The lenght of the fragments can be controlled with the parameters -mind=#, and the distance to the anchor before dropping it (to avoid constraining the alignment by potentially mis-aligned anchor sites) is set with -dropd=#. If this softare installed is on your system, the option -a calls the anchoring program and breaks the search space into shorter fragments.

Try using this edited version of the program instead of the original.) (Note that some versions of the program have a bug in the routine reading the input flags and the anchoring fails. This option uses the anchoring algorithm chaos from the lagan package and requires the program to be on your execution path. The command-line version of the algorithm includes an experimental anchoring option that may radically reduce the computation time and allow for aligning sequences up to hundreds of kb's. The standard PRANK algorithm is based on an exhaustive search of the best pairwise solution, and for long sequences this soon becomes too time consuming. The PRANK algorithm uses insertion-deletion events as phylogenetic information and the results may be very sensitive to the given topology. If you know the correct phylogeny, import the tree with branch lengths and use it for alignment. To prevent PRANK running twice, use the flag '-once'.

You may also export a PRANK alignment, use a phylogeny software to infer a tree, import that (rooted) tree in PRANK, and realign the data. as filename.1.fas and filename.2.fas (the suffix automatically added in the end of the file name depends on the format chosen). The alignments produced at the stage (2) and (4) are named e.g. If you don't specify a guide tree, PRANK runs the alignment twice: (1) it generates a tree from unaligned data, (2) makes a multiple alignment, (3) generates a new guide based on the given alignment, and (4) makes an improved multiple alignment. Progressive alignment requires a guide tree, and PRANK can construct a tree using Neighbor Joining algorithm and evolutionary distances estimated from fast pairwise alignments. the model '+F' as defined in the paper) gives the most accurate results and should generally be used. Simulation studies with nucleotide sequences containing high numbers of insertions and deletions showed that the option '-F' (i.e. Translation into codons is done in the first forward frame without any error-checking. For protein coding DNA data, one can also use the empirical codon substitution model (kindly provided by Carolin Kosiol). WAG ( WG01) is used for protein alignments but, so far, the software isn't much tested for that and other programs may do better. With the optional command parameters, it supports TN ( TN93) and models below it (JC, K2P, FEL, HKY). Modelsįor DNA data, PRANK by default uses HKY model with empirical base frequencies and kappa=2. Type prank -help to see a brief description of optional parameters. The minimal command is prank filename where the file 'filename' contains more than one sequence in a format supported by the program readseq. If you wish to use the alignment software for your own studies, please send an email to Ari Loytynoja to be kept up to date with the bug fixes and improvements. The software is still under development and, in addition to lacking much error checking, may contain bugs.

Precompiled binaries are provided for MacOSX and Windows it should also compile fine on these platforms if the necessary tools are available. PRANK has been developed and best tested on Linux. The new version of PRANK available there includes bug fixes and significant speed improvements. The new prank-msa site contains the latest version of the program source code and allows entering comments and bug reports. NEW: PRANK development has moved to Google Code. PRANK is developed on Linux but works also on MacOSX and Windows. It is ideal for scripting and non-interactive work, and as it supports the MSAML-formatted output, the resulting alignments can always be browsed using the graphical front-end in PRANKSTER. PRANK is a command-line program that contains the latest features and the complete set of options.
