## Function

Display protein sequences with features in pretty format

## Description

showpep displays one or more protein sequences, with features, in a style suitable for publication. The output is sent to screen by default but can be written to file. You may pick a format from a list, alternatively, use the many options to control what is output and in what format. Optionally, the sequence feature table can be displayed. There are various other options for controlling how the sequence is displayed and numbered and the output can be formatted for HTML.

## Usage

Here is a sample session with showpep

    % showpep tsw:laci_ecoli -sbeg 1 -send 100
    Display protein sequences with features in pretty format
    Things to display
             0 : Enter your own list of things to display
             1 : Sequence only
             2 : Default sequence with features
             3 : Pretty sequence 4:Baroque
    Display format [2]:

Example 2

The standard list of output formats are only a small selection of the possible ways in which a sequence might be displayed. Precise control over the output format is acheived by selecting the qualifier '-format 0' (Option 0 in the list of things to display). For example, by choosing format '0' and then specifying that we want to display the things: 'b,t,s', we will output the sequence in the following way:

    % showpep tsw:laci_ecoli -sbeg 1 -send 120
    Display protein sequences with features in pretty format
    Things to display
             0 : Enter your own list of things to display
             1 : Sequence only
             2 : Default sequence with features
             3 : Pretty sequence 4:Baroque
    Display format [2]: 0
    Specify your own things to display
             S : Sequence
             B : Blank line
             T : Ticks line
             N : Number ticks line
             F : Features
             A : Annotation
    Enter a list of things to display [B,N,T,S,A,F]: b,t,s
    Output file [laci_ecoli.showpep]:

Example 3

Display only the sequence:

    % showpep tsw:laci_ecoli -sbeg 1 -send 100 -noname -nodesc -format 0 -thing S
    Display protein sequences with features in pretty format
    Output file [laci_ecoli.showpep]:

Example 4

Protein sequence can be displayed in three-letter codes. (The codes are displayed downwards, so the first code is 'Met'):

    % showpep tsw:rs24_takru -three -format 2
    Display protein sequences with features in pretty format
    Output file [rs24_takru.showpep]:

Number the sequence lines in the margin:

    % showpep tsw:laci_ecoli -sbeg 1 -send 100 -format 1 -number
    Display protein sequences with features in pretty format
    Output file [laci_ecoli.showpep]:

Go to the output files for this example

Example 6

Start the numbering at a specified value ('123' in this case):

    % showpep tsw:laci_ecoli -sbeg 1 -send 100 -format 1 -number -offset 123
    Display protein sequences with features in pretty format
    Output file [laci_ecoli.showpep]:

Go to the output files for this example

Example 7

Make selected regions uppercase. (Use '-slower' to force the rest of the sequence to be lowercase).

    % showpep tsw:laci_ecoli -sbeg 1 -send 100 -format 1 -slower -upper "17-17,22-22"
    Display protein sequences with features in pretty format

Example 8

Add your own annotation to the display:

    % showpep tsw:laci_ecoli -sbeg 1 -send 100 -format 2 -send 120 -annotation "6-25 binding site 17-17 SNP 22-22 SNP"

                                      If this is left blank, then the sequence
                                      case is left alone.
                                      A set of regions is specified by a set of
                                      pairs of positions.
                                      The positions are integers.
                                      They are separated by any non-digit,
                                      non-alpha character.

                                      They are followed by any text (but not
                                      digits when on the command-line).
                                      Examples of region specifications are:

                                      match any feature source you wish to show.
                                      The source name is usually either the name
                                      of the program that detected the feature or
                                      it is the feature table (eg: EMBL) that the
                                      feature came from.
                                      The source may be wildcarded by using '*'.
                                      If you wish to show more than one source,

       -tagmatch           string     [*] Tags are the types of extra values that
                                      a feature may have. By default any feature
                                      tag in the feature table is shown. You can
                                      set this to match any feature tag you wish
                                      to show.
                                      The tag may be wildcarded by using '*'.
                                      If you wish to show more than one tag,

                                      table is shown. You can set this to match
                                      any feature tag value you wish to show.
                                      The tag value may be wildcarded by using

The tag may be wildcarded by using '*'. If you wish to show more than one tag, separate their names with the character '|', eg: gene | label | Any string | *
-valuematch | string | Tag values are the values associated with a feature tag. Tags are the types of extra values that a feature may have. By default any feature tag value in the feature table is shown. You can set this to match any feature tag value you wish to show. The tag value may be wildcarded by using '*'. If you wish to show more than one tag value, separate their names with the character '|', eg: pax* | 10 | Any string | *
-stricttags | boolean | By default if any tag/value pair in a feature matches the specified tag and value, then all the tags/value pairs of that feature will be displayed. If this is set to be true, then only those tag/value pairs in a feature that match the specified tag and value will be displayed. | Boolean value Yes/No | No

## Input file format

showpep reads one or more protein sequences.

