General hints

Our practicals are held in “Aula Informatica di Biologia” (formerly Taliercio) in Via Paolotti. See the Calendar.

  • Take your seat and log in with your own account.
  • Try to read carefully all the instructions. Skim the whole post before starting, take some time (1h, 1h 30m…) to work alone before asking for help. This is a good practice as Google will help you for the rest of your life ­čÖé
  • Save files as requested with the correct┬áfilename and within the correct┬ádirectory. Instructors will look for them.
  • Always try to understand the meaning of what we do.

  • Perl is CaSe sensitive
