我有一个文件，其中记录的格式如下:
I've a file with records in this type of format:

LOCUS NG_032962 70171 bp DNA linear PRI 17-JUN-2016 DEFINITION Homo sapiens death domain containing 1 (DTHD1), RefSeqGene on
chromosome 4. ACCESSION NG_032962 VERSION NG_032962.1 KEYWORDS RefSeq; RefSeqGene. SOURCE Homo sapiens (human) ORGANISM Homo sapiens
Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi;
Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini;
Catarrhini; Hominidae; Homo. COMMENT REVIEWED REFSEQ: This record has been curated by NCBI staff. The
reference sequence was derived from AC104078.3.
This sequence is a reference standard in the RefSeqGene project.
Summary: This gene encodes a protein which contains a death domain.
Death domain-containing proteins function in signaling pathways and
formation of signaling complexes, as well as the apoptosis pathway.
Alternative splicing results in multiple transcript variants.

我一直在使用此工作流程:
Ive been using this workflow:
-
删除空格
gawk '{$1=$1}1' raw_file.text > temp_file.txt
remove spaces
gawk '{$1=$1}1' raw_file.text > temp_file.txt
匹配摘要"内容gawk /Summary/,/\]/{print} temp_file.text > summary_temp.txt
删除新行gawk 'BEGIN {RS=""}{gsub(/\n/,"",$0); print $0}' summary_temp.text > summary.txt
我有几个问题.首先，我如何结合这三个步骤.其次，如何选择一个或多个其他匹配项，例如匹配项'/gene ="AP3B2"'(需要匹配"gene"之后的"/gene"的第一个实例)，以便我可以在其中输出内容形式:
I've a couple of questions.First, how could I combine those 3 steps.Second, how could I also select one or more additional matches, for example match '/gene="AP3B2"' (which requires matching the first instance of "/gene" after "gene") so that I could output the contents in this form:
基因，摘要
推荐答案
$ cat tst.awk
BEGIN{RS="//"}
{
match($0, /\/gene="([^"]+)"/, a)
print a[1] ", ",
gensub(/\s\s+/, "", "g", gensub(/.*Summary:\s([^\[]+).*/, "\\1", "g"))
}
说明:
match($0, /\/gene="([^"]+)"/, a)
捕获数组a中的所有"\ gene"部分.根据您的问题，只需要第一次出现，即a [1](而不是AP3B2，btw).
catches all "\gene" parts in array a. According to your question only the first occurrence is needed, which is a[1] (and is not AP3B2, btw).
gensub(/.*Summary:\s([^\[]+).*/, "\\1", "g")
捕获摘要:"之后的所有内容，直到找到"["为止.最后的结果包含空格和换行符.让我们摆脱它们:
catches everything after "Summary: " until you find a "[".This last result has spaces and newlines. Let's get rid of them:
gensub(/\s\s+/, "", "g", <<result of 1st gensub>>)
将脚本更改为:
$ cat tst.awk
BEGIN{RS="//"}
{
match($0, /\/gene="([^"]+)"/, a)
match($0, /Summary:\s([^\[]+)/, b)
print a[1] ",",
gensub(/\s\s+/, " ", "g", b[1])
}
使用OP提供的输入来运行脚本:
Running the script with input provided by OP:
awk -f tst.awk tst.txt
OR6K3,
REEP1, This gene encodes a protein which contains a death domain.Death
domain-containing proteins function in signaling pathways andformation
of signaling complexes, as well as the apoptosis pathway.Alternative
splicing results in multiple transcript variants.
