READSEQ

NAME

readseq − Reads and writes nucleic/protein sequences in various formats

SYNOPSIS

readseq [-options] in.seq > out.seq

DESCRIPTION

This manual page documents briefly the readseq command. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page. Instead, it has documentation in text form, see below.

readseq reads and writes biosequences (nucleic/protein) in various formats. Data files may have multiple sequences. readseq is particularly useful as it automatically detects many sequence formats, and interconverts among them.

FORMATS

Formats which readseq currently understands:
* IG/Stanford, used by Intelligenetics and others
* GenBank/GB, genbank flatfile format
* NBRF format
* EMBL, EMBL flatfile format
* GCG, single sequence format of GCG software
* DNAStrider, for common Mac program
* Fitch format, limited use
* Pearson/Fasta, a common format used by Fasta programs and others
* Zuker format, limited use. Input only.
* Olsen, format printed by Olsen VMS sequence editor. Input only.
* Phylip3.2, sequential format for Phylip programs
* Phylip, interleaved format for Phylip programs (v3.3, v3.4)
* Plain/Raw, sequence data only (no name, document, numbering)
+ MSF multi sequence format used by GCG software
+ PAUP’s multiple sequence (NEXUS) format
+ PIR/CODATA format used by PIR
+ ASN.1 format used by NCBI
+ Pretty print with various options for nice looking output. Output
only.
+ LinAll format, limited use (LinAll and ConStruct programs)
+ Vienna format used by ViennaRNA programs
See the included "Formats" file for detail on file formats.

EXAMPLES

readseq

-- for interactive use

readseq my.1st.seq my.2nd.seq -all -format=genbank -output=my.gb

-- convert all of two input files to one genbank format output file

readseq my.seq -all -form=pretty -nameleft=3 -numleft -numright
-numtop -match

-- output to standard output a file in a pretty format

readseq my.seq -item=9,8,3,2 -degap -CASE -rev -f=msf -out=my.rev

-- select 4 items from input, degap, reverse, and uppercase them

cat *.seq | readseq -pipe -all -format=asn > bunch-of.asn

-- pipe a bunch of data thru readseq, converting all to asn
