Function

   Search sequence documentation. Slow, use SRS and Entrez!

Description

   This is a small utility search for words in the description text of a
   sequence and for each match list the sequence's name and/or
   description. NB. It only searches the description line of the
   annotation, not the full annotation.

Usage

   Here is a sample session with textsearch

   Search for 'lactose':


% textsearch tsw:* 'lactose' 
Search sequence documentation. Slow, use SRS and Entrez!
Output file [100k_rat.textsearch]: 

   Go to the input files for this example
   Go to the output files for this example

   Example 2

   Search for 'lactose' or 'permease' in E.coli proteins:


% textsearch tsw:*_ecoli 'lactose | permease' 
Search sequence documentation. Slow, use SRS and Entrez!
Output file [laci_ecoli.textsearch]: 

   Go to the output files for this example

   Example 3

   Output a search for 'lacz' formatted with HTML to a file:


% textsearch tembl:* 'lacz' -html -outfile embl.lacz.html 
Search sequence documentation. Slow, use SRS and Entrez!

   Go to the input files for this example
   Go to the output files for this example

Command line arguments

   Standard (Mandatory) qualifiers:
  [-sequence]          seqall     (Gapped) sequence(s) filename and optional
                                  format, or reference (input USA)
  [-pattern]           string     The search pattern is a regular expression.
                                  Use a | to indicate OR.
                                  For example:
                                  human|mouse
                                  will find text with either 'human' OR
                                  'mouse' in the text (Any string is accepted)
  [-outfile]           outfile    [*.textsearch] Output file name

   Advanced (Unprompted) qualifiers:
   -only               boolean    [N] This is a way of shortening the command

                                  to get only the name output, you can specify

   -heading            boolean    [@(!$(only))] Display column headings

Input file format

   textsearch reads one or more normal sequence USAs.

  Input files for usage example

   'tsw:*' is a sequence entry in the example protein database 'tsw'

  Input files for usage example 3

   'tembl:*' is a sequence entry in the example nucleic acid database
   'tembl'

Output file format

  Output files for usage example

  File: 100k_rat.textsearch

# Search for: lactose
tsw-id:LACI_ECOLI LACI_ECOLI    P03023  LACTOSE OPERON REPRESSOR.
tsw-id:LACY_ECOLI LACY_ECOLI    P02920  LACTOSE PERMEASE (LACTOSE-PROTON SYMPOR
T).

  Output files for usage example 2

  File: laci_ecoli.textsearch

# Search for: lactose | permease
tsw-id:LACI_ECOLI LACI_ECOLI    P03023  LACTOSE OPERON REPRESSOR.
tsw-id:LACY_ECOLI LACY_ECOLI    P02920  LACTOSE PERMEASE (LACTOSE-PROTON SYMPOR
T).

  Output files for usage example 3

  File: embl.lacz.html

   Search for: lacz
   tembl-id:ECLAC ECLAC J01636 E.coli lactose operon with lacI, lacZ,
   lacY and lacA genes.
   tembl-id:ECLACZ ECLACZ V00296 E. coli gene lacZ coding for
   beta-galactosidase (EC 3.2.1.23).

   The first column in the name or ID of each sequence. The remaining
   text is the description line of the sequence.

   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>, <BODY>, </BODY> and </HTML> 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. So if '-nodesc' is used, there will not be any
   whitespace after the ID name.

Data files

   None.

Notes

   This is a rather slow way to search for text in databases. If you are
   searching for text in public databases, you should consider using
   either Entrez (http://www.ncbi.nlm.nih.gov/Entrez/) or SRS
   (http://srs.rfcgr.mrc.ac.uk/ or http://www.sanger.ac.uk/srs6/ etc.)

References

   None.

Warnings

   None.

Diagnostic Error Messages

   None.

Exit status

   It always exits with status 0

Known bugs

   None.
