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
BioRead objects to
store and manage sequence read data containing information on headers,
qualities, and alignments.
