Dear Monks,
I have a file with lines like the following:
AsmA_2               PF13502      220 A0KIJ1
AsmA_2               PF13502      220 A0KIJ1
DUF490               PF04357      379 A1AJD0
Pfam-B_5656          PB005656     259 A1AJD0
STN                  PF07660       52 T2MWK7
Secretin_N_2         PF07655       98 T2MZK3
Pfam-B_2175          PB002175     114 T2MVV9
Secretin_N           PF03958       82 U2ZRR1
Pfam-B_1479          PB001479     704 U2ZRR1
Pfam-B_2175          PB002175     114 U2ZRR1

The last code (e.g.A0KIJ1) should be my key. I want to store all info in one structure (as you can see there can be more than 1 lines referring to the same code. Which one must it be? Has of arrays? If so, how do I check, when reading the file line-by-line, that the code is the same or has changed?

In reply to What data structure must I use for this problem? by Anonymous Monk

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
