I'm taking an online bioinformatics class and I am stuck on a problem. The resources I have found don't help that much. Here is the problem:
"Assemble the error-free reads from a circular genome on the dataset below. You do not need to consider the reverse complement of the reads.
Dataset: CGTTCT CTAG GACGT TAGAC
As the reads do not have the same length, convert the reads to 4-mers using the approach proposed by Idury and Waterman."
I believe this means I need to convert this into sets of 4 characters each. Do I simply break them up by taking the first 4 characters and last 4 characters like this?
CGTTCT: CGTT --> TTCT
CTAG: CTAG --> CTAG
GACGT: GACG --> ACGT
TAGAC: TAGA --> AGAC
And end up with a new dataset of: "CGTT TTCT CTAG GACG ACGT TAGA AGAC"?
Or is there more to it than that? Thanks for any help.
