extractfeat |
If the feature is annotated as being in the reverse sense of a nucleic acid sequence, then that feature's sub-sequence is reverse-complemented before being written out.
It is often useful to have some information on the context of the feature. extractfeat allows you to specify a number of bases or residues before and/or after the feature to write out.
If you are interested in extracting the sequence of the region around the start or end of the feature, then this can also be specified.
'joined' features can either be extracted as individual sequences, or as a single concatenated sequence if the '-join' qualifier is used.
Please remember that the output feature sequence is only as good as the annotation. If you rely upon other people's, or other program's annotation of features, then some of these will be incorrect.
To write out the exons of a sequence:

Mandatory qualifiers:
[-sequence] seqall Sequence database USA
[-outseq] seqout Output sequence USA
Optional qualifiers:
-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 se t this to match
any feature source you wish to show.
The source name is usuall y 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 u sing '*'.
If you wish to show more than one source,
separate their names with the character '|',
eg:
gene* | embl
-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://www3.ebi.ac.uk/Services/WebFeat/
for a list of the EMBL feature types and see
Appendix A of the Swissprot user manual in
http://www.expasy.ch/txt/userman.txt for a
list of the Swissprot 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
-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 If this is greater than or equal to the
maximum score, then any score is permitted
-maxscore float If this is less than or equal to the maximum
score, then any score is permitted
-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
-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 valueyou 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
-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.
-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.
-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

The sequences of the specified features are written out.
The ID name of the sequence is formed from the original sequence name with the start and end positions of the feature appended to it. So if the feature came from a sequence with an ID name of 'XYZ' from positions 10 to 22, then the resulting ID name of the feature sequence will be 'XYZ_10_22'
The name of the type of feature is added to the start of the description of the sequence in brackets, e.g.: '[exon]'.
The sequence is written out as a normal sequence.
If the feature is in the reverse sense of a nucleic acid sequence, then it is reverse-complemented before being written.
If you are extracting 'joined' features and one of more of the component features is in a different sequence entry, then the whole joined feature is ignored.
