Toolic,
I was trying to use the split function to parse a file with records. I realized
that was incorrect. I then looked at the record separator and attempted
to implement it and then use the split function.
I still had the same output. I used data dumper and I am able to see that only
the first line is being parsed. Here is my code and example file:


#!/usr/bin/perl -w
use strict;
use Data::Dumper;
# create scalar variable to define the file that will be 
# parsed.
my $genpept = "/Users/mgavibrathwaite/Desktop/proteins.gp";
#Set the global record separator to "//"
open(my $in,"$genpept");
undef $/; 
my @genpepts = split(/^\w{5}/,$in);
print Dumper(@genpepts);

            Summary: The protein encoded by this gene is a member of t
+he STAT
            protein family. In response to cytokines and growth factor
+s, STAT
            family members are phosphorylated by the receptor associat
+ed
            kinases, and then form homo- or heterodimers that transloc
+ate to
            the cell nucleus where they act as transcription activator
+s. This
            protein is activated through phosphorylation in response t
+o various
            cytokines and growth factors including IFNs, EGF, IL5, IL6
+, HGF,
            LIF and BMP2. This protein mediates the expression of a va
+riety of
            genes in response to cell stimuli, and thus plays a key ro
+le in
            many cellular processes such as cell growth and apoptosis.
+ The
            small GTPase Rac1 has been shown to bind and regulate the 
+activity
            of this protein. PIAS3 protein is a specific inhibitor of 
+this
            protein. Three alternatively spliced transcript variants e
+ncoding
            distinct isoforms have been described. [provided by RefSeq
+].
            
            Transcript Variant: This variant (1) represents the longes
+t
            transcript, and encodes the longest isoform (1).

COMMENT     REVIEWED REFSEQ: This record has been curated by NCBI staf

            Summary: The protein encoded by this gene is a member of t
+he STAT
            protein family. In response to cytokines and growth factor
+s, STAT
            family members are phosphorylated by the receptor associat
+ed
            kinases, and then form homo- or heterodimers that transloc
+ate to
            the cell nucleus where they act as transcription activator
+s. This
            protein is activated through phosphorylation in response t
+o various
            cytokines and growth factors including IFNs, EGF, IL5, IL6
+, HGF,
            LIF and BMP2. This protein mediates the expression of a va
+riety of
            genes in response to cell stimuli, and thus plays a key ro
+le in
            many cellular processes such as cell growth and apoptosis.
+ The
            small GTPase Rac1 has been shown to bind and regulate the 
+activity
            of this protein. PIAS3 protein is a specific inhibitor of 
+this
            protein. Three alternatively spliced transcript variants e
+ncoding
            distinct isoforms have been described. [provided by RefSeq
+].
            
            Transcript Variant: This variant (2) lacks a segment in th
+e 5' UTR
            and 3 nt within the CDS, as compared to variant 1. The res
+ulting
            isoform (2) lacks an amino acid compared to isoform 1.

The desired contents of my array would be the individual records which are
separated by LOCAL and //. Thanks for informing me to improve my posting.

You'll need to show us some example lines/records from your $genpept file to clarify what you are trying to achieve. Your code looks wrong on a number of levels. For example, you're opening the file but not actually reading from it (or even checking that the open succeeded). Also, the quoting around $genpept in open(my $in,"$genpept") is pointless.

If you want to slurp the whole file into the $in variable, you need something like:

open(my $fhin, '<', $genpept) or die "open '$genpept': $!";
undef $/;
my $in = <$fhin>;
[download]

Alternatively, if the file consists of multiple lines, it seems better to not slurp the whole file, but to read it line by line:

while (my $in = <$fhin>) {
   # ... split etc. done once for each line $in.
}
[download]

I suspect you are confused because your final print statement emits something like $VAR1 = 'GLOB(0x817f880)'. As for why:

• You never set the global separator to "//". You merely defined it to nothing at all. To set the record separator to "//", you do local $/='//'. That will break your input stream into records ending with '//'.
• You never read in your file. Your split statement is attempting to split the string representation of an input handle, i.e. 'GLOB(...)', not the contents of your inputfile. To read a file into an array you need to use <$in>. To remove the '//' from the end you need to use chomp.

Your code should look something like this if you want to read in everything in one gulp:

local $/='//';        #define record separator
my @records = <$in>;  # read in all records
chomp @records;       #get rid of trailing // from each record
[download]

Or this, which reads in one record at a time and is much more memory efficient

local $/='//';
while (my $record = <$in>) {
  chomp $record;   #remove // from end of line
  #... process the record ...
}
[download]

my @genpepts = split(/^\w{5}/,$in);
[download]

You seem to be describing a file like:

LOCAL
asrdf asfd afd asdf aafd
qwer qwer qre qwre qrew
//
LOCAL
asrdf asfd afd asdf aafd
qwer qwer qre qwre qrew
//
[download]

use split() when you know what to throw away.
use match global when you know what you want to keep.

lomSpace: Many thanks for posting an exact copy of your huge example data three separate times. The monastery had some server space it was desperate to kill. Thanks also for making sure that the string 'LOCAL' for which you say you are interested in processing the data never once appears anywhere in said data.
