Sort multi-isoform gene models by feature type (default: False) -v, –version. features # if an embedded ##FASTA directive is found, parse the sequences into gff. We suggest improvements for each of the GFF3 fields, as well as the special cases of modeling functional annotations, and standard protein-coding genes. This documentation focuses on GFF3 formatting conventions, but GTF conventions to use for submission are similar. The proposed GFF3 format addresses the most common extensions to GFF, while preserving backward compatibility with previous formats. py < mydata. to their respective locus, resulting in the desired number of isoforms for each locus. 3 is "Annotations in GFF format", which describes how to specify the proper tag indicating parent-child relationships. 在各个行业都是有行业标准的，这样才能统一规范而方便后面的分析，在生物信息学领域中主要是各种大量序列数据、注释数据等，这些都是有特定的格式去表示，下面列举几种常见的格式。 Unofficial attributes.
