Then use the BLAST button at the bottom of the page to align your sequences. The extracted text for each block starts with a line that contains spaces at the beginning of the line followed by gene, The extracted text for each block ends with a line that contains /db_xref="GeneID. Seems like the easiest way to deal with this file format is to convert it to a JSON format (for example, using Bio), and then read it with various JSON parsers (like the rjson package in R, which parses a JSON file to a list of records). Refer to the tutorial for more details. For this example I will be using the E.coli K12 genome, which clocks in at around 13 mbytes. Parse the specified handle into a GenBank record. Typically in this case you just want to get integer positions back for where to slice: This is still rather tricky, and it gets worse for complex situations like joins. Is there a more recent similar source? The script produces no errors, but only writes information from the first 1/2 of the genbank file before terminating.
