Anto_ch has asked for the wisdom of the Perl Monks concerning the following question:
Hi all
I am quite new to perl, I am writing a script to extract multiple columns from a tab delimited text files that is the output of a previous script.
The out put files look like this:
column1 column2 column3 .... column n 111111 222222 333333 ..... nnnnnnn 121212 212121 313131 ...... nnnnnnn 131313 232323 343434 ...... nnnnnnn I would like to extract the second and the third column and put it on a new file, but with the code I wrote it enters the file but read and catch only the first number in column2. I don't know why it wan't iterate through the lines. Need help i am going crazy! :-) So far I had the same problem with another file where I have to subtract the values in column1 from columns 2 and it worked but when i tryied to use the same code to extract instead of subtracting catch only the first element of such column. thank you in advance for your help. code i am using is below:
