Section below for dealing with ambiguousįile formats which may contain more than one alignment.Ī further optional alphabet argument allowing you to specify theĮxpected alphabet. There is also an optional seq_count argument which is discussed in As in Bio.SeqIO we don’t try and guess the file format The second argument is a lower case string specifying the alignmentįormat.The first argument is a handle to read the data from, typically an.In this case, you should use theīio.AlignIO.read() function which returns a singleīoth functions expect two mandatory arguments: However, in many situations you will be dealing with files which contain Water or needle, or Bill Pearson’s FASTA tools. Seqboot, or multiple pairwise alignments from the EMBOSS tools Examples of situations where you will have multiple differentĪlignments include resampled alignments from the PHYLIP tool Using () will return an iterator which gives We have two functions for reading in sequence alignments,īio.AlignIO.read() and () which following theĬonvention introduced in Bio.SeqIO are for files containing one or Where to go from here – contributing to Biopython.Sequence motif analysis using Bio.motifs.BLAST and other sequence search tools ( experimental code).Getting your alignment objects as formatted strings.Converting between sequence alignment file formats.
