基本上,我需要一个可以在很短的时间内解决问题的脚本。我有两个文件:
$头-n 6 fcu.tsv
NM576455 0.324009324 0.578896174 2577
NM539570 0.204545455 0.607877092 2247
NM337132 0.288973384 0.673636364 792
NM374379 0.308300395 0.42 762
NM373443 0.263043478 0.547132867 1383
NM371839 0.298210736 0.492857143 1512
$ 头 -n 6 集市.tsv
NM539570 ILMN_2199362 15 58.52 protein_coding
NM576455 ILMN_2195138 1 65.74 protein_coding nucleus cellular_component SAM_2
NM576455 ILMN_2195138 1 65.74 protein_coding protein binding molecular_function SAM_2
NM576455 ILMN_1709067 1 65.74 protein_coding nucleus cellular_component SAM_2
NM576455 ILMN_1709067 1 65.74 protein_coding protein binding molecular_function SAM_2
NM576455 ILMN_2195138 1 65.74 protein_coding nucleus cellular_component SAM_type1
我们需要在很短的时间内为每个 NM id 将 fcu.tsv 的第 2、3 和 4 个字段附加到 mart.tsv。
$ head out.tsv
NM539570 ILMN_2199362 15 58.52 protein_coding 0.204545455 0.607877092 2247

NM576455 ILMN_1709067 1 65.74 protein_coding protein binding molecular_function SAM_2 0.324009324 0.578896174 2577

这就是我在 matlab 中所做的(我更喜欢该解决方案在此处修复错误代码以使其更快,而不是编写新代码)
fr1 = fopen('fcu.tsv', 'r');
fr2 = fopen('mart.tsv', 'r');
fw = fopen('out.tsv', 'w');
while feof(fr1) == 0
line = fgetl(fr1);
scan = textscan(line, '%s%f%f%d');
frewind(fr2);
while feof(fr2) == 0
line2 = fgetl(fr2);
scan2 = textscan(line2, '%s%s%s%f%s%s%s%s');
if scan{1}{1} == scan2{1}{1}
fprintf(fw, '%s\t%f\t%f\t%d\n', line2, scan{2}, scan{3}, scan{4});
end
end
end
