Your task is to parse out an EMBL record (see file attached) just like we did for GenBank records in the discussions. 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. This is compatible with -n/--nucleotide, -o/--orfs, and By default, the file handler opens a file in the read mode. In general Bio.SeqIO.parse () is used to read in sequence files as SeqRecord objects, and is typically used with a for loop like this: In [2]: # we show the first 3 only for i, seq_record in enumerate (SeqIO.parse ("data/ls_orchid.fasta", "fasta")): print (seq_record.id) print (repr (seq_record.seq)) print (len (seq_record)) if i == 2: break After parsing, there will be one ParsedAnnotationRecord built for every sequence in the GenBank file. Research What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? I also installed Biopython with sudo apt install python3-biopython and ran the Simple GenBank parsing example from Biopython Tutorial and Cookbook. When you switch back to using featureCount, you're now looking at records where the "type" is not "CDS". We'll then loop over the list of features to find the desired CDS features: In [1]: # Biopython's SeqIO module handles sequence input/output from Bio import SeqIO def get_cds_feature_with_qualifier_value(seq_record . It provides lot of parsers to read all major genetic databases like GenBank, SwissPort, FASTA, etc., as well as wrappers/interfaces to run other popular bioinformatics software/tools like NCBI BLASTN, Entrez, etc., inside the python environment. Making statements based on opinion; back them up with references or personal experience.
