Here is the main step in the DADA2 pipeline, which uses the 'dada()' function and dereplicate data.
1 | do_sample_infer_step(filt_Fs, err_f, filt_Rs, err_r, name_samples)
|
filt_Fs |
filtered forward sequences |
err_f |
error rates from filtered forward sequences |
filt_Rs |
filtered forward sequences |
err_r |
error rates from filtered reverse sequences |
name_samples |
vector of sample names |
For DADA2 to work efficiently, samples sequences are dereplicated into "unique sequences" with corresponding counts of these sequences.
This step reduces compute time by eliminating redundant comparisons.
**Note**: DADA retains quality information associated with each unique sequence. It averages the sequences for each unique sequence. These quality scores are used in the error model.
It is intended to take the output filtered results from 'filterAndTrim()' into this function.
Returns list of
mergers
merged paired reads
dadaFs
inferred sequence variants for forward sequences
dadaRs
inferred sequence variants for reverse sequences
