Hi,all

i write a script to analyze the NCBI-blast output
i use bioperl 1.5.2_100
i encountened some wrong
it says:
Argument "1e" isn't numeric in numeric comparison (<=>) at
/usr/lib/perl5/site_perl/5.8.5/Bio/SearchIO/blast.pm line 661,
i searched the mailling list
and add "$E = "1" . $E if $E =~ /^e/;"
but the wrong message also happens to out
then i change a machine with bioperl 1.5.1 installed
all thing seems ok! no wrong message output!
so,how can i do some change to aviod the wrong message using the newest
bioperl?
Thanks!
