How to filter low quality Kmers in raw fastq file

[yhg926]

Hi, Dr Zhao:
Does bindash have option to filter out low coverage or low quality Kmers in fastq file?
I believe these Kmers will bias distance estimation
Many thanks

Sorry for the extremely late reply. BinDash has no option to filter out low coverage or low quality k-mers in fastq files.
I believe that, in theory, these low-quality k-mers would add no bias to the distance estimation, but it would add variance to the bias estimation, causing more random noise.
Please feel free to open a feature request for discarding k-mer with any low base quality if you would like.
