A tool to visualize fastq alignment with quality-score
Do you need to eyeball through fastq alignment file, with special features to highlight the quality score of each bases? Introducing fastqviz, a Streamlit app which can do just that. I made it quite some time ago to visualize some amplicon data for my own project. You can upload your fastq file. The fastqviz viewer…
