because lower case usually indicates masked regoin. Given a group of DNA seuqneces, we would like to check the positions where it is lower case
is.lower(seq, n)
seq |
a vector, each element is a segment of DNA sequence |
n |
length of each segment |
a matrix of size length(seq) * n, code[i,j] = 1 means the jth position in the ith segment is lower case.
