NAME
FAST::Bio::Search::Result::HmmpfamResult - A parser and result object for hmmpfam results
SYNOPSIS
# generally we use FAST::Bio::SearchIO to build these objects
my
$in
= FAST::Bio::SearchIO->new(
-format
=>
'hmmer_pull'
,
-file
=>
'result.hmmer'
);
while
(
my
$result
=
$in
->next_result) {
$result
->query_name,
" "
,
$result
->algorithm,

,
$result
->num_hits(),
" hits\n"
;
}
DESCRIPTION
This object implements a parser for hmmpfam result output, a program in the HMMER package.

Support
Please direct usage questions or support issues to the mailing list:

APPENDIX
The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
new
Title : new
Usage :
my
$obj
= FAST::Bio::SearchIO::Result::hmmpfam->new();
Function: Builds a new FAST::Bio::SearchIO::Result::hmmpfam object
Returns : FAST::Bio::SearchIO::Result::hmmpfam
Args :
-chunk
=> [FAST::Bio::Root::IO,
$start
,
$end
] (required
if
no
-parent)
-parent
=> FAST::Bio::PullParserI object (required
if
no
-chunk)
-parameters
=> hash
ref
of search parameters (
key
=> value), optional
-statistics
=> hash
ref
of search statistics (
key
=> value), optional
where the array
ref
provided to -chunk contains an IO object
for
a filehandle to something representing the raw data of the
result, and
$start
and
$end
define the
tell
() position within the
filehandle that the result data starts and ends (optional; defaults
to start and end of the entire thing described by the filehandle)
next_hit
Title : next_hit
Usage :
while
(
$hit
=
$result
->next_hit()) { ... }
Function: Returns the
next
available Hit object, representing potential
matches between the query and various entities from the database.
Returns : a FAST::Bio::Search::Hit::HitI object or
undef
if
there are
no
more.
Args : none
next_model
Title : next_model
Usage :
my
$domain
=
$result
->next_model
Function: Returns the
next
domain - this is an alias
for
next_hit()
Returns : L<FAST::Bio::Search::Hit::HitI> object
Args : none
hits
Title : hits
Usage :
my
@hits
=
$result
->hits
Function: Returns the HitI objects contained within this Result
Returns : Array of FAST::Bio::Search::Hit::HitI objects
Args : none
See Also: FAST::Bio::Search::Hit::HitI
models
Title : models
Usage :
my
@domains
=
$result
->models;
Function: Returns the list of HMM models seen - this is an alias
for
hits()
Returns : Array of L<FAST::Bio::Search::Hit::HitI> objects
Args : none
sort_hits
Title : sort_hits
Usage :
$result
->sort_hits(
'<score'
)
Function : Sorts the hits so that they come out in the desired order
when
hits() or next_hit() is called.
Returns : n/a
Args : A coderef
for
the
sort
function. See the documentation on the Perl
sort
() function
for
guidelines on writing
sort
functions.
You will be sorting array references, not HitI objects. The
references contain name as element 0, description as element 1,
score as element 2, significance as element 3 and number of hsps
as element 4.
By
default
the
sort
order is ascending significance value (ie.
most significant hits first).
Note : To access the special variables
$a
and
$b
used by the Perl
sort
()
function the user function must access
FAST::Bio::Search::Result::HmmpfamResult namespace.
For example,
use
:
$result
->sort_hits(
sub
{
$FAST::Bio::Search::Result::HmmpfamResult::a
->[2]
<=>
$FAST::Bio::Search::Result::HmmpfamResult::b
->[2]});
NOT
$result
->sort_hits(
$a
->[2] <=>
$b
->[2]);
rewind
Title : rewind
Usage :
$result
->rewind;
Function: Allow one to
reset
the Hit iterator to the beginning, so that
next_hit() will subsequently
return
the first hit and so on.
Returns : n/a
Args : none
