次のバイオインフォマティクスの質問のためにPerlスクリプトを作成しましたが、残念ながら出力に問題があります。
質問
1)40,000の一意のシーケンスのファイルから、一意はシーケンスID番号を意味し、次のパターンを抽出します
$gpat = [G]{3,5}; $npat = [A-Z]{1,25};<br>
$pattern = $gpat.$npat.$gpat.$npat.$gpat.$npat.$gpat;
2)シーケンスごとに、次$pattern
の値の間に発生する かどうかを確認します。
- 0〜100
- 100〜200
- 200〜300
- ..。
- 900-1000
1000
特定のシーケンスの長さが1000文字未満の場合でも、除算を維持する必要があります。つまり、0〜100、100〜200などです。
問題
私が抱えている主な問題は、シーケンスの細分化ごとに$ patternが発生する回数をカウントし、次にすべてのシーケンスのカウントを加算することです。
たとえば、シーケンス1の場合、$patternが1000を超える長さで5回発生するとします。シーケンス2の場合、$patternが長さ>1000で3回発生するとします。その場合、合計数は5 + 3=8になります。
代わりに、私の結果は次のようになります:(5 + 4 + 3 + 2 + 1)+(3 + 2 + 1)= 21つまり、累積合計。
それぞれ100文字の最初の10個のサブディビジョンのカウントで同じ問題に直面しています。
この計算に正しいコードを提供できれば幸いです。
私が書いたコードは以下の通りです。これは、ここでの私の以前の質問の1つに対するボロディンの答えから大きく派生しています:Perl:配列要素全体でパターンを検索する
彼の答えはここにあります:https ://stackoverflow.com/a/11206399/1468737
コード:
use strict;
use warnings;
my $gpat = '[G]{3,5}';
my $npat = '[A-Z]{1,25}';
my $pattern = $gpat.$npat.$gpat.$npat.$gpat.$npat.$gpat;
my $regex = qr/$pattern/i;
open my $fh, '<', 'small.fa' or die $!;
my ($id, $seq);
my @totals = (0, 0, 0, 0, 0, 0, 0, 0, 0, 0); #intialize the @total arrays...
#..it should contain 10 parts for 10 divisions upto 1000bp
my @thousandcounts =(0); #counting total occurrences of $pattern at >1000 length
while (<$fh>) {
chomp;
if (/^>(\w+)/) {
process_seq($seq) if $id;
$id = $1;
$seq = '';
print "$id\n";
}
elsif ($id) {
$seq .= $_;
process_seq($seq) if eof;
}
}
print "Totals : @totals\n";
print "Thousand Counts total : @thousandcounts\n";
##**SUBROUTINE**
sub process_seq {
my $sequence = shift @_;
my $subseq = substr $sequence,0,1000;
my $length = length $subseq;
print $length,"\n";
if ($length eq 1000) {
my @offsets = map {sprintf '%.0f', $length * $_/ 10} 1..10;
print "Offsets of 10 divisions: @offsets\n";
my @counts = (0, 0, 0, 0, 0, 0, 0, 0, 0, 0);
my @count = (0);
while ($sequence =~ /$regex/g) {
my $place = $-[0];
print $place,"\n\n";
if ($place <=1000){
for my $i (0..9) {
next if $place >= $offsets[$i];
$counts[$i]++;
last;
}
}
print "Counts : @counts\n\n";
$totals[$_] += $counts[$_] for 0..9;
if ($place >1000){
for my $i(0){
$count[$i]++;
last;
}
} print "Count greater than 1000 : @count\n\n";
$thousandcounts[$_] += $count[$_] for 0;
}
}
#This region of code is for those sequences whose total length is less than 1000
#It is working great ! No issues here
elsif ($length != 1000) {
my $substr = join ' ', unpack '(A100)*', $sequence;
my @offsets = map {sprintf '%.0f', $length * $_/ ($length/100)} 1..10;
print "Offsets of 10 divisions: @offsets\n";
my @counts = (0, 0, 0, 0, 0, 0, 0, 0, 0, 0,);
while ($sequence =~ /$regex/g) {
my $place = $-[0];
print "Place : $place","\n\n";
for my $i (0..9) {
next if $place >= $offsets[$i];
$counts[$i]++; .
last;
}
}
print "Counts : @counts\n\n";
$totals[$_] += $counts[$_] for 0..9;
}
}#subroutine ends
また、作業しているファイルの小さなセグメントを添付しています。これはタイトルが付けられsmall.fa
ており、40,000を超えるシーケンスを含むより大きなファイルに移動する前にのみ、このファイルを実験してきました。
