Re^4: Aligning sequence

hi there I checked with both the stuffs you have mentioned. The last one the executable('blastall') didn't cause any errors. And as you have suggested shrinking the file size din't do any good, because it results in the same error but with different line numbers. I even tried with just a single seqeuence and even that results in

CAGCGATGGGGATCAAGCTC
Use of uninitialized value in pattern match (m//) at /usr/share/perl5/
+Bio/SeqIO/fasta.pm line 193, <GEN0> line 2.
Use of uninitialized value in print at /usr/share/perl5/Bio/Root/IO.pm
+ line 407, <GEN0> line 2.

-------------------- WARNING ---------------------
MSG: cannot find path to blastall

I have also included a bit of my input sequence:

I disagree. Since the script doesn't work with a single sequence, my third suggestion is most likely. An error like "`MSG: cannot find path to blastall`" seems to be the main and possibly only problem. Suggested fix: set the environmental variable $BLASTDIR or your $PATH variable to point to the BLAST directory.	[reply] [d/l]
