Question - about the result of kept_barcodes_binned.txt.BCUMIstats.txt

[Dkaaaaa]

Hi, Below is my pm1kept_barcodes_binned.txt.BCUMIstats.txt result. I wanna know how the "nNontagged" and "nUMItag" columns comes.

then i chose the bc "AGATTGACTCACTAGGTGACAC" , and serch it in pm1.filtered.tagged.Aligned.toTranscriptome.out.bam, and i found that UB tag is null

then I got its corresponding reads, and I found that my pattern setted on my yaml is not at the beginning of my reads, below is my reads

below is my yaml text pm1-1.yaml.txt

so the "nNontagged" and "nUMItag" columns result just because of the pattern not at the beginning of my reads?

Hi,

So for this particular 11bp pattern "ATTGCGCAATG" which corresponds to the Smart-seq3 TSO, our pipeline is hardcoded to only take it when it is present in the start of the read! This is why you have 0 UMI reads ("tagged") detected and seeing empty UB tags.

Thanks a lot for your reply. Have a nice day!

What does "hardcoded" mean? How can I solve this problem?
