例如,我正在使用远程 (NCBI) 服务器为数千个 EST 序列运行独立的 Blast+。我没有收到任何状态消息,例如 100 个序列中的 15 个正在运行。是否有可能获得任何这样的状态消息?或任何其他方式使用perl脚本一个接一个地发送序列?
非常感谢!

我建议使用 Bioperl ( http://metacpan.org/pod/BioPerl ) 和Bio::Tools::Run::RemoteBlast
模块。请参阅http://metacpan.org/pod/Bio::Tools::Run::RemoteBlast,这是他们在 RemoteBlast.pm 模块中提供的代码示例
while (my $input = $str->next_seq()){
#Blast a sequence against a database:
#Alternatively, you could pass in a file with many
#sequences rather than loop through sequence one at a time
#Remove the loop starting 'while (my $input = $str->next_seq())'
#and swap the two lines below for an example of that.
my $r = $factory->submit_blast($input);
#my $r = $factory->submit_blast('amino.fa');
print STDERR "waiting..." if( $v > 0 );
while ( my @rids = $factory->each_rid ) {
foreach my $rid ( @rids ) {
my $rc = $factory->retrieve_blast($rid);
if( !ref($rc) ) {
if( $rc < 0 ) {
$factory->remove_rid($rid);
}
print STDERR "." if ( $v > 0 );
sleep 5;
} else {
my $result = $rc->next_result();
#save the output
my $filename = $result->query_name()."\.out";
$factory->save_output($filename);
$factory->remove_rid($rid);
print "\nQuery Name: ", $result->query_name(), "\n";
while ( my $hit = $result->next_hit ) {
next unless ( $v > 0);
print "\thit name is ", $hit->name, "\n";
while( my $hsp = $hit->next_hsp ) {
print "\t\tscore is ", $hsp->score, "\n";
}
}
}
}
}
}
查看方法retrieve_blast
(http://metacpan.org/pod/Bio::Tools::Run::RemoteBlast#retrieve_blast)。它将返回一个状态代码,让您知道爆破作业是否完成。如果您有更多问题,请告诉我,我会尝试进一步澄清。
