    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.

      Formats (description of sequence file formats)
      add.gdemenu (GDE program users can add this to the .GDEmenu 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.
