Function: train AUGUSTUS and run AUGUSTUS completly and automatically
Usage:
autoAug.pl [OPTIONS] --species=sname --genome=genome.fa --cdna=cdna.fa --trainingset=genesfile
autoAug.pl [OPTIONS] --species=sname --genome=genome.fa --cdna=cdna.fa --pasa
autoAug.pl [OPTIONS] --species=sname --genome=genome.fa --trainingset=genesfile [--estali=cdna.psl] [--hints=hints.gff]
--genome=fasta fasta file with DNA sequences for training
--trainingset=genesfile genesfile contains training genes in Genbank, GFF or protein FASTA format
--species=sname species name as used by AUGUSTUS
--hints=hints.gff hints for gene predictions with AUGUSTUS
--estali=cdna.psl cDNA alignments in PSL format (as generated by BLAT and GMAP) are used to construct UTRs
--pasa use PASA to construct a training set
--cdna=cdna.fa a fasta file with cDNA sequences (ESTs, mRNA)
--pasapolyAhints use PASA polyA hints as hints for the prediction
options:
--useexisting use and change the present config and parameter files if they exist for 'species'
--verbose print more status info. Cumulative option, e.g. use -v -v -v to make this script very verbose
--noutr do not train and predict UTRs.
--workingdir=/path/to/wd/ In the working directory results and temporary files are stored.
Default: current working directory
--singleCPU run the complete program sequentially instead of parallel execution of jobs on a cluster
--noninteractive bypass all manual interaction when using a SGE cluster
--cname=yourClusterName cluster name, only use it wenn "noninteractive" default:fe
--index=i step index, default:0
--optrounds=n optimization rounds - each meta parameter is optimized this often (default 1)
--maxIntronLen=n maximal length of an intron as used by PASA and BLAT, not by AUGUSTUS (default 100000)
--useGMAPforPASA use GMAP instead of BLAT in the PASA run
--help print this usage information
