## Function

## Description

seealso takes the name of an EMBOSS or EMBASSY program and returns a list of applications in the same functional group. Application names and short descriptions are listed. Optionally, the output is written to an HTML table.

## Usage

       Standard (Mandatory) qualifiers:
      [-search]            string     Enter the name of an EMBOSS program (Any
                                      string of at least 1 characters)

       Additional (Optional) qualifiers:
       -explode            boolean    [N] The groups that EMBOSS applications
                                      belong to have two forms, exploded and not
                                      exploded. The exploded group names are more
                                      numerous and often vaguely phrased than the
                                      non-exploded ones. The exploded names are
                                      formed from definitions of the group names
                                      that start like NAME1:NAME2 and which are
                                      then expanded into many combinations of the
                                      names as: 'NAME1', 'NAME2', 'NAME1 NAME2',
                                      NAME2 NAME1'. The non-expanded names are
                                      simply like: 'NAME1 NAME2'.
                                      Using expanded group names will find many
                                      more programs which share at least some of
                                      the expanded names than using the
                                      non-exploded names and so you will get more
                                      programs reported as sharing a similar
                                      function than you will if you specify that
                                      you wish to use non-exploded names
       -outfile            outfile    [stdout] Output file name

                                      this will format it for displaying as a
                                      table in a WWW document.
       -groups             boolean    [N] If you use this option, then only the
                                      group names will output to the file

       Advanced (Unprompted) qualifiers:

                                      program documentation will be searched. If

                                      the EMBASSY programs will be searched (if
                                      the -embassy option is true). EMBASSY
                                      programs are not strictly part of EMBOSS,

                                      developed by people who wish the programs to
                                      be outside of the GNU Public Licence scheme

                                      searched. EMBASSY programs are not strictly
                                      part of EMBOSS, but use the same code
                                      libraries and share the same look and feel,

                                      belong to have up to two levels, for example
                                      the primary group 'ALIGNMENT' has several
                                      sub-groups, or second-level groups, e.g.:
                                      CONSENSUS, DIFFERENCES, DOT PLOTS, GLOBAL,
                                      LOCAL, MULTIPLE. To aid programs that parse

Additional (Optional) qualifiers

The non-expanded names are simply like: 'NAME1 NAME2'.

## Input file format

## Output file format

The result is header line 'SEE ALSO' then a simple list of program names followed by the one-line description of the program.

If the '-html' qualifier is used, then the result is an HTML-formatted table, lacking the HTML document structures such as <HTML>, <BODY>, </BODY>, </HTML> which the user is expected to provide as the table will usually be included in the middle of a larger HTML document.

## Data files

None.

## Notes

The functional group of a program is set in its ACD file; this is an EMBOSS system file which specifies the application command-line interface such as required parameters, help on the parameters, one-line description of the program and so on. Normally the names of the groups are fairly specific. For example "NUCLEIC COMPOSITION" is a small group of applications for nucleotide sequence composition analysis.

The `-explode` qualifier will increase the number of groups that the program retrieves by splitting the group name at selected points to produce such groups as: "NUCLEIC", "NUCLEIC COMPOSITION" and "COMPOSITION". All programs with the exploded group names which also include "NUCLEIC" and "COMPOSITION" will now be reported. The result of this qualifier is thus a report of a larger number of programs with a more tenuous link to the specified program.

The groups that the program belongs to can be output by using the `-groups` qualifier.

## References

None.

## Warnings

The (optional) HTML-formatted table output lacks the HTML document structures such as
,
,
,
. It is expected the table will be included in the middle of a larger HTML document.

## Diagnostic Error Messages

The error message:

    FATAL ERROR: No application specified.

is output if a non-existent program name is specified.

## Exit status

The program exits with exist status '0' unless a non-existent program name is specified, when the exit status is '1'.

## Known bugs

None.
