# asn2ff(1)

convert ASN.1 biological data to a flat format (old version)

## NAME

asn2ff - convert ASN.1 biological data to a flat format (old version)

## SYNOPSIS

**asn2ff** \[**-**\] \[**-A** *X*\] \[**-B** *X*\] \[**-C**\] \[**-G**\] \[**-L F**\] \[**-M**\] \[**-R**\] \[**-V F**\] \[**-a** *filename*\] \[**-b**\] \[**-d**\] \[**-e**\] \[**-f** *b/p/e/s/x/z*\] \[**-g**\] \[**-h F**\] \[**-k F**\] \[**-l** *filename*\] \[**-m** *r/d/s/c/k/l/e/p*\] \[**-n F**\] \[**-o** *filename*\] \[**-p F**\] \[**-q**\] \[**-r** *filename*\] \[**-s**\] \[**-t**\] \[**-v F**\] \[**-w**\] \[**-y**\] \[**-z**\]

## DESCRIPTION

**asn2ff** converts descriptions of biological sequences from NCBI's ASN.1 format to one of several flat-file formats.  This program is built around a deprecated interface; please use **asn2gbFP(1) instead.**
