Data Import

Import Next-Generation Sequencing (NGS) data and feature annotations from SAM, BAM, FASTA, FASTQ, GTF, and GFF files

Import NGS data stored in different file formats such as FASTA, FASTQ, SAM, and BAM files. Read feature annotations from GTF and GFF files. Use various objects to access and manage NGS data. For instance, the BioIndexedFile object lets you efficiently access text files with nonuniform-size entries, such as sequences and annotations. Use the object to access individual entries or a subset of entries when the source file is too big to fit in memory. Use the BioMap and BioRead objects to store and manage sequence read data containing information on headers, qualities, and alignments.
