Question

这是问题所在：我给AWK输入了一个以逗号分隔的表（并且表示FS =＆＃34;，＆＃34;），取第2-3列的平均值，第4-5列相同并打印第一列value \ t average1 \ t average2 \ n 但第一列有基因名，有些看起来像日期和当我打印时，这些名称会改变，例如＆＃34; Sept15＆＃34;改为＆＃34; 15-Sep＆＃34;，我想避免这个

awk 'BEGIN{FS=",";OFS="\t"}{if(NR==1){next}{print $1,($2+$3)/2,($4+$5)/2}}' DESeqResults.csv | grep Sep

即使使用printf（％s）

awk 'BEGIN{FS=",";OFS="\t"}{if(NR==1){next}{printf("%s\t%d\t%d\n",$1,($2+$3)/2,($4+$5)/2) }}' DESeqResults.csv | grep Sep

我认为使用printf而不仅仅是打印可以工作，但它没有。我非常确定在读取值并对其进行预处理时会发生一些事情，因为我只打印了该列和其他任何内容（使用print和printf）并且值已经更改。

awk 'BEGIN{FS=",";OFS="\t"}{if(NR==1){next}{print $1}}' DESeqResults.csv | grep Sep

以下是该表的示例：

genes,Tet2/3_Ctrtl_A,Tet2/3_Ctrtl_B,Tet2/3_DKO_A,Tet2/3_DKO_B,baseMean,baseMean_Tet2/3_Ctrtl,baseMean_Tet2/3_DKO,foldChange(Tet2/3_DKO/Tet2/3_Ctrtl),log2FoldChange,pval,padj

Answer 1

^{将大量评论转移到答案中}

没有; awk默认情况下不会将Sep15等字符串转换为日期15-Sep，即使在Mac上也是如此。至少，不是我测试过的Mac OS X 10.10.2 Yosemite上的标准awk，我也不希望它与awk的任何其他变体一起使用在Mac上看到。

[......时间过去了......] 令我惊讶的是，我安装了gawk，它是GNU Awk 3.1.7版权所有（C）1989,1991-2009自由软件基金会。（我知道我安装了gawk，但我希望它是4.x版本。）鉴于我的Mac上的数据，您的第一个awk（gawk）的输出您给出的数据命令在第一列上没有任何映射。如果您随后将数据导入电子表格，电子表格可以进行各种转换，但这不是awk的错误。

你在早期的一条评论中提到了Mac;你在使用Mac OS X吗？我不希望在电子表格之外发现任何问题。如果将数据导入电子表格，那么我会惊讶地发现类似日期的＆＃39;第1列中的值已重新格式化。

我尝试将问题中的数据导入LibreOffice（4.4.1.2或4.4.1002，具体取决于您查找版本号的位置），并且第1列中的数据未发生转换。同样，数字3.5.2和OpenOffice 4.1.1都将键从“9月”开始。单独

不幸的是，MS Excel（适用于Mac 2011，版本14.4.8 - 150116）会将此类列值转换为日期（例如，Sep15变为15-Sep。即使将列嵌入双引号也无济于事。除了＆＃34之外，我没有其他好的解决方案;不要使用MS Excel＆＃34;。

可能有一种方法可以抑制行为，但您需要问一个标记为excel和csv的问题，而不是awk和printing以及{{3} }。

顺便提一下，Google搜索＆＃39; excel csv import force text＆＃39;出现printf其中概述的一些技术（特别是＆＃34;将文件从.csv重命名为.txt＆＃34;技术）工作。

AWK避免重新格式化类似日期的值
