infoseq

 

Function

Displays some simple information about sequences

Description

This is a small utility to list the sequences' USA, name, accession number, type (nucleic or protein), length, percentage C+G, and/or description.

Any combination of these types of information can be easily selected or unselected.

By default, the output file starts each line with the USA of the sequence being described, so the output file is a list file that can be manually edited and read in by any other EMBOSS program that can read in one or more sequence to be analysed.

Usage

Here is a sample session with infoseq

Display information on a sequence:


% infoseq tembl:x13776 
Displays some simple information about sequences

USA                      Database  Name           Accession      Type Length %GC    Description 
tembl-id:X13776          tembl          X13776         X13776         N    2167   66.54  Pseudomonas aeruginosa amiC and amiR gene for aliphatic amidase regulation

Go to the input files for this example

Example 2

Don't display the USA of a sequence:


% infoseq tembl:x13776 -nousa

Command line arguments

   Standard (Mandatory) qualifiers:
  [-sequence]          seqall     (Gapped) sequence(s) filename and optional
                                  format, or reference (input USA)

   Additional (Optional) qualifiers:
   -outfile            outfile    [stdout] If you enter the name of a file
                                  here then this program will write the
                                  sequence details into that file.
   -html               boolean    [N] Format output as an HTML table

   Advanced (Unprompted) qualifiers:
   -[no]columns        boolean    [Y] Set this option on (Y) to print the
                                  sequence information into neat, aligned
                                  columns in the output file. Alternatively,
                                  leave it unset (N), in which case the
                                  information records will be delimited by a
                                  character, which you may specify by using
                                  the -delimiter option. In other words, if
                                  -columns is set on, the -delimiter option is
                                  overriden.
   -delimiter          string     [|] This string, which is usually a single
                                  character only, is used to delimit
                                  individual records in the text output file.
                                  It could be a space character, a tab
                                  character, a pipe character or any other
                                  character or string. (Any string is
                                  accepted)
   -only               boolean    [N] This is a way of shortening the command
                                  line if you only want a few things to be
                                  displayed. Instead of specifying:
                                  '-nohead -noname -noacc -notype -nopgc
                                  -nodesc'
                                  to get only the length output, you can
                                  specify
                                  '-only -length'
   -[no]heading        boolean    [Y] Display column headings
   -usa                boolean    [@(!$(only))] Display the USA of the
                                  sequence
   -database           boolean    [@(!$(only))] Display 'database' column
   -name               boolean    [@(!$(only))] Display 'name' column
   -accession          boolean    [@(!$(only))] Display 'accession' column
   -gi                 boolean    [N] Display 'GI' column
   -version            boolean    [N] Display 'version' column
   -type               boolean    [@(!$(only))] Display 'type' column
   -length             boolean    [@(!$(only))] Display 'length' column
   -pgc                boolean    [@(!$(only))] Display 'percent GC content'
                                  column
   -description        boolean    [@(!$(only))] Display 'description' column

Output file format

The output is displayed on the screen (stdout) by default.

The first non-blank line is the heading. This is followed by one line per sequence containing the following columns of data separated by one of more space or TAB characters:

If qualifiers to inhibit various columns of information are used, then the remaining columns of information are output in the same order as shown above, so if '-nolength' is used, the order of output is: usa, name, accession, type, description.

When the -html qualifier is specified, then the output will be wrapped in HTML tags, ready for inclusion in a Web page. Note that tags such as <HTML> and <BODY> are not output by this program as the table of databases is expected to form only part of the contents of a web page - the rest of the web page must be supplier by the user.

The lines of out information are guaranteed not to have trailing white-space at the end.

Data files

None.

Notes

This program was written to make it easier to get some specific bits of information on a sequence for use in small perl scripts. This Perl code fragment to get the type of a sequence is typical:
$type = `$PATH_TO_EMBOSS/infoseq $sequence -auto -only -type`;
chomp $type;

You may find other uses for it, of course.

By default, the output file starts each line with the USA of the sequence being described, so the output file is a list file that can be manually edited and read in by other EMBOSS programs using the list-file specification of '@filename'.

References

None.

Warnings

None.

Diagnostic Error Messages

None.

Exit status

It always exits with status 0

Known bugs

None noted.
