我正在努力尝试组合来自两个文件的部分匹配的字符串.
文件1包含唯一字符串列表.这些字符串与文件2中的许多字符串部分匹配.如何为每个匹配的大小写合并文件1中的行和文件2
文件1
mmu-miR-677-5p_MIMAT0017239 mmu-miR-181a-1-3p_MIMAT0000660
文件2
mmu-miR-677-5p_CTTCAGTGATGATTAGCTTCTGA mmu-miR-677-5p_CTTCAGTGATGATTAGCTTCTGACT mmu-miR-677-5p_TTCAGTGATGATTAGCTTCTGACT mmu-miR-181a-1-3p_ACCATCGACCGTTGATTGTAC mmu-miR-181a-1-3p_ACCATCGACCGTTGATTGTACC
期望的输出
mmu-miR-677-5p_MIMAT0017239 mmu-miR-677-5p_CTTCAGTGATGATTAGCTTCTGA mmu-miR-677-5p_MIMAT0017239 mmu-miR-677-5p_CTTCAGTGATGATTAGCTTCTGACT mmu-miR-677-5p_MIMAT0017239 mmu-miR-677-5p_TTCAGTGATGATTAGCTTCTGACT mmu-miR-181a-1-3p_MIMAT0000660 mmu-miR-181a-1-3p_ACCATCGACCGTTGATTGTAC mmu-miR-181a-1-3p_MIMAT0000660 mmu-miR-181a-1-3p_ACCATCGACCGTTGATTGTACC
我尝试在R中使用pmatch(),但是没有把它弄好.我看起来像perl会处理的东西？
也许是这样的：
perl -ne'exec q;perl;,"-ne",q $print (/\Q$.$1.q;/?"$. YES":$. .q\; NO\;);,"file2" if m;^(.*)_pat1;' file1
解决方法
这是一个简短的Perl解决方案,它将来自file1的所有数据保存在哈希中,然后在扫描file2时检索它
use strict;
use warnings;
use autodie;
my @files = qw/ file1.txt file2.txt /;
my %file1 = do {
open my $fh,'<',$files[0];
map /([^_]+)_(\S+)/,<$fh>;
};
open my $fh,$files[1];
while (<$fh>) {
my ($key) = /([^_]+)/;
printf "%-32s%s","${key}_$file1{$key}",$_;
}
