This image is not really true. Most of the time we do not have the reference genome of the bacteria, so we look for the closest relatives. And we do not really care where it maps on the reference.
What we are more interesting is to identify a taxonomic assignation for the reads

I would not put the schedule here (but in the handbook), because we could use the slides not only for a 2-days workshop and also we are not sure about the timing

I am not sure to understand why krona for Image data. Maybe cell imaging would be a better example

### Discuss: What kind of data will we encounter?

---

### Types of Data We Will Have

- **Raw Signal** (e.g., current/time-data of MinION)
- **Sequence Data** (e.g., FASTQ data)
- **Interpreted Data** (i.e., results of Kraken)

Maybe better here to show the output table of Kraken, like

d__Eukaryota 2053
d__Eukaryota,k__Fungi 2053
d__Eukaryota|k__Fungi|p__Ascomycota 2049
d__Eukaryota|k__Fungi|p__Ascomycota|c__Saccharomycetes 2039
d__Eukaryota|k__Fungi|p__Ascomycota|c__Saccharomycetes|o__Saccharomycetales 2039
d__Eukaryota|k__Fungi|p__Ascomycota|c__Saccharomycetes|o__Saccharomycetales|f__Saccharomycetaceae 2026
d__Eukaryota|k__Fungi|p__Ascomycota|c__Saccharomycetes|o__Saccharomycetales|f__Saccharomycetaceae|g__Saccharomyces 1916
d__Eukaryota|k__Fungi|p__Ascomycota|c__Saccharomycetes|o__Saccharomycetales|f__Saccharomycetaceae|g__Saccharomyces|s__Saccharomyces cerevisiae 1807

And after a slide with the Krona chart.

What do you think?

As the content here is mostly text, not slides, we could maybe move it to the Sequencing protocol as a comment for the teachers

### Technical Remarks


- Double strands are required for nanopore-sequencing, because single strands would stop at the point where you have your adapter (ds position).
- The nanopore itself is strong enough to open up the ds. A helicase is not necessary.
- The MinION has 4 pores for 512 channels (in total 2048 pores).
- During the sequencing the MinION uses only one pore per channel. Every hour the lane will be checked and perhaps the MinION swaps to a different pore.
- The quality of the reads decreases at the end of a read like in Illumina Sequencing.
- Average length 2-10 kb reads. Error Rate 15-40%.
- Change between template and complement strand is recognized by a specific signal of a site located in the hairpin adapter.
- [Literature](https://www.researchgate.net/publication/317848322_Nanopore_sequencing_data_analysis_state_of_the_art_applications_and_challenges)

---

### Base Calling


- Decoding the raw current signal into a base.
- Long stretches of the same base might induce a higher error (e.g., Poly-A-Tail problem).

---

### RNA Sequencing


- RNA sequencing is possible but so far you need to do a RNA PCR into ds strands (see technical remarks).
- Also possible is the standard way of a reverse trascription into cDNA and then a cDNA PCR.

---

### Max Scan


- It is the name for Nanopore's Current Checking.
- It will automatically determine which pores has the best electric field.
- Then the MinION will pick those pores for seqeuncing.
- This feature is important, since the quality can change over time for the base calling of the each pore.