The input is a standard EMBOSS sequence query (also known as a 'USA').

Major sequence database sources defined as standard in EMBOSS installations include srs:embl, srs:uniprot and ensembl

Data can also be read from sequence output in any supported format written by an EMBOSS or third-party application.

The input format can be specified by using the command-line qualifier `-sformat xxx`, where 'xxx' is replaced by the name of the required format. The available format names are: gff (gff3), gff2, embl (em), genbank (gb, refseq), ddbj, refseqp, pir (nbrf), swissprot (swiss, sw), dasgff and debug.

See: http://emboss.sf.net/docs/themes/SequenceFormats.html for further information on sequence formats.

You can specify a file of ranges to display in uppercase by giving the '-uppercase' qualifier the value '@' followed by the name of the file containing the ranges. (eg: '-upper @myfile').

The format of the range file is:

- Comment lines start with '#' in the first column.
- Comment lines and blank lines are ignored.
- The line may start with white-space.
- There are two positive (integer) numbers per line separated by one or more space or
- TAB characters.
- The second number must be greater or equal to the first number.
- There can be optional text after the two numbers to annotate the line.
- White-space before or after the text is removed.

An example range file is:

    # this is my set of ranges
    12   23
     4   5       this is like 12-23, but smaller
    67   10348   interesting region

You can specify a file of ranges to highlight in a different colour when outputting in HTML format (using the '-html' qualifier) by giving the '-highlight' qualifier the value '@' followed by the name of the file containing the ranges. (eg: '-highlight @myfile').

The format of this file is very similar to the format of the above uppercase range file, except that the text after the start and end positions is used as the HTML colour name. This colour name is used 'as is' when specifying the colour in HTML in a '' construct, (where 'xxx' is the name of the colour).

The standard names of HTML font colours are given in http://http://www.w3.org/TR/REC-html40/types.html#h-6.5

An example highlight range file is:

    # this is my set of ranges
    12   23         red
     4   5          darkturquoise
    67   10348      #FFE4E1

You can specify a file of ranges to annotate by giving the '-annotate' qualifier the value '@' followed by the name of the file containing the ranges. (eg: '-annotate @myfile').

The format of this file is very similar to the format of the above highlight range file, except that the text after the start and end positions is used as the displayed text of the annotated region.

An example annotation range file is:

    # this is my set of ranges
    12   23         exon 1
     4   5          CAP site
    67   10348      exon 2

Most of the variants of the output format have already been described in the 'Description' and 'Usage' sections, but here is some more just to fill out this section.

The output format is extremely variable and under the control of the qualifiers used.

The sequence can be formatted for HTML display by using the '-html' qualifier. The top and tail html tags <HEAD>, <BODY> etc. are not included as it is expected that the output of this program will be included in a more extensive HTML page and so these parts are left to the user to provide.

The name of the sequence is displayed, followed by the description of the sequence. These can be turned off with the '-noname' and '-nodescription' qualifiers.

Then the sequence is output, one line at a time. Any associated information to be displayed is also output above and below the sequence line, as specified by the '-format' and or '-things' qualifiers. (See the 'Description' section for detals).

The margins around the sequence are specified by the use of the '-margin' qaulifier and any numbering of the sequence and its translations are placed in the margin.

## Data files

EMBOSS data files are distributed with the application and stored in the standard EMBOSS data directory, which is defined by the EMBOSS environment variable EMBOSS_DATA.

To see the available EMBOSS data files, run:

    % embossdata -showall

To fetch one of the data files (for example 'Exxx.dat') into your current directory for you to inspect or modify, run:

    % embossdata -fetch -file Exxx.dat

Users can provide their own data files in their own directories. Project specific files can be put in the current directory, or for tidier directory listings in a subdirectory called ".embossdata". Files for all EMBOSS runs can be put in the user's home directory, or again in a subdirectory called ".embossdata".

