[Bioperl-l] Permission denied when using Bio::SearchIO in CGI script

[Marcus Claesson]

Hello,

I want to use Bioperl's blast parser as an cgi script but have run into
some problems. There is no problem for my cgi script to open and read
files in my home directory using the classic:

open(OUT,">/home/marcus/file");

But when opening a blast output in the same place using:

use Bio::SearchIO;
$in = new Bio::SearchIO(-format => 'blast', 
 -file => '/home/marcus/file');
I get following permission denied message:
------------- EXCEPTION -------------
MSG: Could not open
/home/marcus/file for reading:
Permission denied
STACK Bio::Root::IO::_initialize_io
/usr/lib/perl5/site_perl/5.8.0/Bio/Root/IO.pm:244

STACK Bio::SearchIO::new
/usr/lib/perl5/site_perl/5.8.0/Bio/SearchIO.pm:134
STACK toplevel /var/www/cgi-bin/bxbrowser1.pl:15

Since people on the web will be opening their own files this can be
problem. Thus, how can I tell Bio::Search to 'not care' about the
permissions, or just change them? 

Really grateful for any help!
