The basecalling and alignment can be performed separately? #7

Hello, According to the Example, the basecallings and alignments were completed together. For the part of Methylation Calling from Guppy basecalled FAST5 files, the Guppy basecalled FAST5 files and BAM files containing alignments are required. Can I produce these two files separately as following steps: First, basecalled fast5 files and FQ files containing read sequences are generated using Guppy. Second, BAM files are generated by aligning FQ files to reference genome using minimap2. Third, the basecalled fast5 files and BAM files were fed to DeepMod2.

    Thanks!

Hi,

Yes you can definitely separate basecalling and alignment steps. The example only does it in a combined way for the sake of brevity, but even in that case Guppy uses mnimap2 for alignment.

Best, Umair
