bash를 이용해서 이런 작업을 하려고 합니다.

cat 1.txt | grep -A 2.txt | sed -n -e '1,/>/ {/>/ !' > myout.txt

답변1

시퀀스가 실제로 한 줄에만 있는 경우 간단히 다음을 사용할 수 있습니다.

$ grep -f 1.txt 2.txt

fasta 파일을 사용하고 있습니다. 따라서 저는 이 목적을 위해 특별히 설계된 기존 프로그램을 사용하는 것을 강력히 권장합니다.시퀀스 키트

$ seqkit grep -r -f 1.txt 2.txt

seqkit의 표준 출력은 60자 이후의 시퀀스를 새 줄로 나눕니다. 여전히 한 줄에 있도록 하려면 결과를 seqkit seq다음과 같이 전달하십시오.

$ seqkit grep -r -f 1.txt 2.txt|seqkit seq -w0

답변2

awk -F '|' 'FNR == NR { id[$1]; next } /^>/ && ($2 in id) { print; getline; print }' 1.txt 2.txt

이 awk프로그램은 다음 설명과 함께 독립형 awk스크립트로 제공됩니다.

BEGIN {
    # Set input field separator to a pipe character.
    FS = "|"
}

FNR == NR {
    # This line comes from the first file.
    # Add the protein ID to the id array as a key,
    # then immediately continue with the next cycle.

    id[$1]
    next
}

# The rest will only ever be executed while reading the second file.

/^>/ && ($2 in id) {
    # This line is a Fasta header line (starts with >),
    # and the ID found in the second field is an index in the id array.

    print;   # output the current line (Fasta header)
    getline; # get the next line
    print;   # output that line too (Fasta sequence)
}

이는 모든 단백질 서열이 항상 한 줄만 사용한다고 가정합니다(즉, Fasta 파일에는 여러 줄 서열이 존재하지 않습니다).

스크립트는 먼저 단백질 ID가 포함된 파일을 읽고 이를 기억합니다. 그런 다음 Fasta 파일에서 읽고 첫 번째 파일에서 읽은 단백질 ID와 관련된 헤더 및 시퀀스를 출력합니다.

답변3

이 시도,

# grep -A1 -F -f  1.txt 2.txt | grep -v '\-\-'

  • -FPATTERN을 고정된 문자열 목록으로 해석

  • -f한 줄에 하나씩 FILE에서 패턴을 가져옵니다.

답변4

Perl5 사용

이것은 여러 줄의 시퀀스를 처리합니다.

process.pl

STDIN의 키와 args의 데이터 파일을 가져옵니다.

use v5.10;
my %keys;
while (<STDIN>) {
  chomp;
  $keys{$_} = undef;
}
while ( <<>> ) {                  # read from args
  state $s = 0;                   # State; $s==1 for print
  if (/^>/) {                     # In header
    my $id = [split '\|',3]->[1]; #   get id
    $s = exists $keys{$id};       #   check for id in keys, set $s
  }
  print if $s;                    # check $s and print
}
