You are expected to use this module via the Bio.SeqIO functions. The "tab" format is an ad-hoc plain text file format where each sequence is on one (long) line. Each line contains the identifier/description, followed by a tab, followed by the sequence. For example, consider the following short FASTA format file:: >ID123456 possible binding site? CATCNAGATGACACTACGACTACGACTCAGACTAC >ID123457 random sequence ACACTACGACTACGACTCAGACTACAAN Apart from the descriptions, this can be represented in the simple two column tab separated format as follows:: ID123456(tab)CATCNAGATGACACTACGACTACGACTCAGACTAC ID123457(tab)ACACTACGACTACGACTCAGACTACAAN When reading this file, "ID123456" or "ID123457" will be taken as the record's .id and .name property. There is no other information to record. Similarly, when writing to this format, Biopython will ONLY record the record's .id and .seq (and not the description or any other information) as in the example above. )Seq) SeqRecord)_clean)_get_seq_string)SequenceIterator)SequenceWritercs0eZdZdZfddZddZddZZS) TabIteratorzParser for tab-delimited files.cstj|ddddS)aIterate over tab separated lines as SeqRecord objects. Each line of the file should contain one tab only, dividing the line into an identifier and the full sequence. Arguments: - source - file-like object opened in text mode, or a path to a file The first field is taken as the record's .id and .name (regardless of any spaces within the text) and the second field is the sequence. Any blank lines are ignored.
