  • conver bam to fastq

    hi, I try to convert the bam produced by pacbio sequel platform to fastq file. The output file showed the detailed sequence, but the quality values were all "!". both "bamToFastq" and "samtools bam2fq" were used.

      Sequel data does not have a per base QV value for raw reads. If you calculate CCS first then the quality values will be meaningfully populated.

          Strategies for Sequencing Challenging Samples
          by seqadmin


          Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
