Hi, all.
I ran the bioperl script on suse10, the perl version was 5.8.7 and bioperl version was 1.6 . But there were some mistake, the following was the message the linux system feelback:
liaoy at linux:~/nd-hn> perl nd-hn.pl
Can't locate Bio/Tools/Run/Alignment/Clustalw.pm in @INC (@INC contains: /usr/lib/perl5/5.8.7/i586-linux-thread-multi/usr/lib/perl5/5.8.7/usr/lib/perl5/site_perl/5.8.7/i586-linux-thread-multi/usr/lib/perl5/site_perl/5.8.7/usr/lib/perl5/site_perl/usr/lib/perl5/vendor_perl/5.8.7/i586-linux-thread-multi/usr/lib/perl5/vendor_perl/5.8.7 /usr/lib/perl5/vendor_perl .) at nd-hn.pl line 26.
BEGIN failed--compilation aborted at nd-hn.pl line 26.
The detail of this script in two ways: the attached file and the following script.
Would you be kindly to test my script and give me some modification or suggestion?
I myself tested the script some time ago, and my judge was that: the first part(retrieve sequences from remote genebank) and the third part(get the conservative sequences of the multi- sequences alignment outputfile) were right, and the second part(using the Clustalw to do the multi- sequences alignment) encountered some problem? What the problem is? How can I correct it?
Thank you very much for your advice.
Best regards
