in reply to PROTEIN FILE help me pleaseee
Hi serafinososi,
...If the line starts with “>” (it is the first line of a FASTA file) the line is not considered...
What if the line that starts with ">" is more than one in the file what happens?
If I understand the OP's question, using the data provided, if I may suggest (adding to what others have said) using perl function split may do like so:
use warnings; use strict; my $protein; while (<DATA>) { if (/^>/) { next; } else { $protein = join '', split; } } my $number_of_F = grep { /F/ } split //, $protein; print "The aminoacid sequence: ", $protein, " contains ", $number_of_F +, " Phenylalanine aminoacids", $/; __DATA__ >gi|403369491|gb|EJY84591.1| Transcriptional regulator, Sir2 family pr +otein Oxytricha trifallax MMKQLIKHNKNTPLFNFLRVKFSSTAATIQTQQTVNKPIESKFKEEKLDNYHDIYEKSKRLAEQISQSKS + FICFTGAGLSTSTGIPDYRSTSNTLAQTGAGAYELEISEEDKKSKTRQIRSQVQRAKPSISHMALHAL +ME NGYLKHLISQNTDGLHLKSGIPYQNLTELHGNTTVEYCKSCSKIYFRDFRCRSSEDPYHHLTGRQC +EDLK CGGELADEIVHFGESIPKDKLVEALTAASQSDLCLTMGTSLRVKPANQIPIQTIKNKGQLAIVN +LQYTPF DEIAQIRMHSFTDQVLEIVCQELNIKIPEYQMKRRIHIIRNAETNEIVVYGSYGNHKNIKLS +FMQRMEYI DNKNHVYLALDKEPFHIIPDYFNFQNINTDQEEVEFRIHFYGHNSEPYFQLTLPRQSILE +LQAGEHLICD ITFDYDKLEWK
If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
