Question

[ธาดา]

Hi, I am a beginner in nanopore. So I study about the guppy basecaller and try to use it. In normally from each peak in raw signal that represent current for each 5-mer. I wonder why in this picture that show the only 1 base for each peak instead show AACAT, CCGGT?

Probably because they wanted to keep the representation simple and are just showing the consensus calls on one strand.
