HI,
thank you very much and sorry I did not read the rules (I did now), I posted my message a bit in a rush.
Anyway I tried your suggestions, but still there are some problems with it. For example:
open my $fh_in , '<', 'test1.txt' or die "Can not open file test1.txt:
+ $!";
open my $fh_out, '>', 'test2.txt' or die "Can not open file test2.txt:
+ $!";
while (<$fh_in>) {
s/\s+/\t/g;
print $fh_out "$_\n";
}
close $fh_out;
close $fh_in;
The code does the job but still there is a problem in the 5th column since there is not always an entry.
This is an example of my text file:
MGI:1918918 381629 0610007C
+21Rik 5 syntenic 51374
+ C2orf28 2p23.3 B
MGI:1918917 71667 0610007L
+01Rik 5 syntenic F 55069
+ C7orf42 7q11.21 C
MGI:1923501 76251 0610007P
+08Rik 13 syntenic B3 375748
+ C9orf102 9q22.32 M
MGI:1915571 58520 0610007P
+14Rik 12 syntenic 11161
+ C14orf1 14q24.3 B
In the lines with no entry in the 5 th column there should be second TAB. I currently work with an if(...){then....}
I hope it is clearer now, Thanks Martin

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
