Reads a sequence file into two columns: seq_name and sequence
This implementation uses the Biojava (VERSION 1.7.1) implementation for reading the data
It creates a sequence object that can be accessed by special nodes
The following file formats can be read in Fasta Genbank uniprot embl INSDseq
you also have to specify if the sequences are RNA, DNA, protein sequences
Annotations are stored with the sequence objects
Sample code to access annotation
Sample code to access sequence information
Large sequence files with lots of annotations might not fit into memory
