In the first part, FREQ calculates the frequency of the tuple introduced and makes a graphic representation of this in the DNA Chain.
We can see an image in x5 resolution, and we can also see a list of positions of the tuple.
For example, if we put this Fasta file:
homo.fna
>AB000263 |acc=AB000263|descr=Homo sapiens mRNA for prepro cortistatin like peptide, complete cds.|len=368 |
And search for this tuple: AT.
We will obtain this result:
If we want to see the x5 resolution image, we have to make click in the link of down:
And if we want to know all the positions where this tuple is, we also can make click in the other link:
