Class PrankCommandline

source code

                     object --+    
Application.AbstractCommandline --+

Command line wrapper for the multiple alignment program PRANK.


To align a FASTA file (unaligned.fasta) with the output in aligned FASTA format with the output filename starting with "aligned" (you can't pick the filename explicitly), no tree output and no XML output, use:

>>> from Bio.Align.Applications import PrankCommandline
>>> prank_cline = PrankCommandline(d="unaligned.fasta",
...                                o="aligned", # prefix only!
...                                f=8, # FASTA output
...                                notree=True, noxml=True)
>>> print(prank_cline)
prank -d=unaligned.fasta -o=aligned -f=8 -noxml -notree

You would typically run the command line with prank_cline() or via the Python subprocess module, as described in the Biopython tutorial.
