[Bioperl-l] [Bioperl-guts-l] Notification: incoming/921

[Hilmar Lapp]

If there are no args, this results in an empty string being
provided as the value for -file, which results in STDIN being
used, so it waits for input on STDIN.

In general I don't think it's the task of the bioperl core to
check whether your program was supplied with the required number
of arguments. Interpreting an empty string as a request for STDIN
is very convenient for many applications.

Module: Bio::SeqIO
Version: 0.7.0
PerlVer: 5.6.0

Submission from: iras-5-184.ucdavis.edu (169.237.12.184)


when execute without required parameters:

use Bio::SeqIO;

 $seqio = Bio::SeqIO->new (-file =>"$ARGV[0]" , -format =>
'Fasta') or die
"can't open sequence file";

system hang up.

But it works with required parameters.
In addition, it worked with bioperl 0.6.2
