How to choose reads type to the downstream process? #30

Hi, I am processing the nanopore data for transcriptome analysis, I want to know that I need just use the reads_full_length.fq or I can use all the output reads (reads_full_length.fq + rescued.fq + unclassified.fq) to downstream analysis? If I can use all the reads, the purpose of "cdna_classifier.py" is to trim the primer sequence, is that right?

You only need the reads_full_length.fq.

@bsipos Could you tell me why unclassified.fq can't be used?

bsipos commented 4 years ago

Because they do not have one or both PCR primers identified. Hence they are not guaranteed to be full length in sequencing and their orientation cannot be determined.
