For example, look at the CDS entry for hypothetical protein NEQ010: This is the twenty-seventh entry in the features list (one based counting), and so its element 26 in the list (zero based counting). I installed pcregrep (grep utility that uses Perl-style regexps) in Ubuntu with sudo apt install pcregrep. The Biopython package contains the SeqIO module for parsing and writing these formats which we use below. This index is then used to find the appropriate feature for updating.
