NAME

asn2all - generate reports from ASN.1 biological data

SYNOPSIS

asn2all [-] [-A acc] [-T] [-X] [-a type] [-b] [-c] [-d path] [-f format] [-h] [-i filename] [-k] [-l] [-n policy] [-o filename] [-p path] [-r] [-v filename] [-x ext]

DESCRIPTION

asn2all is primarily intended for generating reports from the binary ASN.1 Bioseq-set release files downloaded from the NCBI ftp site (ncbi-asn1 directory). It can produce GenBank and GenPept flatfiles, FASTA sequence files, INSDSet structured XML, TinySeq XML, and Sequin-style 5-column feature tables.

The release files (which have the extension .aso.gz) should be uncompressed with gunzip(1), resulting in files with the extension .aso. For example, gbpri1.aso is the first file in the primate division, and the command

gunzip gbpri1.aso.gz

will result in gbpri1.aso being created. The original gbpri1.aso.gz file is removed after successful decompression.

In asn2all, the name of the file to be processed is specified by the -i command line argument. Use -a t to indicate that it is a release file and -b to indicate that it is binary ASN.1. A text ASN.1 file obtained from Entrez can be processed by using -a a instead of -a t -b.

Nucleotide and protein records can be processed simultaneously. Use the -o argument to indicate the nucleotide output file, and the -v argument for the protein output file.

The -f argument determines the format to be generated, and is documented in more detail (along with other options) in the following section.

OPTIONS

A summary of options is included below.

-

Print usage message

-A acc

Accession to fetch

EXtended qualifier output

-a type

Input ASN.1 type:

a: Automatic (default)
z: Any
e: Seq-entry
b: Bioseq
s: Bioseq-set
m: Seq-submit
t: batch processing (suitable for official releases; autodetects specific type)

-b

Bioseq-set is Binary

-c

Bioseq-set is Compressed

-d path

Path to indexed binary ASN.1 Data

-f format

Output Format:

g: GenBank/GenPept (default)
f: FASTA
d: CDS FASTA
t: Sequin-style 5-column feature table
y: TinySet XML (akin to FASTA)
s: INSDSet XML (akin to GenBank/GenPept)
a: structurally equivalent text ASN.1
x: structurally equivalent XML
c: cache components

-h

Display extra Help message

-i filename

Input file name (standard input by default)

-k

Enable local fetching

-l

Lock components in advance

-n policy

Near FASTA policy:

a: All
n: Near only (default)
f: Far only

-o filename

Nucleotide Output file name

-p path

Path to files

-r

Enable Remote fetching

-v filename

Protein output file name

-x ext

File selection suffix when working with entire directories. (default is .aso)

EXAMPLES

The command

asn2all -i gbpri1.aso -a t -b -f g -o gbpri1.nuc -v gbpri1.prt

will generate GenBank and GenPept reports from gbpri1.aso.
