SYNOPSIS
anfo [ option | file ... ]DESCRIPTION
anfo aligns (short) sequencing reads to a (gigabase sized) database. It uses a heuristic seeding method, but then applies a genuine aligner that allows gaps, understands damage patterns in ancient dna and produces an easy to interpret score.Input files can be any variety of FastA or FastQ files, or a native anfo binary file, optinally compressed using gziporbzip2. The file format is automatically recognized and other formats may be added.
OPTIONS
- -V, --version
-
Print version number and exit.
- -o file, --output file
-
Write output to
file. file
will be written in the native
anfo
binary format, which can be operated upon using
anfo-tool
or the bindings to
guile.
- -c conffile, --config conffile
-
Read configuration from
conffile.
This file configures which indices are used, and by extension to which
genomes an alignment is made, what parameters to use in the aligner and
can set paths. See the example file.
- -p num, --threads num
-
Start
num
threads for alignment. One such thread per processor core is usually
best.
- -x num, --ixthreads num
-
Start
num
threads for indexing. Indexing normally uses less cpu power than
alignment, so fewer indexers than aligners is normally best.
- --solexa-scale
-
When reading FastQ files, use the Solexa scale (log-odds-ratios) instead
of the standard Phread scale (probabilities). If you use
Solexa/Illumina sequencers, refer to your documentation whether you need
this. Else you don't.
- --fastq-origin ori
-
Set origin for FastQ decoding to
ori.
The standard and default is 33, but it must be set to 64 for some
versions of the Solexa/Illumina software. If you use Solexa/Illumina
sequencers, refer to your documentation whether you need this. Else you
don't.
- -q, --quiet
-
Suppress all output except fatal errors.
- -v, --verbose
-
Print a progress indicator during operation.
ENVIRONMENT
- ANFO_PATH
-
Colon separated list of directories searched for genome and index files.
