## Function

Display basic information about sequences

## Description

infoseq displays on screen basic information about one or more input sequences. This includes the Uniform Sequence Address (USA), name, accession number, type (nucleic or protein), length, percentage C+G and description. Any combination of these records is easily selected or unselected for display. The same information may be written to an output file which (optionally) may be formatted in an HTML table.

## Usage

Here is a sample session with infoseq

Display information on a sequence:

    % infoseq tembl:x13776
    Display basic 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
    Display basic information about sequences

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

Example 3

Display only the name and length of a sequence:

    % infoseq tembl:x13776 -only -name -length
    Display basic information about sequences

    Name           Length
    X13776         2167

Example 4

Display only the description of a sequence:

    % infoseq tembl:x13776 -only -desc
    Display basic information about sequences

    Description
    Pseudomonas aeruginosa amiC and amiR gene for aliphatic amidase regulation

Example 5

Display the type of a sequence:

    % infoseq tembl:x13776 -only -type
    Display basic information about sequences

    Type
    N

Example 6

Display information formatted with HTML:

    % infoseq tembl:x13776 -html
    Display basic information about sequences

    tembl-id:X13776temblX13776X13776N216766.54Pseudomonas aeruginosa amiC and amiR gene for aliphatic amidase regulation

## Command line arguments

    Display basic information about sequences
    Version: EMBOSS:6.2.0

       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)
       -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
       -seqversion         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:

- The USA (Uniform Sequence Address) that EMBOSS can use to read in the sequence.
- The name or ID of the sequence. If this is not known then '-' is output.
- The accession number. If this is not known then '-' is output.
- The type ('N' is nucleic, 'P' is protein).
- The sequence length.
- The description line of the sequence. This may be blank.

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

There are many qualifiers to control exactly what information on the sequence is output and how it is formatted. If you only want a few fields in the output file, the command line may be shortended by preceding the appropriate qualifier with `-only`. For example, instead of specifying `-nohead -noname -noacc -notype -nopgc -nodesc` to get only the length output, you can specify `-only -length`.

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.
