Hello, I'm very new to perl and I'm having a very difficult time organizing my script so that I can get it to do what I want it to do. Right now, I have a data file that is delimited by space, and has 12 columns, and 84000 rows. The only column that I care about is the 9th column. I am trying to organize the information in that column so that I can "count" the number of values given a conditional if statement (i.e. is the value in the list greater than 2.0, 3.0,...and so on.).
My issue is this. While creating a hash, I know I am supposed to assign a "key" to a "value". How do I specify a value that is >= 2 for example, assuming i'm not going to manually calculate the values greater than 2? And how do I get the hash to pull the information from the column, in my file.
