 * formats. Data files may have multiple sequences.

Readseq has been updated.   There have been a number of enhancements
and a few bug corrections since the previous general release in Nov 91
(see below).  If you are using earlier versions, I recommend you update to
this release.

Readseq is particularly useful as it automatically detects many
sequence formats, and interconverts among them.
Formats added to this release include
  + 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.

As well, Phylip format can now be used as input.  Options to
reverse-compliment and to degap sequences have been added.  A menu
addition for users of the GDE sequence editor is included.

This program is available thru Internet gopher, as

  gopher ftp.bio.indiana.edu
  browse into the IUBio-Software+Data/molbio/readseq/ folder
  select the readseq.shar document

Or thru anonymous FTP in this manner:
  my_computer> ftp  ftp.bio.indiana.edu  (or IP address 129.79.224.25)
    username:  anonymous
    password:  my_username@my_computer
  ftp> cd molbio/readseq
  ftp> get readseq.shar
  ftp> bye

readseq.shar is a Unix shell archive of the readseq files.
This file can be editted by any text editor to reconstitute the
original files, for those who do not have a Unix system or an
Unshar program.  Read the top of this .shar file for further
instructions.

There are also pre-compiled executables for the following computers:
Silicon Graphics Iris, Sparc (Sun Sparcstation & clones), VMS-Vax,
Macintosh. Use binary ftp to transfer these, except Macintosh.  The
Mac version is just the command-line program in a window, not very
handy.

C source files:
  readseq.c ureadseq.c ureadasn.c ureadseq.h
Document files:
  Readme (this doc)
  Readseq.help (longer than this doc)
  Formats (description of sequence file formats)
  add.gdemenu (GDE program users can add this to the .GDEmenu file)
  Stdfiles -- test sequence files
  Makefile -- Unix make file
  Make.com -- VMS make file
  *.std    -- files for testing validity of readseq


Example usage:
  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


The brief usage of readseq is as follows. The "[]" denote
optional parts of the syntax:

Recent changes:

4 May 92
+ added 32 bit CRC checksum as alternative to GCG 6.5bit checksum
Aug 92
= fixed Olsen format input to handle files w/ more sequences,
  not to mess up when more than one seq has same identifier,
  and to convert number masks to symbols.
= IG format fix to understand ^L
30 Dec 92
* revised command-line & interactive interface.  Suggested form is now
    readseq infile -format=genbank -output=outfile -item=1,3,4 ...
  but remains compatible with prior commandlines:
    readseq infile -f2 -ooutfile -i3 ...
+ added GCG MSF multi sequence file format
+ added PIR/CODATA format
+ added NCBI ASN.1 sequence file format
+ added Pretty, multi sequence pretty output (only)
+ added PAUP multi seq format
+ added degap option
+ added Gary Williams (GWW, G.Williams@CRC.AC.UK) reverse-complement option.
+ added support for reading Phylip formats (interleave & sequential)
* string fixes, dropped need for compiler flags NOSTR, FIXTOUPPER, NEEDSTRCASECMP
* changed 32bit checksum to default, -DSMALLCHECKSUM for GCG version

1Feb93
= reverted Genbank output format to fixed left margin 
  (change in 30 Dec release), so GDE and others relying on fixed margin
  can read this.
