DESCRIPTION

       extractfeat is a command line program from EMBOSS (“the European Molecular Biology Open Software Suite”).
       It is part of the "Edit,Feature tables" command group(s).

OPTIONS

   Input section
       -sequence seqall

   Additional section
       -before integer
           If this value is greater than 0 then that number of bases or residues before the feature are included
           in the extracted sequence. This allows you to get the context of the feature. If this value is
           negative then the start of the extracted sequence will be this number of bases/residues before the
           end of the feature. So a value of '10' will start the extraction 10 bases/residues before the start
           of the sequence, and a value of '-10' will start the extraction 10 bases/residues before the end of
           the feature. The output sequence will be padded with 'N' or 'X' characters if the sequence starts
           after the required start of the extraction.

       -after integer
           If this value is greater than 0 then that number of bases or residues after the feature are included
           in the extracted sequence. This allows you to get the context of the feature. If this value is
           negative then the end of the extracted sequence will be this number of bases/residues after the start
           of the feature. So a value of '10' will end the extraction 10 bases/residues after the end of the
           sequence, and a value of '-10' will end the extraction 10 bases/residues after the start of the
           feature. The output sequence will be padded with 'N' or 'X' characters if the sequence ends before
           the required end of the extraction.

       -source string
           By default any feature source in the feature table is shown. You can set this to 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, separate their names with the
           character '|', eg: gene* | embl Default value: *

       -type string
           By default every feature in the feature table is extracted. You can set this to be any feature type
           you wish to extract. See http://www.ebi.ac.uk/embl/WebFeat/ for a list of the EMBL feature types and
           see the Uniprot user manual in http://www.uniprot.org/manual/sequence_annotation for a list of the
           Uniprot feature types. The type may be wildcarded by using '*'. If you wish to extract more than one
           type, separate their names with the character '|', eg: *UTR | intron Default value: *

       -sense integer
           By default any feature type in the feature table is extracted. You can set this to match any feature
           sense you wish. 0 - any sense, 1 - forward sense, -1 - reverse sense

       -minscore float
           Minimum score of feature to extract (see also maxscore) Default value: 0.0

       -maxscore float
           Maximum score of feature to extract. If both minscore and maxscore are zero (the default), then any
           score is ignored Default value: 0.0

       -tag string
           Tags are the types of extra values that a feature may have. For example in the EMBL feature table, a
           'CDS' type of feature may have the tags '/codon', '/codon_start', '/db_xref', '/EC_number',
           '/evidence', '/exception', '/function', '/gene', '/label', '/map', '/note', '/number', '/partial',
           '/product', '/protein_id', '/pseudo', '/standard_name', '/translation', '/transl_except',
           '/transl_table', or '/usedin'. Some of these tags also have values, for example '/gene' can have the
           value of the gene name. By default any feature tag in the feature table is extracted. You can set
           this to match any feature tag you wish to show. The tag may be wildcarded by using '*'. If you wish
           to extract more than one tag, separate their names with the character '|', eg: gene | label Default
           value: *

       -value string
           Tag values are the values associated with a feature tag. Tags are the types of extra values that a
           feature may have. For example in the EMBL feature table, a 'CDS' type of feature may have the tags
           '/codon', '/codon_start', '/db_xref', '/EC_number', '/evidence', '/exception', '/function', '/gene',
           '/label', '/map', '/note', '/number', '/partial', '/product', '/protein_id', '/pseudo',
           '/standard_name', '/translation', '/transl_except', '/transl_table', or '/usedin'. Only some of these
           tags can have values, for example '/gene' can have the value of the gene name. 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 a space or the character '|', eg: pax* | 10 Default value: *

   Output section
       -join boolean
           Some features, such as CDS (coding sequence) and mRNA are composed of introns concatenated together.
           There may be other forms of 'joined' sequence, depending on the feature table. If this option is set
           TRUE, then any group of these features will be output as a single sequence. If the 'before' and
           'after' qualifiers have been set, then only the sequence before the first feature and after the last
           feature are added. Default value: N

       -featinname boolean
           To aid you in identifying the type of feature that has been output, the type of feature is added to
           the start of the description of the output sequence. Sometimes the description of a sequence is lost
           in subsequent processing of the sequences file, so it is useful for the type to be a part of the
           sequence ID name. If you set this to be TRUE then the name is added to the ID name of the output
           sequence. Default value: N

       -describe string
           To aid you in identifying some further properties of a feature that has been output, this lets you
           specify one or more tag names that should be added to the output sequence Description text, together
           with their values (if any). For example, if this is set to be 'gene', then if any output feature has
           the tag (for example) '/gene=BRCA1' associated with it, then the text '(gene=BRCA1)' will be added to
           the Description line. Tags are the types of extra values that a feature may have. For example in the
           EMBL feature table, a 'CDS' type of feature may have the tags '/codon', '/codon_start', '/db_xref',
           '/EC_number', '/evidence', '/exception', '/function', '/gene', '/label', '/map', '/note', '/number',
           '/partial', '/product', '/protein_id', '/pseudo', '/standard_name', '/translation', '/transl_except',
           '/transl_table', or '/usedin'. Some of these tags also have values, for example '/gene' can have the
           value of the gene name. By default no feature tag is displayed. You can set this to match any feature
           tag you wish to show. The tag may be wildcarded by using '*'. If you wish to extract more than one
           tag, separate their names with the character '|', eg: gene | label

       -outseq seqout
