[BiO BB] BLAST problem - .index files

[Samantha Fox]

Hi !
I got this wierd observation.. not really a problem or error, as BLAST runs
fine and gives me the output .. but something to know about.

So I format the nucleotide database as normal 'formatdb -i data -p F -o T'
.. and this makes all the relevant files.

However, I noticed that after some BLAST runs, a .index file and .index.___
also appear !! and the next BLAST runs give this sort of exception:

------------- EXCEPTION  -------------
MSG: Can't open cache file data.index: Invalid argument
STACK Bio::DB::Fasta::_open_index
/usr/local/lib/perl5/site_perl/5.8.5/Bio/DB/Fasta.pm:502
STACK Bio::DB::Fasta::index_file
/usr/local/lib/perl5/site_perl/5.8.5/Bio/DB/Fasta.pm:607
STACK Bio::DB::Fasta::new
/usr/local/lib/perl5/site_perl/5.8.5/Bio/DB/Fasta.pm:467
STACK toplevel get_ortho.pl.all:43


Any BLAST experts here, who can help !

thanks ..
