gs, 1.0 Cs, 1.0 As and 0.0 Ts, in the DNA strand.
GC content is: 33.333333333333336%
======================
Window 3: NAC
Nucleotide number: 3
There are 0.0 Gs, 1.0 Cs, 1.0 As and 0.0 Ts, in the DNA strand.
GC content is: 33.333333333333336%
======================
Window 4: ACT
Nucleotide number: 3
There are 0.0 Gs, 1.0 Cs, 1.0 As and 1.0 Ts, in the DNA strand.
GC content is: 33.333333333333336%
