Deliberately incomplete, after all this is (your) homework, but you have some of your problems solved here... only because Oxytricha is a cute green thing

#!/usr/bin/perl -w use strict; my @protein = (); my $phenylcounter = 0; open (my $PROTEFILE, '<', $ARGV[0]) or die $!; # If the file is not existing it gives an error message # yup, I avoid the <STDIN> idea, solved by you. while ($line = <$PROTEFILE>) { # We read the lines of the file next if $line =~ m/^>/; # If the line starts with ">" + is not considered. $line =~ s/\s//g; # all white spaces removed from the line # Using the translate command, the program counts the number of F in +the sequence, assigning it to a variable. # left for you... tr/F//... $phenylcounter++} } # the while loop terminates close $PROTEFILE; # and the program continues closing the file. print "The aminoacid sequence", $ARGV[0], " contains ", $phenylcounter +, " Phenylalanine aminoacids"; print "\n"; # followed by new line

Updated: ($phenilcounter != $phenylcounter), fixed now
