# Bio::SeqIO::MultiFile(3pm)

Treating a set of files as a single input stream

## NAME

Bio::SeqIO::MultiFile - Treating a set of files as a single input stream

## SYNOPSIS

```
   my $seqin = Bio::SeqIO::MultiFile->new( -format => 'Fasta',
                                           -files  => ['file1','file2'] );
   while (my $seq = $seqin->next_seq) {
       # do something with $seq
   }
```

## DESCRIPTION

Bio::SeqIO::MultiFile provides a simple way of bundling a whole set of identically formatted sequence input files as a single stream. File format is automatically determined by `"Bio::SeqIO"`.
