textsearch |
Please help by correcting and extending the Wiki pages.
textsearch searches for words (specified as a regular expression) in the description text of one or more input sequences. It writes an output file with optional contents such as the name, description and accession number of any sequence whose description line from the annotation matches the search term. Optionally, the search is case-sensitive and the results output as an HTML table. textsearch is convenient for small input files but will be slow for larger files and databases; you should use use SRS or Entrez instead.
textsearch searches only the description line, not the full sequence annotation.
Search for 'lactose':
% textsearch "tsw:*" "lactose" Search the textual description of sequence(s) Output file [12s1_arath.textsearch]: ajSeqxrefNewDbS '1-I' 'FT025' |
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 the textual description of sequence(s) Output file [bgal_ecoli.textsearch]: |
Go to the input files for this example
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 the textual description of sequence(s) |
Go to the output files for this example
Search the textual description of sequence(s)
Version: EMBOSS:6.4.0.0
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)
[-outfile] outfile [*.textsearch] Output file name
Additional (Optional) qualifiers:
-casesensitive boolean [N] Do a case-sensitive search
-html boolean [N] Format output as an HTML table
Advanced (Unprompted) qualifiers:
-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 -nousa -noacc -nodesc'
to get only the name output, you can specify
'-only -name'
-heading boolean [@(!$(only))] Display column headings
-usa boolean [@(!$(only))] Display the USA of the
sequence
-accession boolean [@(!$(only))] Display 'accession' column
-name boolean [@(!$(only))] Display 'name' column
-description boolean [@(!$(only))] Display 'description' column
Associated qualifiers:
"-sequence" associated qualifiers
-sbegin1 integer Start of each sequence to be used
-send1 integer End of each sequence to be used
-sreverse1 boolean Reverse (if DNA)
-sask1 boolean Ask for begin/end/reverse
-snucleotide1 boolean Sequence is nucleotide
-sprotein1 boolean Sequence is protein
-slower1 boolean Make lower case
-supper1 boolean Make upper case
-sformat1 string Input sequence format
-sdbname1 string Database name
-sid1 string Entryname
-ufo1 string UFO features
-fformat1 string Features format
-fopenfile1 string Features file name
"-outfile" associated qualifiers
-odirectory3 string Output directory
General qualifiers:
-auto boolean Turn off prompts
-stdout boolean Write first file to standard output
-filter boolean Read first file from standard input, write
first file to standard output
-options boolean Prompt for standard and additional values
-debug boolean Write debug output to program.dbg
-verbose boolean Report some/full command line options
-help boolean Report command line options and exit. More
information on associated and general
qualifiers can be found with -help -verbose
-warning boolean Report warnings
-error boolean Report errors
-fatal boolean Report fatal errors
-die boolean Report dying program messages
-version boolean Report version number and exit

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.

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.
