This function relies on the locus_tag field present on every child of a gene feature. The file needs to be in the same directory as the program, if not you need to specify a path. the protein_id (see below). Can anyone offer some suggestions as to why the entire genbank file is not parsed, how I could modify my code to remove this issue, or point me to another possible solution?

A straightforward application to convert NCBI GenBank format files to a swath of other formats. Here I focus on parsing Genbank files; SeqIO can be used to parse a bunch of different formats, but the structure of the parsed data will vary. """Get genome records from a biopython features object into a dataframe Using this, we could build parsers that can be used on vast text data or any unstructured data. Python packages; taxoniq-accession-lengths; taxoniq-accession-lengths v2021.3.23. Then, we set a back to 0 if this line matches /translation. Use MathJax to format equations.
