Sorry for not writing a detailed description of what i am working on. So i have thousands of files in a tab delimited format saved in one folder.
Each file has a format of 2000 by 10 table
What i want to do right now is create new file with the data i want.
So the format of each file follows ..
Gene exp1 exp2 exp3 exp4 ...
1 1050 2020 100 100
2 100 100 100 100
3 224 11 11 11
4 11 15 555 444
5 22 51 55 555
6 55 55 55 555
...
From the first file i read, I want to extract two columns for example I want 'Gene' and 'exp4' columns and put it in a new file.
And from the rest of the other files, I want to extract 'exp4' column only and add on the right side of the two columns i extracted from the first file.
So the final format would look like
Gene file1 exp4 file2 exp4 file3 exp4 file4 exp4....
1 100 200 155 144
2 22 55 222 444
3
4
5
6
.
.
So it will have a 2000 by thousands(number of my files) table as a result.
I am a beginner in programming and especially in perl.
help me please..
