ああ文字列を切り取る

GFFはタブ区切り形式ですが、タブは使用しません。-F'\t'orを使用しない限り、BEGIN{FS="\t"}awkはスペースを含むすべてのスペースをフィールド区切り文字として使用します。スペースを切っているので、$9最初のスペースで終わります。 2つのコマンドも必要ありません。実行する必要がある作業は次のとおりです。

$ awk -F'\t' '$3=="mRNA"{print $9}' file.gff

値のみを取得するには、Note=次のようにします。

$ awk -F"\t" '$3=="mRNA"{sub(/.*Note=/,"",$9); print $9}' file.gff 
"Peptidase S59%2C nucleoporin"
"Putative S-adenosyl-L-methionine-dependent methyltransferase"
"Unknown"
"Heavy metal-associated domain%2C HMA"
"Unknown"
"Auxin response factor%2C B3 DNA binding domain%2C DNA-binding pseudobarrel domain%2C AUX/IAA protein%2C Aux/IAA-ARF-dimerisation"

そして、コメント自体に属することができる部分を維持しながら、コメントの先頭と末尾の引用符を削除するには、次の手順を実行します。

$ awk -F"\t" '$3=="mRNA"{sub(/.*Note=/,"",$9); print $9}' file.gff | sed 's/^"//; s/"$//'
Peptidase S59%2C nucleoporin
Putative S-adenosyl-L-methionine-dependent methyltransferase

Note最後に sum 値を取得するには、ID次のようにします。

$ awk -F"\t" '$3=="mRNA"{n=$9; sub(/.*Note="/,"",n); sub(/"$/,"",n); sub(/.*ID=/,"",$9); sub(/;.*/,"",$9); print $9","n}' file.gff

しかし、個人的に私はPerlでこれを行います。

$ perl -F'\t' -lane 'if($F[2] eq "mRNA"){/ID=([^\;]+).*Note="([^"]+)/; print "$1,$2"}' file.gff

各行の末尾にある引用文字列にタブやaを含めることができないと仮定すると、おそらく次;のようなものが必要になります。

または（元のアイデア）：

$ cat tst.awk
BEGIN { FS="\t"; OFS="," }
$3 == "mRNA" {
    split($NF,f,/;/)
    for (i in f) {
        gsub(/^[^=]+="?|"$/,"",f[i])
    }
    print f[1], f[7]
}

。

含めることができる場合は、OFSの,使用を再考し、タブまたは代わりを使用する必要があります。,;

ID=「最終結果」出力形式がフィールドから派生すると仮定すると、Note=次のことが機能します。

$ awk -F'\t' '$3=="mRNA"{split($9,f,";"); split(f[1],i,"="); split(f[7],n,"\""); printf("%s,%s\n",i[2],n[2])}' file.gff

これは、タブで区切られた9番目のフィールドを配列;に格納されている区切られたサブフィールドに分割しますf。ここで、最初のサブフィールド（ID=...）はで分割され、=7番目のサブフィールド（Note=" ... "）はで分割されて意味が分離されます。関心のある部分はそれぞれ補助配列"と区切ります。 。その後、これらの関連部分を印刷します。in

これはかなり簡潔なコードを可能にしますが、必ずしも最も効率的なアプローチではありません。

GNU awkを使う：

awk -F'\t' -vOFS=, 'NF>=9&&$3=="mRNA"{
N = split($9, a, /[=;]/)
for ( i=1; i<=N; i+=2 )
    h[a[i]] = a[i+1]
print h["ID"], gensub(/"(.*)"/, "\\1", "g", h["Note"])
}' bioinformatic.file
