NAME

       abacas - Algorithm Based Automatic Contiguation of Assembled Sequences

SYNOPSIS

       abacas -r ref -q qs -p prog  [OPTIONS]

       OR

       abacas -r ref -q psf -e

       ref    reference sequence in a single fasta file

       qs     contigs in multi-fasta format

       rog    MUMmer program to use: 'nucmer' or 'promer'

       psf    pseudomolecule/ordered sequence file in fasta format

       OPTIONS

       -h     print usage

       -d     use default nucmer/promer parameters

       -s     int     minimum length of exact matching word (nucmer default = 12, promer default = 4)

       -m     print ordered contigs to file in multifasta format

       -b     print contigs in bin to file

       -N     print a pseudomolecule without "N"s

       -i     int     mimimum percent identity [default 40]

       -v     int     mimimum contig coverage [default 40]

       -V     int     minimum contig coverage difference [default 1]

       -l     int     minimum contig length [default 1]

       -t     run tblastx on contigs that are not mapped

       -g     string (file name)      print uncovered regions (gaps) on reference to file name

       -a     append contigs in bin to the pseudomolecule

       -o     prefix  output files will have this prefix

       -P     pick primer sets to close gaps

       -f     int     number of flanking bases on either side of a gap for primer design (default 350)

       -R     int     Run mummer [default 1, use -R 0 to avoid running mummer]

       -e     Escape contig ordering i.e. go to primer design

       -c     Reference sequence is circular

DESCRIPTION

       ABACAS is intended to rapidly contiguate (align, order, orientate), visualize and design primers to close gaps on shotgun assembled contigs
       based on a reference sequence.

       ABACAS  uses  MUMmer to find alignment positions and identify syntenies of assembled contigs against the reference. The output is then pro-
       cessed to generate a pseudomolecule taking overlapping contigs and gaps in to account. ABACAS generates a comparision file that can be used
       to  visualize ordered and oriented contigs in ACT. Synteny is represented by red bars where colour intensity decreases with lower values of
       percent identity between comparable blocks. Information on contigs such as the orientation, percent identity,  coverage	and  overlap  with
       other contigs can also be visualized by loading the outputted feature file on ACT.