The directories are searched in the following order:

- . (your current directory)
- .embossdata (under your current directory)
- ~/ (your home directory)
- ~/.embossdata

The Genetic Code data files are based on the NCBI genetic code tables. Their names and descriptions are:

EGC.0
  Standard (Differs from GC.1 in that it only has initiation site 'AUG')
EGC.1
  Standard
EGC.2
  Vertebrate Mitochodrial
EGC.3
  Yeast Mitochondrial
EGC.4
  Mold, Protozoan, Coelenterate Mitochondrial and Mycoplasma/Spiroplasma
EGC.5
  Invertebrate Mitochondrial
EGC.6
  Ciliate Macronuclear and Dasycladacean
EGC.9
  Echinoderm Mitochondrial
EGC.10
  Euplotid Nuclear
EGC.11
  Bacterial
EGC.12
  Alternative Yeast Nuclear
EGC.13
  Ascidian Mitochondrial
EGC.14
  Flatworm Mitochondrial
EGC.15
  Blepharisma Macronuclear
EGC.16
  Chlorophycean Mitochondrial
EGC.21
  Trematode Mitochondrial
EGC.22
  Scenedesmus obliquus
EGC.23
  Thraustochytrium Mitochondrial

The format of these files is very simple.

It consists of several lines of optional comments, each starting with a '#' character.

These are followed the line: 'Genetic Code [n]', where 'n' is the number of the genetic code file.

This is followed by the description of the code and then by four lines giving the IUPAC one-letter code of the translated amino acid, the start codons (indicdated by an 'M') and the three bases of the codon, lined up one on top of the other.

For example:

    ------------------------------------------------------------------------------
    # Genetic Code Table

    # and: http://www3.ncbi.nlm.nih.gov/htbin-post/Taxonomy/wprintgc?mode=c
    #
    # Differs from Genetic Code [1] only in that the initiation sites have been
    # changed to only 'AUG'

    Genetic Code [0]

    ------------------------------------------------------------------------------

The EMBOSS REBASE restriction enzyme data files are stored in directory 'data/REBASE/*' under the EMBOSS installation directory.

These files must first be set up using the program 'rebaseextract'. Running 'rebaseextract' may be the job of your system manager.

The data files are stored in the REBASE directory of the standard EMBOSS data directory. The names are:

- embossre.enz Cleavage information
- embossre.ref Reference/methylation information
- embossre.sup Supplier information

The column information is described at the top of the data files

The reported enzyme from any one group of isoschizomers (the prototype) is specified in the REBASE database and the information is held in the data file 'embossre.equ'. You may edit this file to set your own preferred prototype, if you wish.

The format of the file "embossre.equ" is
Enzyme-name Prototype-name

i.e. two columns of enzyme names separated by a space. The first name of the pair of enzymes is the name that is not preferred and the second is the preferred (prototype) name.

## Notes

One or more things may be selected for display from a menu (`-things` option). The order of specified characters (upper or lower case) determines the order in the output:

    s	Sequence
    b	Blank line
    t	Ticks line
    n	Number ticks line
    f	Features (from the feature table or from a command line -ufo file)
    a	User Annotation

Alternatively, there is a selection of pre-defined formats to choose from. The codes from above used in the list of standard formats are:

    Sequence only:                  S A
    Default sequence:               B N T S A F
    Pretty sequence:                B N T S A
    Baroque:                        B N T S T A F

The default standard format displays the following: for every new line that the sequence starts to write, the output display will contain first a blank line (`b`), then the position numbers of the ticks (`n`) then the ticks every 10 characters (`t`) then the sequence itself (`s`) then any user-supplied annotation (`a`) then the features from the feature table (`f`). Subsequent lines of the sequence output will repeat this format.

The output can be formatted for HTML. If the output is being formatted for HTML, then specified regions of the sequence can be displayed in any valid HTML colours.

If the sequence is in SwissProt format, the feature table of the sequence can be displayed with the sequence. GFF file features can also be displayed if they are included on the command line using `-ufo=file`.

Other display options include: The displayed sequence can be numbered either by numbering the start and ending positions, or by placing a ruler with ticks above or below the sequence. An initial position to start the numbering from can be set. The width of a line, and width of a margin around the sequence reserved for numbering can be set. Specified regions of the sequence can be displayed in uppercase to highlight them.
