# gene2xml(1)

convert NCBI Entrez Gene ASN.1 into XML

## NAME

gene2xml - convert NCBI Entrez Gene ASN.1 into XML

## SYNOPSIS

**gene2xml** \[**-**\] \[**-b**\] \[**-c**\] \[**-i** *filename*\] \[**-l**\] \[**-o** *filename*\] \[**-p** *path*\] \[**-r** *path*\] \[**-t** *N*\] \[**-x**\] \[**-y**\] \[**-z**\]

## DESCRIPTION

**gene2xml** is a stand-alone program that converts Entrez Gene ASN.1 into XML. Entrez Gene data are stored as compressed binary Entrezgene-Set ASN.1 files on the NCBI ftp site, and have the suffix **.ags.gz**. These are several-fold smaller than compressed XML files, resulting in a significant savings of disk storage and network bandwidth. Normal processing by gene2xml produces text XML files with the same name but with **.xgs** as the suffix.

## OPTIONS
